Crank length experiments

kooka-cranks

So after much research and inner reflection, meditation, intuitive hunches, signs from above etc. I decided that it’s only logical that a taller rider would best fit a longer length crank which would be relatively proportional to their leg length. Any other argument against it wasn’t logical to me.

Saying that a tall rider should ride a 175mm or even 180mm length crank that in reality isn’t long enough, is like saying that a 5′ 9″ tall rider with a 30″ inseam that normally rides a 172mm or 175mm cranks comfortably should instead ride a 150mm length crank, to get the most power out of their riding and a better more ideal fit.

For the record I’m 6′ 2″ with about a 34.5″ inseam, and my weight is usually anywhere from 190-230lbs. I’m not your typical sized rider, have been riding off an on for 20 years, road, MTB, touring etc.

So I purchased a custom length crank at 190mm, according to some calculations by long crank length proponents I could have even fit a 195mm, but I was concerned about chainstay, BB height, and toe/front tire clearance and thought better to lean on the short side with with my off the shelf commercial frame, in the future I might get a custom frame built to fit a 195-200mm crank, but we’ll see.

So here are my positive observations so far after riding the last two days on them. The only negative then I can think of is that my legs muscles and nerves have to get accustomed to turning a larger circle that I should have been turning all along. And that I’m so happy with my new cranks that I have buy another set for my MTB bike! hahaa

1. The cranks are heavy, but I don’t mind because relative to my size 200+lbs it doesn’t matter, the stiffness is more important I think, and these cranks are as stiff as they come.

2. I really like the 190mm I think this was a successful experiment

3. I put a set of FSA 50/34 chain rings on, ramped and pinned, they work great

8. I have no problem with rear chainstay or rear derailleur clearance.
9. No problems with front tire clearance
10. No problems with corning clearance that I’ve noticed yet.
11. I had to drop my seat about 15mm, which makes the whole bike feel different as my center of gravity is lower, but this actually feels good I think, I didn’t like that I was so high in the air pushing little cranks not using my legs all the way. So between my new lower center of gravity, and my wider foot stance in both directions I feel more stable and more part of the bike like a shorter rider does getting on a typical sized bike with typical length cranks I bet.
12. I can feel that my leg muscles and nerves will need a couple weeks to become fully adjusted to the new crank length, but already from riding 1 hour I can see I have much better pedal stroke, much better power, and I’m actually able to spin better with more power and and higher RPM. I have no problem riding 90-100+RPM with 190mm cranks, in fact it feels much more natural and I’m using my full leg muscle and full potential. I already am seeing 1-3MPH AVG speed increase with similar effort.
13. I can accelerate easier now
14. When I get out of the pedals and accelerate or power over short hills I feel like my bike is responding much better and I’m not wasting energy trying to build speed.
15. There is less pressure on my knees, even when I pedal at a harder slower RPM, I often have slight knee soreness after hard rides through the hills as I have to apply so much more force with 175mm cranks.

16. My feet would often will get hot spots, my feet feel better as the pressure is less now.

17. I can spin better actually with the longer cranks, even though everyone says short cranks are better for spinning, I feel like an airplane propeller with my 190mm cranks I love them! I can not only just spin, but more importantly spin with real POWER.

18. I can accelerate and sprint faster, I can convert more of my leg strength into power because spinning is feels much better to me know with the longer cranks.

19. My pedal stroke and form is much improved from the longer crank

20. I can use my hip flexor i.e pulling muscles on the upstroke when pedaling much more effectively now as I have now 1″ more total length to pull up on my pedal stroke

21. I can maintain my momentum over small hills much better, it’s like I have another gear now I didn’t have before. I don’t slow down like I did before when hitting inclines. Before if I hit even small hills my speed would drop dramatically, my spinning had no power behind it, all I could do is crank really hard in a low RPM and sit back on the saddle to keep my speed up.

22. I’m actually thinking I could handle and might like even longer cranks 195-200mm perhaps

23. I’ll probably get a pair of these cranks for my MTB also in the triple crank format

24. I much prefer the classic square tapper BB Vs the new external BB designs, the BB is much smoother and stronger then the new external BB. Every other ride I would have to tighten the crank arms on the external BB. And I don’t like the exposed tiny little bearings that external BB’s use, I think that external BB are a gimick. What they need to do is take the best of both and combine them, if that’s possible.

- Internet rumors on forums and even “professional” blogs etc. of knee pain and flexibility issues etc. I’ve found at least for me to be totally incorrect as I suspected.

- I did drop my seat down as I expected I would have to do, but I also think I’m going to need to slide my seat forward slighting, and I’m pretty sure I need to drop my bars down by taking out some spacers etc.

25. Overall I will stay this experiment is a great success, I will know for sure in a few weeks of riding and my body adjusting and getting the full power out of the new longer cranks. But just from riding the last couple days I can say that I already notice a very big improvement to my riding, nothing like getting free power and speed, comfort etc. out of thin air! And as I get leaner and in better shape I will be able to tap even more power out of my body with these cranks.

biking etiquette and superstition

Found a link to this news site http://www.npr.org/templates/story/story.php?storyId=9496562 at this post where there was another bike/cyclist conflict. I think I’ve seen examples of both cases of where the driver was at fault and the cyclists was at fault and also where both where at fault in an accident.

I would say that we should defend ourselves, and not instigating fights, if someone just about ran you over, then call the police, get their license plate report them, DO NOT try to act as judge jury and executioner out there on the road, no matter how mad or right you are, or you could find yourself dead or in jail. But  if a crazy driver jumps out of his car and tries to take you out with a tire iron, then by all means take him out first to defend yourself.

There’s a very fine line between defending yourself and starting a fighting and calming a situation down.

10 road cycling safety tips

Good post about post accident review of a cyclist’s accident and a link to 10 road cycling safety tips.

I agree that wearing a helmet is important, but that statistically speaking when someone gets killed by a car they’re usually crushed to death and smashed in ways that not even a motorcycle helmet would have saved them. But in more common typical spills, hitting gravel, another riders tire etc. and just flying into the road, I think a properly worn helmet can help.  So please wear a helmet as head injuries suck, I have a friend with one and it’s very sad thing to have to see happen to a person!

Lance is training and riding as hard as ever!

oakley-lance-armstrong3

Lance had a strong showing at the Tour Down Under yesterday, even surprising himself with his perfomance. I’m so excited to see Lance racing again this season, espepecally since I’m an older rider as well 2 yrs younger then Lance. I read in another article as well that his coach Chris Carmichael had to slow Lance’s training progress down a bit so he doesn’t peak too soon as he was progressing faster then expected. I predict that if Lance does well this year that the average age of retiring cyclists will be extended almost a decade lol, we’ll see though.

I would love to see some power files of Lance to get an idea of what kind of numbers he’s putting out, but I guess that he and his coaches might want to keep that hush hush for now.

Go Lance!

Strength training for cycling, Rambo biker vs. Bill Gates biker

rambo VS. images

There seems to be much debate in the forums, books and studies about the effectiveness of lifting weights and strength training for cyclists or endurance athletes in general. I think one key point that is always ignored is that we are all built differently and everyone has unique strengths and weaknesses that we’re born with and we should  train in a way that is unique to the way we’re built. Also the length of the event we are intending on competing in should have a bearing on how much and what types of strength training you do as well. So both the type and length of events and also your genetics both should play a role in how your unique training plan. It seems like most people want to make things simple black and white, should I lift or should I not lift weights? But the truth is much more complex then that, but yet I see the same question asked over and over online in the forums etc. Do you think that Chris Carmichael would have Lance doing all the strength training they do in the off season if it didn’t work? And I can tell you from documented first hand experience that for me it has made a huge difference in my riding, weight loss, and overall fitness and well being! You have to make an honest assessment of your strengths and weakness and train to improve your weaknesses and further improve your strengths.

Extreme examples of two possible types of riders Rambo rider, and Gates rider and some things to think about

  1. If you’re naturally strong and have powerful muscles, then making them stronger probably won’t help much with cycling unless your focus is short distance events where you can never have enough leg strength. Now on the other hand if you’re built like a sprinter, but want to race in long events like centuries etc. you’ll probably want to focus more on endurance training to help build up your ability to ride for many hours at a time. But I still think that everyone no matter how they’re built should strength train for cycling, you’ll just need to do less of it. Think of the 80/20 rule, you should be riding lots of easy to moderate miles but still having a day or two a week dedicated to intervals and or weight training etc.
  2. A skinny weak legged cyclist that may have plenty of endurance but not much strength or power will want to do the opposite and spend 80% of his time building up the raw strength and power in his or her legs to meet the demands of riding fast, esp. if you’re intending on riding fast for shorter distances where emphasis is on the muscular system.

It’s very surprising that so many “experts” bad mouth strength training for cycling saying it’s not effective, or even that it will slow you down or injury etc. Lifting weights is discredited by many, probably because the “research” that was done was only conducted on trained athletes for a couple months, which is too short a time span to see any major improvement in fact negative improvement probably is what happens in the first weeks of any weight training program as your body is adjusting and you feel sore most of the time. I found that for myself that I was slightly stronger the first month and a bit more a month later, but after a good rest over the Christmas week I was fully recovered and was stronger then ever, and now after another month, now 3 months later I hardly feel sore anymore after lifting weights and I’ve added about 160watts average to my previous average on my 10 minute TT test I do at the beginning and end of each monthly cycle. That’s a huge improvement, but I think that for me having weak legs and realizing it and making it a key point in my training focus is paying off big.

Here are the improvements I’ve noticed for myself from weight and strength training, I say “strength training” as you can strength your legs with body movements and on bike exercises etc.

  1. My recovery time is much faster now, before I’d have sore muscles for days after a hard ride, now I only get sore only if I have a particularly grueling weight session with heavy weights and or high reps or a new exercise.
  2. My running speed is faster, I feel like I have a much stronger stride now when I run, and that I can run faster.
  3. My endurance has improved I don’t tired as easy, and most important my power endurance has improved.
  4. My metabolism is higher, I’m losing weight faster now then just cycling or running alone.
  5. I feel stronger, esp. from squats as they make your whole support system feel strong you can hold yourself up easier you feel more athletic
  6. I also ski in the off season and I’ve noticed that I feel much stronger and have better muscular endurance and don’t have to stop in the middle of the run now, my legs don’t burn as bad.
  7. Injury prevention, by having strong muscles, tendons and ligaments it helps reduce your change of injury
  8. I think that by having legs that are strong and match the strength of your cardio system, your legs can drive your cardio system even harder so that your cardio system can improve even more. If your legs are weak and fail before your cardio system does then you won’t get as good a cardio workout. I notice now that I can feel my heart muscle really working where before it was more like my legs just burned up and I’d have burning legs and an overall feeling of fatigue but not really out of breath, it just seemed to start with the legs and then my whole body was in distress. Now with my stronger legs I can pedal big gears for much longer times and I get the intuition that my cardio system is getting stronger too in an effort to match what my legs can dish out.
  9. They do say that your legs act as a second heart helping blood move around during the contraction of your legs. If that’s the case that would also reinforce perhaps the theoretical advantage of having a high RPM pedaling style of a rider like Lance Armstrong. Perhaps having stronger legs helps push the blood out of your legs better?
  10. I think that from strength training my legs are more powerful meaning the motor units i.e the nerves can fire more synchronize and deliver more force in a shorter time.
  11. I also think that from strength training I’m able to know spin much faster then before, I can get up to 150RPM now where 130RPM was about limit, I felt like my legs where going to just fly off if I went any faster.
  12. I’m sure my sprint has improved now, we’ll see once I start riding outside.

Anyway, it just blows my mind that so many cycling “coaches” tell their riders to avoid weights, here are some common myths I hear

  1. Weight training will make you get huge muscles and add extra weight then that will cause you slow down.
  2. Studies have proven that strength training has no benefit in endurance tests.
  3. Look how skinny pro rider John Doe is
  4. It will make you’re pedaling stroke bad
  5. It will make you rider slower and weaker
  6. There is no benefit from strength training
  7. I’m sure there’s more I haven’ heard or I forget about too

Cheating in cycling training can be good.

I was training hard as usual today but I felt off since I woke up, at the gym the feeling didn’t go away and after a couple sets of weight lifting I felt weak and jittery. I decided to cheat on today’s session and left early. Normally I would not do this but I”m starting to listen to my body and be flexible with my schedule. I mean we’re not robots, somedays we would be better off resting and recovering. I’m sure tomorrow I’ll feel great, so it doesn’t bother me to backup on days when you really feel like you should back off.

I could have pushed through it, but I knew the smart thing to do was to call it a day as I would have probably felt even worse the next day if I dug too far into my reserves on a really off day.

Box step-ups for strong cycling legs!

It’s not often I see someone doing box step-ups in the gym, but I think they’re an excellent exercise in certain training situations. I’m finding them to be really be effective in my muscular endurance phases where I’m doing high reps of 50 reps per set or more,

  1. The focus of strength training in the gym is not to work your cardio system but to inflict as much hurt and burn on your leg’s muscle fibers so they get stronger and bigger and can tolerate more lactic acid etc.  Since the goal in the endurance phase is to do high reps with light or moderate weight, I noticed that with a single leg exercise like box step ups I can work on one leg at a time and put more focus and intensity on it then when squatting or leg press. I also notice that my heart rate goes through the roof when doing high rep sets with dual leg exercises like squats. I felt like the limiting factor in doing more reps is not muscle failure but cardio exhaustion, which isn’t my goal when training my leg muscles. With box step-ups my heart rate still gets up plenty high, but it’s manageable at 85% MHR, and I can do many more reps and get more of a focused burn on my legs. I’m able to do it for a while to the point where the 30lbs dumbbells start getting hard to hold onto.
  2. I can isolate one leg at a time and get it to really burn more then any other way.
  3. I think the movement is much more sports specific training. I think that is important in the endurance phase and during the early and main season that any muscular endurance work tat is done
  4. It feels much less stressful on my knees then lunges, lunges feel weird to do right now, also leg extensions are often times bad for you knees.

As much as I like this excellent single leg exercise, I find that I like using squats and dual leg multi-joint exercises for the hypertrophy and strength phases of my leg training, because it feels safer and more stable with both legs, and I can push more weight all together with both legs then with leg alone. I don’t think it would be smart or safe to do heavy weights with single leg exercises.
