Cranks 175/165 and pedal strike

Cranks 175/165 and pedal strike

Been fiding a conversion (my first) for about 6 months and have been getting more aggressive
in my riding. Harder turns, more lean, etc.

Having tagged my pedals on the ground on a few occasions, I wanted to solicit a few
opinions: in terms of that type of pedal strike (no problem with the front wheel) will there be
a significant difference if I move to 165 cranks? Should I just watch my turns more?

If you have 175's you are cutting a full cm off your crank arm. Measure that. If you wanted to try it, you could look into some pedals that arent as wide, though if it has been a problem on multiple occasions 165's might be the way to go. Out of curiosity, what pedals are you using?

Changing to shorter cranks will help a little. Changing to lower profile pedals or clipless will help a lot.

I rode 170mm cranks for many years on all sorts of conversions and track bikes. After the first year or so I hardly ever clipped a pedal. I rode 165's for a few months and really didn't like them.

Also, as you ride more you'll get a better at cornering. You'll start to see the lines you can take without scraping a pedal.

Many thanks

Thanks for all the quick replies.

Kind of a duh, but I didn't even think of the pedal profile. Currently running MKS Sylvans with
cages. Don't want to go clipless just yet, but do you have any recommendations on a narrower
profile pedal?

the sylvans are pretty small as far as pedals with clips goes.
GR9's might be a bit slimmer, though I dont know for sure.

You could try the MKS Stream, and MKS also makes a track version of the Sylvan without the U-shaped cage, which probably cuts about a centimeter or so off the width.

I run the GR9, which seem to be pretty popular. They're narrower as well.

I crashed into a curb today due to pedal clip (and racing a red light), and I was about to ask this question. I'll be ordering some GR-9s soon... my cranks are already 170s.

It will help a bit, but there is no getting around the fact that road bikes (and thus conversions) have pretty low bottom brackets.

I know getting a new frame may be out of the question, but getting something with a high BB is about the only way to really get rid of pedal strike issues.

I think that MKS Sylvans are about the most narrow cage pedal around.

When you're ready for clipless, look into Speedplays. They corner like nothing else in the world.

Big win for the forum here... again many thanks to ya'lls...

Been running a conversion here in Hiroshima as my first fixed gear; a trial run if you will.
Love it to death and will more than likely purchase a proper frame (not necessarily "track")
in the near future.

Wouldn't have thought about BB height, etc. in the past, but it appears I have a few new
factors to consider. Thanks much!

For what it's worth, on my conversion([peugeot) with 165mm cranks i clipped the actual crankarm somehow once, and the pedals once or twice.

on my pista with 170mm cranks, I've yet to clip.

this could be because the bb is higher, because i'm a better rider than i was before, or both.
