Cranks question(8 posts)

Cranks questionSS_Billy
Sep 5, 2001 5:50 AM
For a 5'6" guy with a 33" inseam, is 175mm too long? I am using fixed gear (42x15). I have a sloppy spin at high speeds and nearly wrecked yesterday as a result of it...scared the sh*t out of me! I was going down a hill at 38mph, spinning like a madman and hit a nasty bump in the asphalt in the bike lane...freakin' San Diego roads. Should I go to 170mm? Where can I go to find a set of 170mm square taper cranks for about $30-$50?
Thanks guys?

Shorter is always better for spinning. Many use 165s for FG training. At 5'6", 175 is correct length for mtn bike cranks; most road bikes in your size would come with 170s. All personal taste, of course. Check with LBS's "take off" or old parts box, Ebay, or online classifieds for cheap used stuff. Yer welcome?

I have a set of used 105s that I will place on ebay tomorrow. They work great but are very scratch from a lot of use. They should go for pretty cheap since no one uses squred taper anymore. Let me know if youa re interested and I'll give you the ebay item number once I place the add. cheers. Nestor
Another benefit of shorter cranks...MrCelloBoy

on your FG is increased cornering clearance. I'd say 170's at least. Maybe 165's.
Not sure about sources. Try Loose Screws.

Excel has some Stronglight "Ironlight" cranks in the 170mm length for $48.00. Look VERY nice.

Thanks for the info about the Ironlights, I ordered a pair. That was the best deal I could find. I had my eye on a used set of 105s on ebay, but some last minute bidder beat me by $1

I agree that it is a matter of personal taste. There are factual benefits as a result of physics...already mentioned are that short cranks are easier to spin and have better ground clearance. I'll add that longer cranks allow the cyclist to exert more power to the pedals. If you've got powerful legs and love gear mashing (as I do) then longer cranks might suit you.

If you are JRA on the FG, get whatever you feel comfortable with. If you are trying to specifically work on your spin, go for 170s or 165s.
