Longer crank length advice(3 posts)

Longer crank length advicetao

I noticed some micro cracks near the spindle on my Ultegra cranks, a perfect excuse to buy the $150 Dura-Ace cranks from Performance in addition to the always present more size selection issue. So I went with 180mm, used to have 175s, I'm 190cm (6'3") with a longer than average inseam. Besides the obvious fit adjustments, I can finally get rid of that pesky 5mm spacer, and taking it easy for the first 500 miles or so for my knees to adjust, any other major recommendations or gotchas?

I know, I know, but I've only been riding seriously for two years and keep a high cadence (90 - 105 flat, 80 - 95 hills) but I see guys that are 5'10" spinning 75s and it just seems that being able to apply force for a longer period, especially when you're able to spin them, is a good thing. Maybe it'll just hurt me knees after a month and I'll crawl back to 75s. Anybody else try this? Am I just stupid?

You will be fine. Last year I finally went to 180's on all bikes (road, ATB, TT). Before that I used 175's on the road bike but never felt comfortable with the longer cranks on the other two. Now that they are all the same it is great. @ 6'3" you are fine.
Watch your seat height, split diff. 2.5mm lower maybe. nmSpunout
