crank length

I had always used 170mm and never considered any other length. When I bought my new Cube back in January, it came with 172.5mm which seems to be industry standard fitment these days :?

I have been using the Cube all summer(sic) and always felt a little uncomfortable but not enough to be bothered to find out why . Due to a mechanical warranty issue, I have only the winter bike right now. This sports 170mm cranks and its so comfortable! :shock: . Despite being nearly 2Kgs heavier, it feels just right.

So I guess I should get 170mm crankset for the Cube? I am 5'8" and have 31.5" inside leg.

Is everything else about your position on the Cube exactly the same as your other bike? There are plenty of reasons why you could be less comfortable.

I have bikes with everything from a 170 to a 175mm crank. I can't say I've ever noticed any difference while pedalling.

However, I've also got 6 different saddles and can't tell the difference between them so maybe I'm just numb.

Have you actually picked up a ruler and looked at 2.5mm? It's tiny.

The differences between your two bikes are much more significant than the 2.5mm difference in crank length... unless both frames are the same with identical saddles with same seat post length exposed and the same fore-aft position, with the same pedals, cleats, shoes, padded shorts etc etc.

From what I've read (Andrew Coggan, a Univ. Utah presentation) it makes no real difference anyway. Spend your money on a proper bike fit instead.
