Rode 180 XTR 952's for a season and a half and didn't like them at all. I found the 180's difficult to spin and the leverage I got from them didn't seem to be that much greater than the 175's.aosty said:
do it Al...aosty said:Okay, thanks guys. I have pretty much the same issues... particularly spinning fast (I often ride pavement to the trail now) and tagging rocks often.... gonna downgrade to 175 and see....
Cause I buggered up two sets of 180 cranks and had no choice. I'd go back to 180's in a second if I could find some that didn't cost so damn much. I just climbed better w/ the 180's. Call it mental or whatever, I can really tell the difference.aosty said:
Aosty, your a tall guy like ~martini~ and me. I do notice a very definite difference in climbing with 180s over 175 and use 180 esclusively on my single speed bikes - except for my fixed road bike which I use 175 (and am considering 172.5). I also feel like I can spin 180s out pretty good.~martini~ said:I had been riding 180's for a few years on my 26" SS, and thought I'd try 175's when I got my 29". I wasn't expecting much of a difference, maybe easier to spin or a tad less leverage. What I did find out is that my knees hurt like hell riding the 175's. I tried moving the cleats around a bit and that only made it worse. I ended up losing my shorts on the 175 cranks when I moved back to 180's. Now I hoard 180 cranks. Got three sets now. I won't ride anything but 180's on mtbs. The slower cadence works for me there.
Conversely, I tried 180's on my CX bike and hated 'em immediately. Knees hurt there too. I put 175's back on and everything was hunky-dory. Still using 175's on my fixie too. FWIW, my inseam is 35". Not too long.
