Reign X Crank Length
Are any of you running 165mm cranks? If you are, can you remember the benefit or loss from previous cranks.
I've ridden 165's on an Iron Horse Sunday and then jumped right back on my Reign X with 170's and I can't tell a difference in crank length. It's about 1/4 inch if I'm thinking right. But for me I can't tell a difference, riding the same trail, just on a different bike. I'll give you that they're very different, but I can't tell a crank difference one way or the other.
you can tell a difference, but personally I've just desensitized myself to it. 180mm on the XC bike, 175 on the reignX, 170 on the DJ, 165 on the BMX for some reason.
there is a notable difference between 180 and 170 in terms of mashing potential, but you get used to it one way or another quite quickly (as in a few minutes into any given ride)
