  • whats the weight with BB?

  • Does this fit a 83mm bottom bracket

  • XX is good. but ill stick with my XT and XTR components

  • is sram x7 good crank

  • X-Glide is where the difference is at. '11 XO feels rough in comparison. I'd take XTR or even SLX over XO in terms of shifting performance, but the XX cassette and chainrings really outdoes everything I've ever ridden. If the SRAM 2x10 Experience demo team comes within 200 miles of you, I'd definitely recommend investing a trip out there and ride some high end bikes, unless you don't want to feel compelled to upgrade.

  • @ccmeaston, I'd suggest you go for a test ride and see if you can discern the play from the saddle. If not, have a great season. If so, feel free to send it all back and we'll go another route.

  • @ccmeaston, that should be unnecessary. The ID of the left side bearing is 22mm, the same as the stepped down portion of the spindle there.As long as you've torqued the left side to spec, you've installed it correctly. As I mentioned before, there may be a few thousandths gap in the right side bearing/spindle interface, and that is normal. So unlike bottom bracket designs of old, this minute wobble you feel when yanking on the pedal end of the crankarms is nothing to be concerned with, really.

  • i'm almost tempted to go the the hardware store and buy a tin strip and fabricate a small collar to eliminate the spindle-bearing race gap...

  • yes, when i grab the crankset center on its driveside face and try to pull it east-west, there is no east-west play. but when i grab the arms on its pedal ends and move it opposingly, there is that slight wobble. i pulled off the left crankarm and noticed that the splined teeth of the spindle isnt sitting flush on the bearing race - in fact there is about a 1mm gap all around - which i believe you mention below. this gap looks to be, from my view, where the wobble is originating from.

  • @ccmeaston, Double check that you don't have any axial movement. You should not be able to push or pull the crankset sideways through the bearings at all. If this is the case, your left side crankarm is not installed correctly. If there's no movement through the bearings you're in good shape.
