- 68/73mm BB fitting
If you aren’t running any other BB mounted chain devices or mechs, then for a 68mm shell you need one spacer non drive side, and two spacers drive side. It should have come with three. If it was new get back to the seller, if it was secondhand send me your address and I’ll get some off to you in the the post.Posted 4 years ago
Or, having just re-read your post, are you fitting it in a 73mm shell? in which case you just need the one spacer drive side, unless you have a BB mounted device.orangeboyMember
SRAM / truvativ Isis bbs used to come with just one spacer and would fit 68/73 mm shells
The three spacers is for ht2 not gxp or Isis
And yes despite what’s above the same bb was and is sold as being for both shell widths despite only having one spacer
Just don’t bottom the left hand cup onto the frame, it may have a rubber o ring to try and stop you going to far anywayPosted 4 years ago
