i screwed up my cranks and am replacing them with truvativ hussefelts, my tech said i need 68/115 cranks, the howitzer bb comes in the 68 mm width but does not have the spindle width measurement it only has the 51 or 56mm chainline measurement, how do i pick which BB i want?

if you double the chainline length does that give you spindle length?

Should be the 51mm chainline version of the Howitzer.

for future reference and my own knowledge, how do you know?

search for 'chainline' under my user name....should be a bit of reading for ya...

davep, thanks alot, front what i can deduce i need the 51mm

 

[TWeerts]

51mm chainline = 135mm rear hub

56mm chainline = 150mm rear hub

 

[DirtyMike]

51mm chainline = 135mm rear hub

56mm chainline = 150mm rear hub

Thats pretty much it.

Do yourself a favor, get the team. The xr tends to wear really fast, I have been beating on the team for quite some time.

Are you installing this yourself? If so, make sure you read the spacer setup for a 68MM shell. Its the same bb for 68 or 73, and because the spindle is still in teh BB, you really want to make sure you get the spacers correct.

Should be two on the drive side, one on the non for 68MM , if using a BB mounted chain device, replace one spacer from the drive side with the chain device.

My brother and I did the same **** so he could run 83mm cranks, instead of beign stuck with either oldschool isis, Which is hte BB that came with the bike, or truvativ Howitzer.....Beyond rediculous the amount of shavings left on the floor.
