Bottom Bracket Question

Recommended Posts

As a rule theres 4 main types of fine spline 3-piece spindles that are all cross compatible, so unless you're cranks use a pinch bolt, they should fit be either a 19mm 36 or 48 spline, or 22mm 36 or 48 spline. lengths up to you and how much spaceing you want to put on.

the DMR spindle looks like a 36 spline, and if Kierons rite they will be a 19mm, If you have a look at your cranks you should be able to measure the spindle diamiter (don't need to be exact, it'll either be 19mm or 22mm) and count the splines (Y) . Then once you know what size/spline number spindle you're looking for you can start properly looking.

If you wanna double check the size of that DMR spindle give CRC a call or e-mail, there all friendly guys there!

The DMR axle IS 36 spline, 19mm (Running two pair of those cranks ;) ), so if you find out (should say on the axle itself for the spline nimber at least) what the other's need, you should be able to sort something out

Hope you sort it, hate drivetrain problems!

just took it off..... joesnt say jack f**k on the axle :angry: stupid f**k gonna have to sit and count now.

I'm failry sure that profiles are 48 tooth.

spoke to the guys at planet x uk and they told me the 19mm profile one fits.... that dont mean much to me as i dont know much about them.... but i can order a dmr one right now if i know it will fit.

EDIT: profile one it is. dmr just emailed me telling me the axle is a 20mm not 19mm :(

thanks for all the help from you guys!
