Cranks for an 2005 Norco 125?

[DJninja]

Basically what Im wanting to know is-
How do I know what measurement(mm) my new cranks and bb should be?

What length is most common more people doing dirt jump, street and some freeride?

Will I need a new bottom bracket?

The cranks that I currently have on my 125 are Raceface ride xc cranks and I am wanting to change to saints(well I have no choice because I recked the raceface).

CRANKS/CHAINGUIDE: Truvativ Hussefelt single 36T ring , ISIS GIGA DH spline BB, Truvativ box guide chainguide

This is what I got of the norco website, Im not sure If i've got the same bb still. Will have have to take it apart and look at what it says on the bb?

Thanks in advance

do a search, you might get some answers but i am guessing the width of the bottom bracket would be 68 mm i think...not sure, look on the norco website at the geo for the 125

if you still dunno just take it to a shop i say

The stock norco 125 has a 68mm bottom bracket shell and 175mm cranks.

get cro mo's ninja, better for sheer strength... cheaper. you mostly do dirt jumps anyway.

7005 aluminum frame, slotted rear dropouts, 24/26” V-brake mounts, & a Euro bottom bracket

+ 68mm as already mentioned...

Saints are really good forks but are fairly pricey, if you don't have the dosh you might want to look at Holzfellers or cromo BMX styled cranks.

As for what length ... I'd say 170 mm, but 175 mm should be fine as well. If you do quite a bit of DH or Freeride then maybe even 160 mm.
