have recently bought a nrs 1 2005 as a project rebuild. bike is complete now but having problem with bb. went on website but can't find correct size. installed a 122mm, to big. changed it to a 115mm and seems better, but im still get contact with my front dérailleur, doesn't matter how much i tweak adjustments.

can anybody tell me the correct bb bracket size. [/b]

    well it all depends on what the cranks are.

    Make and model and year. (cranks).

    well for a 50mm chain line you need a 113mm axle if it is the FC-M410-L

    if it is the FC-M411-L then you need a 123mm

    and if the FC-M410-8-L you need a 118mm

    all give a 50mm front chain line.
