[Closed] Orange 5 / Middleburn question

Not sure about the BB length, but it'll be a 73mm shell, and probably around a 110-113mm axle (that's just a guess though). The mech will be a top pull 31.8mm clamp, and will need to be a top-swing jobby. No space for a conventional.

73mm shell, and 113mm axle is what I use, and what Middleburn recommended, however this was for a 47.5 chainline, the fashion for big tyres(and clearance needed)now dictates a 50mm chainline, so if you have a recent front mech you may struggle getting into the granny ring on the narrower chainline.

Thanks very much guys
