MTB sizing - Reach & stack?

Postby Jean » Mon Nov 15, 2010 12:44 pm


Looking intoa Ragley Blue Pig frame their website makes some mention of a supposedly new system of frame sizing, 'reach & stack', which is linked to here. I've never come across it before but it seems reasonable enough for freeride or downhill bikes. Don't know if it is of much use to XC or trail bikes. Oddly, if you go to the Turner webpage from the one above, its sizing FAQ is all about top tube length, but if you go to their bikes specs they seem to make use of it. Transition Bikes, as linked, seem to use it too.

Anyone seen it before? Comments?

I think you've got the idea. It references directly to the BB instead of referencing indirectly via the saddle.

You'd really have to take in to account seat tube angle when comparing reaches. This is true of horizontal top tube measurements aswell anyway. I really like the stack measurement.
