just had a mate round asking me to fit an e13 DRS dual rin chain device (bb or ISCG mount) to his 2010 carbon stumpjumper, which in addition to lots of carbon weave and shiny white bits, also features a press fit shimano BB with an XT crank in it.

So it won't go on, as there are no chainguide tabs and no way of securing the backplate against the frame with the bottom bracket cups as you would with a HT2 arrangment.

Which got me wondering if anyone already does or is in the process of developing a way of mounting a chainguide to press fit bb's. Particularly with so many folk going single ring plus 10 speed 11-36 cassette and minimalist 'xc' chainguide: presumably you won't be able to put a single ring xc guide on any of the current press fit bb frames?

Any solutions out there?
