I can confirm that two bottles fit quite well in a large FM936 frame!  Also got a couple other 3D printed bits, the Manitou Mara remote lockout exits on the top (or bottom in the case of this mounting) but there's no room in the frame, so I printed a little sleeve for the aircan with a mount for the cable housing, so it now exits out the non-drive-side.  I just swapped from an LCFS911 to this and carried most of the parts over, but still going to build a new wheelset and get new handlebar/stem.  Once it's all done I'm thinking it'll come in right under 25 lbs.  The trails will be wet until mid March or so, so it'll be a while until a ride report.  So far the geo feels a lot like my Guerrilla Gravity, except it's fast in a straight line like my 911 was.

Sorry to bring up such an old post. I was curious if you had any more info on how you got the Mara to work with a remote lockout on your frame. I have a Vitus Rapide FS with a Mara and absolutely love it. I do wish I could run a remote to firm up the platform on the fly though. I tried to PM you, but I don't have any posts so it may not have went through.

Thanks,
Jake
