I like that, apart from the high-rise stem looking a bit goofy (would of gone for a 0º myself). How did you mount a rear disc brake btw?
It's a Hope Hydro universal mount: One caliper half has an extension on it that clamps to the rear dropout. The clamp forms a secondary dropout, and the shortened axle of a special Hope Ti hub fits into it. You then put a skewer through the lot. It needs something to prevent the whole thing turning around the axle centreline, hence the torque rod. Works very well.
The stem does indeed look rubbish. IIRC it was a combination of the steerer tube for the RC-35's not being long enough for spacers and the missus having long legs. Having said that, given the choice, I'd go for a goofy stem over shorter wife legs any day of the week.
On yep...there's a bonus CogHog in the pic below!
