Surly is introducing a new bike model for 2014 called the "Straggler". It is mostly a disc-brake version of the Cross Check.
For some reason I have been thinking about it as a possibility for a 650b build, mounting Hetres, and using it for distance rides and randonneuring.
As it's a Surly, tire clearances are already more than generous for a 42mm tire. And as it is set up for disc brakes, no rim mismatch issues for braking in a 650b conversion. The rear dropouts are set for a 135mm axle, so wheel options are good from the current and growing "27 1/2" enthusiasm in the mountain biking world. The bottom bracket height of the Straggler would also seem to be favorable.
The frame and fork are loaded with mounting braze-ons. Setting it up with whatever fenders, racks, and lighting should be a piece of cake.
It comes in a glittery purple finish. Some folks have said this model should be named "Sparkle Pony". I like that idea, too.
Anyway, I'm wondering if anyone else has any thoughts about such a project, both pro and con. Is there anything I'm missing?
