My shop has one of the new Hyland Civia bikes sitting in the window, and I have to say that it is one clever commuter.
The frame is aluminium with sliding, modular drop-outs and 135mm spacing. The sliding portion also mounts the fender mount (but not the rack mount) and has provision for a post mount disc brake (easier aligning of the caliper). The fork is carbon fiber with a post mount caliper mount as well.
The frame thus can easily mount a standard hub, a Shimano or SRAM internal hub, or the famed Rohloff 14-speed internal hub. Be prepared to pay…the Shimno Alfine equipped model seen here should just squeak under $2k. Expensive? Yes, but the component spec is absolutely first quality.
The hydraulic disc brakes and metal fenders are standouts.
You can also buy the frame/fork/dropout set for a little over a thousand bucks.
