SRAM Rival 1x11
At least with respect to using the Change Bike as a stand in road bike, I do think its quite capable.
I did feel that the heavier wheels (disc brakes + 42mm tires + tubes )meant that I took a hit with top end speed wrt my TT bike. But thats why its a stand in rather than the best tool for the job.
Conversely, when the fold is needed for transportation or when the roads give way to a unpaved track, no 'best tool for the road' road bike will make it.
For the Desaru ride, I was always in the front few of the pack, being one of the 3-4 folks taking the pulls, so I guess that does count as a sort of practical proof that its going ok for the bike and setup.
I also got 28mm tires as well as a rear rack coming in soon, so I'll write about them in future posts.
