This is the latest edition of this bike. I started building these in 2006- I can't say that I have made very many of them but I am always keen to try to make them have better features. This one has the Shimano Alfine-11 parts group with hydraulic disc brakes. The rims are Stan's but I did not set it up tubeless. This one takes up to 700x40 tires......actually it might even fit 45's. The Brooks saddle is a must along with the headlamp which is run by the front dynamo hub.
