Funny thing, the frame on the picture is 5 years old. CHain goes throught the frame too, the BB is about +8.....At that time, everybody thought it was ridiculous to ride. So do everyone eversince, because you need a 30 tooth sprocket in the front for a proper chainline(
I might build it up without chain, if you wanna see some pics.
Monty looks amziing. True innovation
