After a few months of running his Stumpy hardtail as a singlespeed, Josh decided to tinker with his Hope hub and turn it into a 6 speed. He ran an Ultegra 10 speed cassette broken down into a 13-21 I think, with a Tiagra road derailleur and a DMR chainguide up front.
The verdict? "Neither here nor there." The fact that you are shifting but not really getting much mechanical gain through such a small selection of gears rendered the experiment a big 'F', and the little vegetarian was seen sporting a full complement of cogs at Makara last night. Top marks for effort and wasting time and money though.
