If you have an Otso frame that is begging to be run as a singlespeed, then look no further. Wolf Tooth and Otso are within the same umbrella company, so it was easy for the two brands to work together on tricked out hardware kits to convert their popular frames. These kits are available in post and flat mounts, with instructions on Otso’s blog. Both the flat-mount and post-mount kits are $94.95 and shipping now from Otso.
