The team made it down to the USGP at the 2013 worlds course and we all loved it. Tim and I raced both days and Amanda did Sat, while Will raced Sunday. I waited too long to pre register and didn't want to race with 150 cat 2/3's, so i raced Single Speed. I thought i'd post a few pics of my Celtic Cross before i return it to geared form.
I only had to use a spacer set and a 22 tooth cog. My Celtic Cross has semi horizontal drop out so chain tension was achieved pretty easily by just tightening the wheel in the right place.
