Had some spare parts in my parts box, so I decided to turn my 2007 Catrike Speed into an "R Spec" trike. The Catrike R Spec option consists of a SRAM "Rival" 10-speed group - compact crank, TT 500 bar end shifters, front derailleur, chain, rear derailleur, and 11-32 cassette.
Finished the conversion late this afternoon and rode to WRL to test the trike out. The R Spec group is the same group as installed on a stock Musashi. The stock Musashi is the best shifting bike I've ridden, and the trike performed equally well. Climbed Flag Pole Hill at 6 mph in the 34/32 combination (27.6 gear inches). Experienced moderate leg discomfort and was a little out of breath when I topped the hill. I wouldn't ride Lancaster or Muenster with this gearing, however, it is perfect for WRL. Got the trike up to 26.7 mph in the 50/11 combo and had plenty of gear left.
Why did I do this? Because, I had run out of projects. Now I'm out of projects, again..........
