The Park Tool SS15C is designed and built especially for single speed bikes, a forged multi purpose ride saver. Combining a 15mm socket for axle nuts, 15mm open end spanner for pedals, the tool also doubles up as a tyre lever and bottle opener. Just the right size and length (17cm/7") to take along or to wrench in the garage, the "SS" is destined to be a single speeders favourite.
