Prestacycle UniBlock Cassettes Cassettes are a single-piece unit exquisitely machined from a solid block of cold-forged Chrome Molybdenum alloy steel, then heat-treated, tumble-finished and electroplated for added durability and low-friction operation. They last longer than standard steel cassettes.
Single block design allows Prestacycle to remove more unnecessary material, making our cassettes lighter than even top Manufacturer models that use fast-wearing aluminum big cogs. Without spacers, there is nothing to loose. Faster cleaning on and off the bike, with quicker, mistake-free installation insures you are ready-to-go!
Prestacyle’s neutrality allows you to get one manufacturer’s Cog spacing onto another manufacturer’s freehub. No need to waste money to convert wheels to different freehub standard.
Design enhancements also allow adapting newer standards to old, such as adding 11 & 12 speed to Shimano 10 speed wheels, or adding a shifting system to a wheelset or Trainer that does not otherwise support that system.
