Prestacycle Uniblock Cassettes

Prestacycle UniBlock Cassettes are a single-piece unit 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. ChroMoly alloyed steel is significantly stronger than materials used in other Cassettes including top-end OEM Cassettes.   UniBlock will last longer than standard steel cassettes.  The single block design offers 3D structure to optimize strength and distribute forces.  This allows Prestacycle to remove more unnecessary material, making our cassettes lighter than even top Manufacturer models that use fast-wearing aluminum big cogs.

Better Engagement, Smoother Operation

Single block design insures the freehub has MORE engagement no matter what gear your are in.  Single cogs from other Cassettes can cut-like-a-knife into freehubs.  By increasing and distributing engagement across the entire freehub in any gear, we are reducing torsional loads thus reducing freehub wear and insuring lowest rolling resistance within the freehub.  This also makes our Cassettes the safest to use with high-end alloy freehubs.  Without any spacers in UniBlock, there is nothing to loose, and nothing you can install incorrectly. Faster cleaning on and off the bike, with quicker, mistake-free installation insures you are ready-to-go!

HG11 Profile – also fits HG10 wheels with our optional lockring

UniBlock Pro Design enhancements also allow adapting newer standards to old, such as adding 11 & 12 speed to Shimano 10 speed wheels (with our optional lockring), or adding a shifting system to a wheelset or direct drive trainer that does not otherwise support that drivetrain.
