Lighter, Simpler, And More Compatible

Prestacycle UniBlock 11 Speed 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 lose. Faster cleaning on and off the bike, with quicker, mistake-free installation ensures 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 standards.

Design enhancements also allow reverse-compability, such as adding 11 & 12 speed to 10 speed wheels, or adding a shifting system to a wheelset or trainer that does not otherwise support that system.

Bought this to use with Campy EPS (11s) and non-Campy freehub wheel. Cassette range also outside Campy spec (11-28)...but it all works like a charm! Excellent, fast, no stumble shifting, only minor rear derailleur adjustment, 2 minutes, ready to ride. Durability with waxed chain TBD.

I am able to stay in the big chainring on all but the steepest grades. Kinda expensive but expect longer life.

A new state of the art

I cycle ~12K miles per year (and have for decades). Bike is Trek Madone with Campy EPS 11-spd drivetrain. Have used both Campy Record and Shimano Dura-Ace cassettes and chains. Most noticable, and much to my surprise, the PrestaCycle cassette is stiffer than the competition. Shifting is more precise (presumably because the spacing between cogs is precisely engineered), and contrary to some review claims, it is quiet. In short, the PrestaCycle cassette is an amazing piece of metallurgy and design that sets a new standard in a number of categories.I encourage you to try one.
