Lasco’s Machined 11-Speed Cassettes Work on 10-Speed Hubs

I wish I saw this product earlier! If you’re like me, you’ve got a few wheelsets lying around that are 10, not 11-speed compatible. Even selling these wheels in a largely dominated 11-speed market was more difficult than I imaged. Lasco Concept has engineered a solution to this common problem, by machining 1.85mm off 10-speed cassettes, allowing for 11-speed use. Right now, they have the following sizes available (Shimano Ultegra: 11-25 | 12-25 | 11-28
Sram Force : 11-25 | 11-28 | 11-32) and they’ll even convert any cassette. See more at Lasco Concept.
