U.K.-based Sphyke offers theft resistant combination locks for wheel skewers, axle locknuts and seat binder bolts.
The QR wheel skewer locknut or axle nut is encased in astainless steel shielding with a four-digit customizable combo lock. A waterproof plastic dustcap is then placed over the lock. Axle nuts for varying rear wheel hubs are available, including models for internal gear and fixed gear hubs. A similar system is available for the seatpost binder, with a three-digit combination lock.
Sphyke is selling its products via its U.K.-based website and through select shops, primarily in London and Berlin. The company has not yet appointed a distributor for the U.S. market but after several years of product development, a company spokesman said it now has the production capacity to expand to more markets worldwide.
