Velocite Gram triplet (2:1) straight pull rim brake road hubs.
Velocite Gram straight pull road bike hubs feature the widest rear flange spacing in the market. This configuration is made possible by the triplet (2:1) spoke lacing pattern. The oversize 69xx series bearings ensure smooth running out on the road, not just in your hand.
These hubs are a result of our quest to manufacture the hubs that would satisfy our product philosophy of absolute performance.
The design is deceptively simple with the minimum of parts and no spurious complications such as preload adjustment which is mechanically not desirable for cartridge bearings, nor is it useful. There are also no shims, spacers or odd bearing sizes that would complicate or prevent the easy maintenance of the hubs to prepare them for the race day.
Gram hubs are designed to offer the best possible real world performance, especially for stronger riders as they benefit the most from the more durable bearings and the ability to make torsionally stiff wheels.
The torsional stiffness is derived from the stiffness of the cold forged alloy hub shells, and from the extra wide flange spacing. In fact at 68mm non-drive side to drive side (hole to hole) Gram rear hub has the widest flange spacing of any hub currently in the market.
Maintenance of the hub is very simple, requiring just two Allen keys (number 5 and 8). Even the axle is removable by hand, permitting frequent and thorough cleaning to keep the hubs operating at their peak performance.
To ensure optimal ratchet engagement ensure that you use light grease as heavy grease can cause pawls to remain stuck in their seats.
