rear hubs are "fixed" threaded on both sides. You can use a cog and lock ring or a freewheel on either or both sides. The rear hubs come spaced at 120mm, but include spacers to make them 126mm, 130mm, or 136mm. The front hubs are spaced at the standard 100mm.
Velo Orange high/low rear hub is a four bearing design with the same quality of Japanese bearings as the Grand Cru hubs. I just can't see how saving $20 by using cheap hub bearings makes any sense. The alloy cassette body has three large pawls and is well sealed. As with the Grand Cru high flange touring hubs, they can be disassembled without tools for cleaning or service. VO internal-cam quick releases are included. This is a great hub for those who want a lighter and slightly less expensive hub than the Grand Cru Touring hub, yet with bearings typically speced in hubs that cost twice as much. they would be great on a fast rando build, classic race bike, or pass hunter.
Velo Orange low flange front hub is a good match for the high/low. It also has Japanese bearings and includes a VO internal-cam quick release.
as a set, which saves you a few dollars.
The Grand Cru high flange touring hubs have been delayed by a few days, but will be here soon.
We'll be building wheels based on these hubs and our rims soon. Are there any particular combinations you'd like to see?
