Q: What is the outside and inside dimensions of the No Tubes Alpha please? I need a wider-than-open-pro 28h rim.

Just a quick post about converting the popular Velocity A23 rims to run them tubeless for cyclocross or road since we've been experimenting today. The A23 has a smooth curved inside wall and converts pretty easily to tubeless with the correct products. All products mentioned below are available in our shop.
Cyclocross tyres
We fitted a Hutchinson Piranha (tubeless ready) with just the NoTubes yellow tape and a 44mm Universal valve stem. The tyre was pretty tight and needed careful use (not damaging the yellow tape) of tyre levers to get the tyre on. It inlated immediately using a standard track pump.
Then we tried a standard Maxxis Raze 700x33C. It went on very easily, too easily in fact with just the yellow tape, and burped easily. We fitted the Cyclocross rimstrip and it inflated a lot easier, either with some vigorous pumping from a normal track pump, or very easily with a compressor. In use it may need a layer of 17mm Velox tape under the rimstrip; we'll find out soon and add to this page.
Road Tubeless
To be confirmed, but since the Hutchinson cyclocross tyre inflated easily, the road tubeless tyres should too using just the yellow tape and 44mm valve stem...[ continue reading >> ]

Our rim range continues to grow with some new road and mountain bike products in from Salsa and Velocity.
Salsa Delgado
The Delgado is available in 26" and 29er size, with the 29er costing £39.99 per rim and the 26" £59.99 for reasons we don't understand! It comes with a cool chilli sticker.

Velocity P35
The P35 is designed by "650b guru" and all-round bike inventor Kirk Pacenti so they are bound to be a bit different, and at 35mm wide they are large. Our build here shows them on a customers front hub from a Jones Spaceframe, at 135mm wide they are the same as most rear hubs.
The idea is that a super-wide rim expands the tyre more than normal so you get more traction, and you can run lower pressures making the tyre mould over bumps better - more comfort and less rolling resistance. More on the P35 rim here >
Velocity A23
More rims from Velocity expand our 700c range and the A23 has already been popular in the short time we've stocked it. Wide-ish for a road rim at 23mm gives the tyre a bigger footprint and smoother more comfortable ride, with the potential to...[ continue reading >> ]
