    So here we are back for another quick update on the worlds lightest Pro XL bmx bike.  Last post covered the hubs, this time we’ll keep going with some more of the wheel components.

    First off we have some rims that Velocity made for us using their A23 extrusion.  Not terribly expensive at around $90 per rim, which is really quite affordable for a one off.  This set came in at a very consistent 282 grams each for a 32 hole version.

    Mated to that will be some Tioga Powerband and Powerblock tires.  The front 1.85 came in right at claimed weight but the rear 1.75 was a portly 20 grams over claimed weight.  Still not considered heavy by any means.

    Filling the tire will be some special tubes from Switzerland.  Made by Eclipse these are the by far the lightest option for a tube, but at $68 per tube they are actually more expensive than the kevlar based tires that will wrap them.  At 40 grams per tube though, the rotational weight savings is hard to pass up at any cost.

    Added to the rear hub we also have the titanium 13t cog from Recon, Kcnc spacer kit, Parts of Passion lockring, and Control Tech titanium bolt on kit.

    Coming soon, the custom made spokes and more of the components.  We also begin fabrication of the custom frame in a couple weeks when NAHBS is over.
