Velocity A23 Polished Rims, Velocity Race Hubs, Gunnar Roadie Project Bike

These polished Velocity A23 rims and Velocity Race Hubs will become the wheels for the  Gunnar Roadie Project Bike.
 Velocity offers many great looking finishes on their rims. The A23 is a fairly new offering for them. This rim is slightly wider, 23mm width, than rims produced for road bikes in recent years. The wider width works with a 23 mm tire to decrease the aero-dynamic drag of the tire and wheel combination. Better support for the tire side wall is also a benefit of the wider width. The better side wall support lowers the rolling resistance of tires by reducing the deformation of the tire side wall while riding and also adds better grip while cornering. Velocity rims are manufactured in Florida, USA. They have teamed up with a local polisher to offer the polished finish on their A23 and Deep V rims. The finish on these rims looks like chrome. 
Velocity A23 information:

Size: 700c (622)

Velocity race hubs have sealed bearings and offset "hi-lo" flanges. The flanges are designed to help equal out the spoke tension on the drive and non drive side of bicycle wheels. They are available in a black or bright silver anodized finish. The Gunnar Roadie wheels are built with the silver finish. The front Race hub is available in 20,24 and 28 holes at a weight of 80 grams. The rear Race hub is available in 24, 28 and 32 holes at a weight of 255 grams.

The wheels for the Gunnar Roadie Project Bike built with Velocity A23 rims and Velocity Race hubs ended up weighing 1,590 grams. This is a good weight for this conservatively built wheelset. These wheels are laced up with 28 double butted stainless steel spokes in a 2 cross pattern in each wheel. They do feature Wheelsmith alloy spoke nipples in a anodized blue finish. 

Custom built wheels are just what the name says; custom. You can specify the build anyway you want. Build them yourself or have someone build them for you, a wheelset like this one is easy to repair or rebuild in the future. 

Building these wheels was fun. I am anxious to ride these great looking wheels and see how they perform!
