Add Style to your Ride.

We want your bike to look as fast as you are. That's why we developed the PowerTap Front Hub. Its sleek design matches the exterior of the PowerTap G3 and PowerTap G3C hub. So now, while you're measuring power with your rear hub, you'll be riding in style with a matching front hub.

Spokes

Spokes if Sapim CX Ray 4.1 grams each bladed aero. Blade is 2.3 mm x 1 mm

Spokes if Sapim Laser 4.1 grams each Double butted 2.0-1.5-2.0

Spoke Tension Rear : 130-140 KGF (on a Park Tensiometer 13-14 for CX Ray and 18-19 for Laser).Note:

Wheels come with extra spokes and the exact length is indicated on the spoke package. We occasionally substiture when we are out of a particular length.

Spoke Prep

We use Loctite 242 on the non drive side spokes and on the front spokes during the building process (no lubricant). On the drive side rear spokes we use a lubricant to build (nothing special - just something slippery) and after the build put some Loctite 242 in to finish them off. The Loctite 242 will make the spokes harder to turn but will not sieze them.

Spoke Nipples

Alloy 14 gauge uses Park Black Spoke wrench

Skewers Not included with Powertap wheels

Tire Recommendations

With the wider rims, you can use pretty much any tire width you want - from 19 mm all the way up to over 30 mm. I like 25 mm wide tires simply because they hold more air and are more comfortable. 23 mm tires are probably the fastest and are the most aerodynamic. As you get bigger tires, the limiting factor is the frame. Typically the tires will first rub on either the brakes (on the top of the tire) or with the rear tire hitting the seat tube. Most road bikes will fit up to 25 mm tires, a few bigger ones, and many won't even fit a 25 mm tire.

Tire Pressure Recommendations

With the wider rims you can generally run at least 10% less pressure than with a narrower rim because the system holds more air. Less pressure is better because you have a bigger tire patch and will roll over the bumps in the road instead of bounce over them (it's that sidewall flex that gives you better rolling resistance). Most people run too much pressure in their tires because they believe they are faster (and they feel faster at first). If the roads were perfectly flat that would be the case but they all have lots of bumps so lower pressures make sense. Generally speaking a 160 pound rider should be around 80-90 psi in the back tire and 75-85 in the front. If you have been running higher pressure you will immediately notice how much more comfortable the ride is and how much better the bike handles around corners.

Documentation

When you receive your wheel it will include a package with the extra spokes and some documents. The documents will list the builder and on alloy wheels a serial number (which is under the rim strip near the valve hole on both wheels). Also included is a spec sheet showing the type and length of spokes used and the spokes tensions for your wheels). We keep a record of your info here so you can contact us with either your invoice number (preferred), serial number (also OK), or your name and we can pull up your records.

Service

Powertap recommends that all Powertap service be done by Powertap. They have far more expertise in the electronics than we do and have an excellent reputation for quality service. They have a two year world wide warranty.
