Paul track build

Webmaster

For singlespeed wheels I like hubs from Paul Component Engineering and Phil Wood. I can suggest which are best for you and offer competitive pricing — please email.

This wheelset uses Paul Component track hubs laced to Stan’s Alpha 400 tubeless rims with Sapim Laser spokes and alloy nipples. Total weight is 1545g. Additionally this wheelset is getting tamper-proof torx bolts for a little extra lockup security. The bolts are a Paul upgrade option.

Easy rim, hard rim

This wheelset was an interesting study in the difference a rim makes. My runout target with machined rims is 0.25mm (with the expectation they’ll settle in to 0.33mm over the long haul). This wasn’t achievable on the rear rim, which finished at 0.26mm. I spent quite a lot of time getting it this good and the rim made it clear I could go no further. After improving the most extreme misalignment the rim would fold some other way for no net improvement. The distortion didn’t seem related to the weld area nor expressed in locations 180 degrees apart. Even so by industry quality thresholds of 0.50mm runout and ±20% tension variation, this is still a very good wheel. The penalty associated with less-than-perfect rims is mostly wheelbuilding benchtime. Indeed the front wheel was completed in half the time with better alignment and lower tension variance.
