Blog: Stan’s Alpha 400 Rims

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.

Hope is a strategy

Webmaster

Hope hubs don’t have the tightest geometry or the lowest weight, but they’re solid kit for the money. I don’t sell them but they’re easy to find and I don’t mind building yours. Here are a couple of Hope wheelsets built this month — you might see them on the road in different parts of Alberta.

Variations on a theme

Webmaster

Stan’s Alpha 400 rims push the envelope of weight without concessions in strength — we can go lighter but not without hurting durability. Being deliberate about spoke count and spoke model, the same rims can be tuned for each rider. The first set is built with Sapim Race spokes, 24 front and 28 rear, which makes for a sturdy build.

The second set is built with Sapim D-Light spokes on the front and rear drive side with Sapim Laser rounding out the rear. This set is 20 spokes front and 24 spokes rear, which, as the scales show, makes for a 1453 gram alloy wheelset. Less stiff but a hoot at the same time.

White Industries T11 hubs mated to Stan’s Alpha 400 rims is a combination I’ve built (and ridden) in more than one incarnation. This set is put together with Sapim Laser spokes in the front and rear non-drive side, Sapim Race rounding out the rear. That puts total weight a hair over 1500 grams while remaining stiff enough for the rider. These wheels are setup tubeless with Stan’s tape and valves supporting Schwalbe Pro One tires in 700×28. A perfect combination top to bottom.

Wheels for Ryan

Webmaster

To cope with wet coastal winters I’m building a spirited road bike that takes fenders. These are the wheels I built for myself: White Industries T11 hubs laced to Stan’s Alpha 400 rims; Sapim D-Light spokes on the front and a blend of Sapim Race and Sapim Laser on the rear. 1518 grams total.

These wheels will run tubeless with Schwalbe One tires along with the full stack of Stan’s tape, valves and sealant. The cassette is Dura-Ace 9000 and the skewers are Dura-Ace 7900.
