New nipple washer

Webmaster

There’s a new nipple washer available from Sapim — the Sapim MS washer has a generic V-shape profile compatible with all nipples (compare to Polyax washers with a Polyax-shaped cup). It has a thick, flat bottom for superior weight distribution however needs a flat resting spot 7.75mm in diameter. Where applicable, these stainless washers will impart a lot of strength.

Not much information is searchable for Sapim MS washers so I’m posting the product sheet to give you information from the source. Note carefully: my measurements put the diameter at 7.7mm compared to the nominal 7.4mm listed in the datasheet.

More things weighed

Webmaster

Up in the utilities menu I have a little tool to compute spoke weight. Today I made a couple tweaks.

First I got a better scale in the shop, which helps because this tool is based on real world weights. At the same time I changed the sample weight from 300mm to 310mm spokes. The original idea was to depart from the norm of specifying weight based on short spokes. But since I sell spokes longer than 300mm, why not choose samples of the longest length? Job done.

Second I added all varieties of nipples sold here to the measurement tool. This update includes brass and aluminum nipples in all varieties. Still to come are spoke washers and nipple washers though they weigh next to nothing and are worth it when they’re needed.

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.
