Using beefy spokes

Webmaster

The typical spoke decision is between straight gauge and some double-butted model. For conditions outside the bell curve, there are two specialty models.

Sapim Force is a triple-butted spoke with a 2.18/1.8/2.0mm profile. They are similar to Sapim Race with a little more meat on the vulnerable elbow section. There is a cost penalty but weight and stiffness are about the same. Fatigue life is better — if you’ve been burned by broken elbows, Force might be the ticket. I often use Force on touring and bikepacking wheels to work with 32 spoke wheels when 36 might be more conventional (opening up more choices for hubs and rims).

Sapim Strong is a single-butted spoke with a 2.3/2.0mm profile. These are the biggest bicycle spokes I sell and I stop at this gauge because it’s the biggest spoke that works with regular nipples. Strong shares the massive stiffness of Sapim Leader but has a serious amount of extra material on the elbow. People use Strong for e-bikes, cargo bikes and the heaviest touring applications. For regular day-to-day use they’re overkill though I’ve used them for riders >400 pounds.

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.

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 7.7mm 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. Get MS washers and three other types of nipple washer here.

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.
