Jasper – DT Swiss 240s Single Speed hub, Stans Arch rim and 36 point ratchet ring
This singlespeed rear wheel will be heading down for the Kiwi Brevet in February.
It’s a DT Swiss 240s single speed hub. Normally these hubs have 18 engagement points but DT Swiss recently released an upgrade kit to double the engagement points to 36.
The new ratchet rings are also 9 grams lighter than the 18 point version because of some amazing machining work.
The rim is a Stan’s ZTR arch – their 420 gram “all mountain” rim which is really well suited to applications like a single speed where lateral stiffness and durability are needed.
I used DT Swiss Revolution spokes to reduce weight – since the rim is so stiff we didn’t need to use stiffer spokes.
Total wheel weight was 820g before the 9g reduction from the ratchet rings.
Like all of the Stan’s wheels I build these are shipped with the yellow tape and two valves so they’re ready for use with inner tubes or with tubeless.
