90mm雪地圈展示

Nextie's Wild Dragon 90mm fat rim is officially upgraded to Mark II. We are proud to release it.

We kept the main structure design of aero shape and tri-angle cross-section, but updated two parts to improve the performance.

1) As drawings shown as below, the new rim hook was changed a bit more straight.

The advantage is to fit tire edge more tightly, also it would be better to prevent the tire from air leaking when it's used for running tubeless.

2) The other update is the rim bed depth. Comparing with Mark I's 19.5mm, Mark II's rim bed depth was updated a bit shallower, 16.5mm.

After our re-calculation, so deep the rim bed is not quite necessary. We found 16.5mm is a highly appropriate depth to work for mounting any tires to mount.By this change, not only did the rim weight decrease, but also the tri-angle structure got more stable, lateral stiffness increased.
