Sun-Ringle’s added two new rim options, one for fat tires and one for fat bikes.
On their complete wheels, they’ve licensed Stan’s BST (Bead Seat Technology). So you’ll find the same interior bead hook shaping on their Black Flag and Charger wheels as you will on Stan’s NoTubes rims. But, that license doesn’t carry over to standalone rims. So, Sun-Ringle developed their own tubeless ready extrusion and pinned and sleeved it into the Helix…
It’s available in 25mm (19mm internal) and 27mm (21mm internal) widths.
They have a lower sidewall than their Inferno rims and have a bead lock bump to keep the tire seated. They’re available in all three wheel sizes (26″, 27.5″ and 29″) for aftermarket and OE customers. Weights are 450g to 500g for the TR27 (27mm wide). Coming in June.
The Mulefut, named after a type of pig, is an 80mm wide, single-walled fat bike rim. The MF80SL shown here has the drilled out center to save weight, putting it at a claimed 795-800g weight. A non-perforated version can be done for OE customers.
It has a bead hump for tubeless set ups. Dual 32-hole rows of spoke holes allow centered or offset builds.
It also uses a pinned and sleeved construction. Could be available as early as end of May.
