JSUMO SLT20 Aluminum Silicone Wheel Pair

JSumo's original large-format mini sumo wheel — machined aluminum hub, soft silicone tire, produced in small batches. The larger 33mm diameter gives a longer ground-contact patch than JSumo's 26mm JS2622 line, which matters for grip on soft, tacky silicone (contact area — not just clamping force — drives real-world traction).

Included: 2× wheels, 2× M4 setscrews, 1× Allen key.

Aluminum vs steel hub: use aluminum where every gram counts toward your traction budget, steel (SLT20P) where hub rigidity or wear resistance under repeated stall matters more than a couple grams.
