RATCHET DRIVE HUBS | HARDENED ALLOYS | SAPIM SPOKES

Technology

Wheels, like no other

At SILT MTB, we challengetest and obsess over the smallest of details to explore what's possible with product development, and to make sure we bring you the best product possible. The below provides a snapshot of the level we go too...  

Hub Technology

SILT Ratchet Drive System - Exclusive to SILT, we use a single disc Ratchet Drive System, with leaf spring actuation. Included with all of our performance wheels, this is a responsive, high torque system that offers almost instant drive when the power goes down. 

The biggest advantage of a Ratchet Drive System is that ratchet faces engage simultaneously, every time, which helps increase durability.

Rim Technology (Carbon and Alloy)

Chemically Enhanced Resins - As Resin affects the strength, weight, and thermal ability of carbon rims, it’s important to get the right mix; for the purpose.

High Tier Carbon Fibre with Spoke Hole Reinforcement - At SILT, we only use Japanese Toray, high filament (12k / 18k), carbon fibre for our carbon wheel range to make sure all carbon wheels with our logo; are super-light in weight, and incredibly strong. This includes extra reinforcement at spoke holes.

X-Ray QC check - Phase 1 QC check for carbon reinforcement at spoke holes

Hardened, Super lightweight Alloy - light enough to spin your way to the top, but strong enough to take impacts. SILT alloy rims go through extreme heat treatment processes to produce exceptionally strong, yet lightweight rims. As weight generally slows wheels down (especially when weight is far away from the hub, centre point), this means we can build you incredibly fast responding hoops, with low weights. 

Spokes and Nipples

Sapim spokes - Produced from high-tensile, fatigue-resistant 18/8 stainless steel, Sapim spokes produce some of the highest fatigue tested results out there. Used on most of our range, the Sapim D-light offer incredibly high strength and durability

Bearings and Grease 

Bearings and Grease - Bearings are an essential component for every wheel set, and we have spared no expense to get the right bearings & grease for the purpose. All of our wheels come with 6x sealed stainless steel bearings; 4x in the rear, and 2x in the front. The bearings are sealed with 1x contact and 1x non-contact seals and they come with Aqua grease (water tight bearings, and water repellent grease - still fast and will stand the test of time).
