The Superspeed takes advantage of carbon's flexibility to absorb riding forces to improve comfort and grip while maintaining the stiff pedalling characteristics of a hardtail. The most obvious example on the frame is where the seat stays bypass the seat post to join directly to the top tube. Silverback calls this Monoburst technology and they say it sends bump forces into the top tube instead of up the seat post to the rider. The design further enables the seat post to flex better which also improves comfort and traction for the rider.


The Superspeed is a single chainring specific frame which has helped Silverback to design the bike with short 422 mm chainstays. The frame is fitted with a minimalist chain guide (that can be adjusted for different chainring sizes) to make extra sure that no race losing mishaps occur. Silverback also made provision for an internally routed dropper seat post, which you can see Luke has decided to take advantage of.




Luke has selected some top of the range racing parts from SRAM's catalogue with a full XX1 drivetrain and a RockShox SID World Cup fork with Charger damper. The brake set is the carbon levered Level Ultimate which neatly integrates with the shifter and dropper levers.




The cockpit features a 740 mm carbon Truvativ Descendant flat bar with silicone grips. The stem is a lightweight Zipp Service Course SL, a brand more commonly seen on the road. The Fizik Tundra saddle with carbon rails is bolted to a Specialized Command XCP dropper seat post providing 35 mm of travel.



Luke uses Maxxis Aspen 2.25 tyres wrapped around a custom South Industries XC29 rims laced to American Classic boost hubs.

The complete build weighs in at 9.2 kilograms.
