Bike Check: Luke Moir's Silverback Superspeed

Up-and-coming Cape Town mountain bike racer Luke Moir (15-years-old) will be riding Silverback's 29er carbon performance hardtail the Superspeed this season. Take a closer look at Luke's race bike below.

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.

If those wheels ever go missing, I might have nicked them.

TheJ, Jan 26 2018 07:45

Thats a R20k wheelset. Rims R7k each, hubset R2500. Can't tell what spokes are used.

Nice build with some super interesting bits! Check out the spoke nipple detailing on those South Wheels-Sweeet!

Being a sponsored rider he (or his parents/sponsers) would not have paid full retail for it. Sponsored riders don't pay what you and I pays for parts. 

He rode for SRAM, and it looks like Cape Cycles Systems are still in the mix, so they probably would have sponsored (or given discount on) the hubs.

Luke is already way too fast. He doesn't need this.

Need is one thing; want and deserve is a completely different. The way he rides, he deserves that bike!

Noob question but what difference does a 35mm dropper make? Is that enough to give you the same advantage of maneuverability as the bigger droppers?

Doubt this will be doing anything remotely 'trail or enduro', so 35mm is plenty to get through gnarly/sketchy sections on an XC course. For a talented rider, 35 is probably all that's needed

i had a blue one of these when i was 15....loved it.

Very bling bike! Good luck for the season, on that bike you should be winning everything! Haha

35mm (specs wrong??) travel dropper post :eek: ??? For that little travel I would have saved the weight. :whistling:

Just enough so the saddle doesn't slap your gonads when barreling through a rock garden.

cough ... triple triangle .. cough

Jisso. Now that’s a mooi fietsie!
Perhaps I should give up this med student life and dedicate my time to training...

Saw Luke at EzelEnduro last year. Cheeky little bakgat knows how to roll those wheels!

Good luck, Luke! Stay away from the needles and I’m on your side all the way.

That happened to me years ago as a junior in a XC race. Literally had to withdraw from the race.

Need a Gin and Tonic for your cough there ?
