A Drop-Bar 29r for ultimate float and traction.
— What is it?

Confident and Surefooted.

Quirk Cycles latest model is the antidote to dubious under-tyred gravel bikes. Built around the 29er platform, the SUPRACHUB can take up to 2.3” of rubber for ultimate float and traction. This bike is confidence inspiring, always asking for ever more technical trails and never losing its grip. Its skinny stays joined to 3D-printed cluster + dropouts increase rear-end grip through compliance, while integrated cabling protects delicate hoses and shows off the lustrous Rose-Gold-Candy clear. It’s the ultimate in high-end steel Gravel technology.

We wanted a gravel bike that could handle bigger tyres and gnarlier trails inspiring confidence.
— Why we made it?

Not sold on a MTB but want to tackle difficult terrain?

The SUPRACHUB takes the 29r platform and builds it into the ultimate drop-bar gravel bike. Large tyres and good clearances offer great float and traction; slack head angles and long wheelbases keep you surefooted over rough terrain; skinny seat stays flex keeping the rear wheel stuck to the floor while providing cush-for-your-tush.

Anyone looking for the best in off-road capability in a drop-bar format.

To fit those chunky MTB tyres, we designed this model around MTB or gravel wide cranksets.

In-house designed 3D stainless dropouts improves compliance, increases strength and reduces weight.

ROCKSHOX RUDY FORK

Compatible with the Rockshox Rudy Gravel fork, and 30/40mm front travel for extra control in the dirt.

54ID OVERSIZED HEADTUBE

Unique to the SUPERCHUB, our in-house designed 54ID headtube improves strength and reduces weight with recessed 1.5” upper and lower bearings.

29R PLATFORM

Clearance for 29x2.3” tyres increases float and traction in all conditions.

 

Ultimate Traction Geometry

We designed our Ultimate Traction geometry to take the best features of modern MTB design and tune it to meet the demands of drop-bar gravel riding. The head angle is slackened for better rolling and stability on rough terrain, while the high BB compensates for the long wheelbase for spirited handling. The longer rear end makes the bike climb like a goat without sacrificing cornering ability.
