Feature Bike - Top-Fuel Custom Build

The Top-Fuel is a quick, short-travel 29er trail bike that’s perfect for riders who like to stay pinned both up and down the trail. It’s lighter and snappier than a trail bike, but it’s a lot more forgiving on rowdy descents than a true cross-country bike. It’s the best of both worlds and a hell of a lot of fun in the dirt.

Rip down and rocket up any trail with the Top-Fuel ’s capable and efficient suspension. 120 mm of travel front and rear gives you enough squish to take bigger hits while a low leverage rate and high anti-squat ensure that this bike jumps forward with every pedal stroke.

The Top-Fuel ‘s efficient pedalling comes from a forward pivot on the seat tube that provides optimal, near-constant anti-squat through the entire travel. So, regardless of where you are in the travel, the bike accelerates when you push on the pedals.


A steeper seat tube means that you’re pushing down on the pedals while also keeping the front wheel weighted.

Removable Knock Block 2.0 keeps cables from getting yanked out in a crash and protects the top tube, but now it provides 72 degrees of turning radius.

Mino Link lets you fine-tune your frame geometry on the go. Stay in low for a slack 66-degree head tube angle. Flip it for a quicker 66.5-degree head tube angle and a 7-mm higher bottom bracket for more ground clearance.

This Particular Top-Fuel was a custom build for a customer who was originally looking for a top-spec prebuild. With shortages in supply and urges to make something fun and unique, the idea was broached that we could build him something a little more than your average rebuild! With that being said we got to work finding some of the best components for all of his trail needs. 


For the frame, that was easy, we stayed with the Top-Fuel platform because of its efficiency on the uphill all the while being able to manage itself and roll with the punches going down. For suspension, we decided to make a match in haven with Fox Factory 34 Step-Cast forks to match that beautiful Kashima coated rear shock. This would give the customer ample adjustment and enable them to tune in to the ride.

For Group-set we spared no expense with the Shimano XTR 12 speed build, matched with some quite controversial SRAM XX1 carbon cranks. This benefited the customer as it added the much-loved option of the SRAM AXS QUARQ Power meter. Wheels were an easy choice for us to recommend with stunning performance price and aftercare the Bontrager Line Pro wheels were just a no brainer. 

They are strong, have amazing value for money and are lightweight so would feel right at home underneath the Top-Fuel. Paired with a set of fast-rolling tubeless XR3 tyres it could just be an XC match made in heaven. 

Finally finishing kit, when you have gone this far already, we didn’t think there was a better way to go other than the Bontrager RSL integrated handlebar and stem, sleek, lightweight and super comfortable for those rugged descents. It was a real winner in our eyes.
