Trek's Belt-Driven Single Speed

Mix a carbon-frame road bike driven by a carbon-composite belt and you end up with a super quiet, super light single-speed bike. You also get Trek’s unique and drool-worthy District Carbon.

Weighing 20 pounds, and costing $3,360, the District Carbon is one of only a few belt-driven bikes in Trek’s fleet. Not to mention one of the coolest-looking single-speeds on the market.

While 20 pounds is heavier than I expected from a carbon single-speed, according to Trek, the bike wasn’t produced with its lightest components for a reason: to let the consumer upgrade if he or she wants. That way the price — still quite high at $3,360 — doesn’t go through the proverbial ceiling, Trek said.

Trek hit the belt-drive market relatively early compared to many other major manufacturers. Its high-end carbon bike — built with Trek’s “Optimum Compaction” low void carbon — is based off of the company’s high-end road bike, the Madone.

Trek’s OCLV carbon reduces gaps between carbon layers

The carbon fiber is heat- and pressure-treated in a way to increase strength and decrease microscopic gaps between carbon layers, the company says.

The Trek District Carbon, which comes in 50, 54, 56, 58 and 60cm frame sizes, is currently available. With primarily Bontreger components, a nearly all-black stealthy look, and an almost maintenance-free belt drive, the bike is bound to make eyes blur.

looks pretty cool, but…..$3,360 for a 20lb carbon single speed?!?!?

This is ridiculous. A “stock” 18 speed Trek 1000 isn’t much heavier, but a LOT LESS money. For $3,300, I’d expect a sub-17 pound bike.

I agree with both of you. As I mentioned in the news story above, I expected lighter too. The Trek rep that I talked to said an employee built a District Carbon sub 12 pounds —

But that’s still a lot of $$$.

My $700 aluminum District weighs 20.5lbs. Something doesn’t add up here.

I have one on order can’t wait! 20lbs is fine and is a great platform for making it a much lighter bike, the wheels are average and weight a bit, the stem isn’t light and the crank isn’t either…I figure I’ll get mine down to between 12-14 pounds once finished – it’s a great winter project.

Parlee cycles just made a one-off carbon single speed that can except a belt drive but it’s $$$$ and only made as a custom.
