Cycle Monkey are the USA distributor for high-end touring components like Rohloff hubs, Gates Carbon Drive and SP-Dynamo hubs, as well as touring bikes by Tout Terrain and Shand. Their bike build blog (The Monkey Lab) features some nice custom builds using some of my favourite touring parts.
For this Surly Troll build, or “Trohloff” due to the fact that it employs the 14 speed Rohloff rear hub – it wasn’t just a case of ordering all the bits and throwing it together. This customer wanted to be able to split the frame in two so they could reduce the cost of flying, and also wanted to pair a Gates Carbon drivetrain to their bike to reduce any maintenance.
So The Monkey Lab sliced open the frame, added some S&S couplers, added a frame splitter for the belt, and powdercoated it all white again. The results are great!
The Surly Troll is designed with Rohloff use in mind with its horizontal dropouts and torque arm slot. The key benefit of a Rohloff hub is that your gears are all enclosed in a sealed unit, impervious to mud, grit and grime. They’re almost completely maintenance free when compared to a derailleur drivetrain.
With a frame splitter installed into the seatstay, this Trohloff can use a Gates Carbon belt. Given that I managed to get 30,000km out of a single belt while I was travelling around the world, this drivetrain is the real-deal for touring. The only maintenance I ever performed was a quick belt clean with some water and a toothbrush every month or so.
This bike uses another of my favourite bits of off-road touring gear, the Cane Creek Thudbuster seatpost. On roads with lots of holes and corrugations, this seatpost dampens most of the vibrations and big hits coming up through the bike to keep you as comfortable as possible.
This Trohloff makes use of a Tubus Logo steel rear rack (another of my favourites), Schwalbe Marathon Mondial tyres (yet another of my favourites – what other tyre can survive 25,000km of use?) and Planet Bike Cascadia fenders.
A dynamo system has been set up with a switch on the handlebars to power either USB devices or the dynamo light set. The Busch und Muller Luxos U is a fantastic integrated system that takes care of everything. Given how many devices people carry these days, it’s always nice to be able to top up your electronics while going about your day.
SP Dynamo PD-8 hubs are proving quite reliable over time, and given they offer a significant cost-advantage over a Schmidt – they’re becoming more and more popular.
The Surly Troll is a pretty ideal bike for off-road, world-conquering adventures. The 26″ wheels will fit large volume 2.7″ wide tyres. The frame can be run with a Rohloff or derailleur drivetrain depending on your budget. It will run v-brakes, cantilevers or disc brakes. There’s a trailer mount on the dropout and braze-ons all over the bike for porteur racks, Anything cages, OS bidons, fenders and racks. And with the couplers and belt drivetrain – it’s even more sweet.
Thanks to Cycle Monkey for providing the images and putting together such a tough bike!
