Transform your bike into a pure single-speed machine! The Dartmoor SINGLESPEED KIT Micro Spline provides your drivetrain with a perfect chainline, maximum reliability, and a clean look for dirt, pumptrack, and trail riding.
Do you want to convert your bike with a modern Shimano Micro Spline freehub into a clean, reliable single-speed system without unnecessary derailleurs? The Dartmoor SINGLESPEED KIT Micro Spline conversion kit is the ideal solution for all riders who demand maximum drivetrain reliability and a clean bike look. Whether you're building an uncompromising rig for dirt jump, pumptrack, slopestyle, freeride, or looking for a low-maintenance setup for your trail bike, this kit ensures a dialed chainline and absolute confidence with every pedal stroke.
Switching from a standard multi-speed cassette to a single-speed setup on modern hubs with Shimano Micro Spline freehubs can often be tricky. The Dartmoor SINGLESPEED KIT Micro Spline elegantly solves this problem. Thanks to precision-machined spacers and cog design, you can set up a perfectly parallel chainline. The result is a drivetrain free of chain angle drag, eliminating unwanted skipping and giving you unwavering confidence when cranking hard on jump take-offs or through technical sections.
At the heart of the conversion kit is a 13-tooth cog (13T), delivering the ideal gear ratio for pumping on pumptrack lines and bursting out of dirt jump turns. The entire kit weighs a mere 79 grams, making it an exceptionally lightweight addition to your wheel's rotating mass. The black anodized finish (Black anod.) guarantees not only a sleek, clean aesthetic but also long-lasting resistance to dirt, grime, and harsh riding conditions.
To achieve the highest possible reliability, this kit was developed as a direct companion to the Dartmoor Singlespeed Tensioner. Together, they form an uncompromising setup for frames with vertical dropouts or full-suspension freeride and jib rigs. You get rock-solid chain tension, worry-free operation, and complete trust in every pedal stroke even on the hardest landings.

Yes, if you are converting to a single speed on a frame without sliding/horizontal dropouts (or on a full-suspension bike), you will need a tensioner to take up chain slack. The kit is specifically engineered to pair with the Dartmoor Singlespeed Tensioner.

A great shop with a thoroughly professional yet human approach. I have been ordering from them for a long time and there has never been any problem. Communication works perfectly and you know where you stand right from the start.
I now have my second Haro bike from Katmar Bike Center – this time an e-bike. Completely satisfied. Professional and helpful approach. I warmly recommend this shop.
Reliable. I bought a new chain, it turned out to be unsuitable, but exchanging it for another one was no problem.
