Paul Components Chain Keeper - Black

The Chain Keeper is a guide to keep your chain right where it belongs.

Mounted in place of a front derailleur, the Chain Keeper works with single chain ring drivetrains using a narrow chain. The chain block surrounds the chain as it meets the chainring and prevents it from skipping off.


The Chain Keeper clamps on to the seat tube of the frame. The portion of seat tube where the clamp mounts must have a circular profile and a diameter of 28.6, 31.8, or 35.0mm, (+/-0.5mm).


Designed with adjustability in mind, the Chain Keeper can accommodate a range of chainline measurements and chainring sizes. However please note that Chain Keeper may not work with all frames.


Note: This product is not designed for downhill, freeride, or big hit use.

Paul Components Chain Keeper BB - Black

The Chain Keeper BB is designed for use with external (outboard) bottom brackets. This allows the Chain Keeper BB to be used with full suspension frames, carbon fibre frames and frames with non-standard tubing.


This chain keeper is attached by a plate that replaces the 2.5mm spacer found on many external bottom brackets.


The Chain Keeper BB can accommodate a range of chainline measurements and chainrings from 28 to 39 teeth in size.

Weighing less than the lightest road derailleurs on the market, a Chain Keeper can help you cut weight from your bike. Plus, you lose the weight of the shifter, cable and housing, which can be substantial.


The Chain Keeper BB is compatible with frames with 68mm or 73mm shells, and will work with Hollowtech II, MegaExo, Giga-X-Pipe and other outboard bottom brackets.

Paul Components Melvin Chain Tensioner - Black

The Melvin bolts to the frame where the rear derailleur would normally go and allows the use of a single speed rear wheel on bikes with vertical dropouts.


Vertical dropouts hold the rear axle at a fixed distance from the cranks. Nine times out of ten this doesn't put the rear wheel at the right spot for a single speed drivetrain and the result is a chain that is too loose or too tight. The Melvin takes care of the chain tension and lets you run a single speed wheel on almost any frame with a derailleur hanger.


The Melvin uses two pulleys, just like a rear derailleur, which gives it 20 teeth of chain wrap. This means that the Melvin will work with multiple front chain rings while maintaining proper chain tension. Of course this is no longer a true single speed, but can come in handy when two or three gears is all you need. Twenty teeth of chain wrap means that chain rings with a maximum difference of twenty teeth can be used up front.


The mounting pivot has spacers that can be arranged to adjust the chainline. Chainline spacers allow it to work with most hubs. In addition to the pivot spacers, the pulleys have side to side float to quiet slight variances in chainline.


Pulleys are made of extruded and machined aluminium and have sealed bearings for durability. They are 2.25mm thick at the tooth which fits inside most narrow multi-speed chains, and the pulley cage is wide enough to allow 1/8" single speed chains as well.
