Rennen Rollenlager - Single Speed Chain Tensioner

$49.99

We always love it when we can offer you a quality USA made part, especially when it is at a competitive price. The quality of workmanship displayed by all of the Rennen products we've come across so far is top-notch. The cogs take the best attributes of a Surly Cog but none of the weight. The Rollenlager is the best designed chain tensioner we've used, and the spacer kit has an ingenious new design allowing for perfect chainline without leaving you deciding between 1.8, 2.0, and 2.1mm spacers.

The Rennen Rollenlager is a single-speed conversion kit for vertical and horizontal dropout frames.

By strengthening the weakest link (the replaceable drop-out), Rennen has achieved a complete system of chain tension and drop-out protection.

Features:
- Machined ¼" thick 6061-T6 aluminum principal construction.
- Stainless steel hardware used throughout.
- Molded 80-durometer urethane roller houses two sealed cartridge bearings.
- Included with each Rollenlager is a stepped spacer insert that allows the use of both Q/R and bolt-on type hubs.
- Wide roller groove allows range of chain-line options, including BMX chains.
- 12mm/ 14mm axle compatibility standard.

Gross weight: 112 grams.
