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

Features:

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

- 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.

- 12mm/ 14mm axle compatibility standard.

Gross weight: 112 grams.

This is the single cog spacer that all the others wish they were.

The Rennen Design spacers allow you to adjust your chain line via threads on the spacers so you can get that elusive perfect chainline for trouble free, drag free running and no dropped chains.

The kit includes a half link joining link to help you acheive the perfect chain length.
