RocknRollout Dropouts

The RocknRollout Dropout is at the heart of the OLSEN frame design. We have focused our design around the rear derailleur dropout, but taken it further. Most bicycle frames have replaceable dropouts, but they do not allow for anything other than a derailleur. This idea came from the fact that UK riders often have a winter bike, which is often single-speed.
The RocknRollout Dropouts turn 1 Bike into 2 Bikes giving the rider more versatility. Summer bike with derailleur; winter bike as single-speed or internal gear hub.

Riding Bikes through Mud, Sweat & Tears.

Based in Sussex near the South Downs Way - we are used to different types of mud. In fact, Sussex has more than 30 dialect words for mud. The South Downs Way is a mixture of flint, clay and chalk. It's infamous for poor draining soils that set like concrete in summer and porridge in winter.

Choosing Gates Carbondrive ensures your ride or event isn't hampered by mechanicals inflicted by mud. And it means that the clean-up afterwards is fast and efficient.

Clever Fox...

Singlespeeding is cheap, fun and allows you to ride more, spending less cash. I just do not understand why other people are so reluctant to try. Our great grandparents would have had little or no choice. We can all learn to live with less tech and we all need to convincing to try something new or old…

Here are some gear ratios so that you are never in the "wrong" gear:

• 29er start with 32:19T
• 27.5 start with 32:18T
• 26aint dead start with 32:17T
• Belt start with 39:24T
