ROCK N ROLLOUT 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.

T47 X 92 BOTTOM BRACKET

There is a lot going on in this part of the bike frame. Tyre and chainring clearance, but also frame stiffness. T47 internal keeps the bottom bracket nice and wide, while resolving the issues with PF92.  A 92mm shell allows the chainstays to be wider, providing more tyre clearance.  92mm also means that the chainstays can be welded wider on the frame, making the bottom bracket area stiffer for belt drive use. 

HEADSETS ZS44 EC44

I chose the straight 44mm Headset "standard" for several reasons. They are straight and keep a simple look, while hiding their versatility. Zero Stack 44mm (ZS44) top or bottom cups and the External Cup 44mm (EC44) bottom cup. In SHIS codes 44/44 allows for both Tapered Carbon fork steerers using ZS44/EC44 and is backward compatible with straight steerers with either a crown reducer or a ZS44/ZS44 headset.

ROHLOFF COMPATIBLE

If you're planning a long-distance bike packing tour, one of the best upgrades you can make to your bike is to switch to a Rohloff geared hub. A Rohloff Speedhub offers a number of benefits over a traditional derailleur system.
Its durability, smooth shifting, and wide range of gears make it the perfect choice for touring on any terrain.
