Welcome to OLSEN Bikes
If you are after low maintenance drivetrain, forget the derailleur, you will be looking at Single Speed or Internal Hub gears, like Shimano Alfine, Rohloff Speedhub and Kindernay XIV. There are also other alternatives like the Pinion Gearbox. At OLSEN HQ we have developed our bikes to fit chains and derailleurs, but to work even BETTER with Gates Carbondrive.
Experience from the REAL World:
Chains have links that rust, trap mud, water, and grit, and must be oiled. Remember that a derailleur chain drive system has more than 98.6% losses with its crude forever changing chainline. Gates Carbon Drive runs clean and sheds water, mud, and grit. Is there a winner to the belt vs chain test?? That depends on whether you are looking at results from the Lab or from the Real World. In real-world conditions, belts are the clean and simple winner.
PINION GEARBOX BIKES
PINION GEARBOX BIKES
OLSEN have extended their PINION Gearbox bike range – this will take you further with less maintenance.
The MOKIHINUI Gearbox was the first, now we are following with the KARAPOTI Gearbox version. Based on the same geometry as their Bottom Bracket Brothers, these gearbox frames are more than a match for the miles.
Dropouts: RocknRollout dropouts allows the frame to do 3 things:
- the rear hanger to be replaced if a derailleur is damaged.
- splits the frame for belt drive.
- adjusts the wheelbase for belt/chain tensioning.
OLSEN RocknRollout dropouts can be replaced and 142 can be replaced for 135. 142 is a stable internal hub gear format for Kindernay and Rohloff. 135 has a large second hand market with Rohloff and Alfine11.
ROHLOFF SPEEDHUB BIKES
Rear Wheel 142mm O.L.D.:
142mm has been adopted by Gravel bikes and there are loads of single-speed hubs that are 135mm an 142mm... 135 & 142mm are extremely popular with internal hub gears. Rohloff, Kindernay both offer 142mm. Shimano Alfine 11 comes in 135 and the Secondhand Rohloff market is full of 135mm hubs.
SHIMANO ALFINE 11 SPEED HUB BIKES
Head Tube ZS44 EC44:
The SHIS standard of 44mm top and 44mm bottom is genius. It might have been luck, but the bike industry got it right this time.. Zero Stack 44 top cup and External Cup 44 bottom cup with a 52mm bottom bearing.
