ADAPTABLE GRAVEL ADVENTURES
Eight Bells GRAVEL & ADVENTURE
The Eight Bells Frame is Gravel to the MAX. This Gravel bike has been calibrated to run drop bars with larger tyres. We have taken everything that we have learnt from mountain and adventure bikes and adjusted the geometry for drop bars. Wider tyres mean more grip and more comfort on those long fire roads, this bike will take you places and back again.
The Eight Bells is the ideal bike for GRINDURO Events and COMMUTEERING. Commuting the long way home instead of going to the gym. This is your Bike has 65mm tyre clearance and will run up to 29x2.1” or 700x50c tyres. Wider tyres mean more grip and more comfort on those long fire roads, this bike will take you places and back again.
The Eight Bells has been designed a drop bar geometry fitting up to 50mm tyres. It is at home on forest roads with a sprinkling of gravel and dirt ruts. It is part commuter part adventure. You can ride this bike fixed or single speed. Great for shouldering up cyclo-cross climbs or built into a an Alfine or Rohloff hub to load up with touring luggage. The Eight Bells can run 415mm A-C Lauf GRIT Gen3 suspension forks...
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.
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.
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.
