super fast gravel



This is our Lightest Gravel Bike, made from Columbus & Dedaccia Titanium tubing.  Based on the Eight Bells, but we have engineered it around the derailleur drivetrain.  This bike is ideal bike for GRINDURO or UNBOUND Gravel Events. This frame is based on the 8-Bells with 65mm tyre clearance and will run up to 29x2.1” or 700x50c tyres.  Like all Olsen Frames the World's End is named after pubs in Sussex, however there might be a Worlds End Public House near you?

The Worlds End is designed around Shimano GRX or SRAMs XPLR ASX derailleur groupsets. How do we make a Gravel Bike lighter? We make our frames in the UK, so we can control the process, combining 3D titanium parts and double-butted European Titanium tubes. The Worlds End can run 415mm A-C Lauf GRIT Gen3 suspension forks...

t-type compatible

Choose your tribe. Ford or GM... SRAM, Shimano or Campagnolo.

We work with you to design the frame for the drivetrain you prefer. SRAMs T-Type has a lot of promising features, however you can run Shimano or Campagnolo with the UDH until you are convinced.

UDH dropouts

If you want to run Gates Carbondrive and want something versatile, then go for the 8-Bells. If you only want something tuned for derailleur drivetrain, then you want the Worlds End. Work with us to design the bike for your needs.

We offer 3D printing and can design features to accommodate your needs.

t47 x 86 bottom bracket

T47 internal keeps the bottom bracket nice and wide, while resolving the issues with PF86.  A 86mm shell allows the chainstays to be wider, providing more tyre clearance.  86mm also means that the chainstays can be welded wider on the frame, making the bottom bracket area stiffer for extra power.


We can offer either straight 44mm Headset or Tapered 42/52 Headsets.

Both Headsets are perfect for Tapered Carbon Steerers. 44mm headsets can be used for truss forks with 11/8" straight steerers.

made in the uk

Olsen Bikes are now making Titanium Frames in the UK. We wanted to develop lighter frames and offer custom geometries. We have been working with 3D printed titanium to get faster production results. We prefer to use Columbus Hyperion Titanium, however we canalso use plain guage or Dedaccia or Reynolds. We use grade 5 6AL4V and grade 9 3AL2.5V double butted Titanium to reduce the frame weight.

In 2024 Olsen Bikes have put all of this together to launch our Titanium frames which are Faster, Lighter and offer more custom geometries. We can design a geometry based on experience from our standard bike range. Olsen Bikes have simplified our prices across the range and can offer Pinion, Shimano or SRAM bikes with Hope Finishing Kit.
