We Bring You the TiPin LS

The most radical Fatbike in the world

•   Progressively radical geometry
•   Titanium ride quality
•   Low maintenance drivetrain
•   Versatile wheel compatibility
•   UK rider developed


So whats all the fuss about?

Smokestone bikes bring you the all new Ti Pin LS. As the name suggests this frame is made from the wondrous material that is grade 9 3Al/2.5V titanium. The “Pin” part of the name comes from the 12 speed Pinion Gearbox that is strapped to its under belly, as for the LS, let's just say the geometry is bang up to date, so Long and Slack. Adding these into the mix with a well damped 140mm fork makes this baby something to behold through aesthetics as well as performance.

The Ti Pin LS is unique and pushes the fat boundaries even further, not only will this bike take you anywhere but now you can climb and descend the gnarliest trails in the knowledge that you are in safe hands.


The Gearbox

The Pinion core technology is built around spur gearing. This provides high-precision shifting. Permanently reliable, wear-free, low maintenance. Pinion transmission delivers long-lasting performance and reliability perfectly suited to go with a fatbike. Centrally integrated in the bicycle frame and protected by an enclosed housing, the gearbox is the epitome of innovative bicycle drive technology.

Our first test bike was fitted with the P1.18 version. After many hours of testing we have decided to spec the more affordable and lighter C-Line.

The C1.12, which is 12 speed and has a lighter magnesium casing and still has all the benefits of its more expensive bigger brother.

Full technical information on the gearbox including gear ratios can be found here

Useful Info

We are a great believer in keeping things simple, try and use standards that exist and components that you can get in most bike shops. 

Rear dropouts

The dropouts are adjustable to tension the chain. The axle is 12mm bolt through

Headset type

Integrated headset size IS42 top and IS52 lower. This type of headset does not require cups to be pressed into the frame as the bearings sit directly into the frame.

Pinion supply cranks and a spider specific for fatbikes. 


Seat post

The seat post size is 31.6mm and the frame can take an internal dropper post, the cable routing exits the frame just above the gearbox then has external guides up the down tube, making it super-easy to maintain and fit.
