All Season

Framesets from £1950. A deposit of £975 is required with balance on completion. 

The All Season is our bike with a true can do attitude. It’s a bicycle for adventure and adrenaline that goes beyond the road. Whether you are planning to cross a continent, do a gruelling audax or heading out on a bike packing escapade, the All Season is the bike for you. It’ll even be by your side on the daily commute. It comes fully equipped with everything you need in a modern adventure road bike; flat mount disc brakes, dynamo routing, 12mm bolt thru fork and much more. This is a frame- set designed for versatility, allowing you to tailor your wheel and tyre choice to suit your distance, tempo or terrain. Meaning this frameset builds as well into a fast road machine as an endurance mile muncher.

The steel is a custom blend of tubing, specifically selected from the best of what Reynolds, Columbus and Dedacciai has to offer, to create an optimal balance of flex and rigidity. To build you a bike which is stiff enough to attack another 20% climb out of the saddle, yet comfortable enough to deliver you to the end of a 400km in the best possible condition – considering the circumstances.

The frame is built to take disc brakes and has a proprietary boss-system allowing it to seamlessly accept either electronic or mechanical and 2 or 1X groupsets without the need for modification.

The All-Season also has mudguard mounts and internal routing for brake cables and a dynamo. Frames come in stock-sizes of 47cm to 61cm to fit riders from under 5” to well over 6”. The smallest frames sizes are paired with 650c or 26” wheels to keep handling at its best but still allow for tyre widths of up to 40c. The larger frame sizes allow for tyre clearance of 35c with 700c wheels, and 40c with the smaller 650B wheel choice (fatter tyres for fatter journeys).

We offer any of our bikes with either T47 or BSA 68mm BB shells.

BSA is the traditional BB system used on bikes for decades, and works very well. There are many options for BB’s and cranks at all price points and parts are easily sourced. If you were riding around the world you would want a BSA BB shell for ease of sourcing parts.

T47 is the frame building communities answer to BB30/PF30 BB systems. BB30 was originally designed by Cannondale, and has bearings that press (not thread as per BSA) into the frame. They are oversized and are designed to work with cranks utilising a 30mm axle, larger than the 24mm axle on Shimano cranks for example. This is advantageous as stiffness in the BB area is ‘free’ stiffness, it doesn't create any adverse ride quality issues that increases stiffness in other areas of the frame can. It also makes internal routing of Di2, dynamo wires etc far easier. However, due to the thin wall thicknesses on bicycle tubing, both BB30 and PF30 have been beset with issues with creaking, bearing surface damage and repeated development of play. T47 is the best of both worlds. A threaded bearing cup to remove any creaking issues, with the oversized bearings to allow the use of high end 30mm axle cranks. Any cranks designed for PF30 or BB30 will work, and BB’s are supplied by Chris King and white industries, who have both said they will not discontinue them as a product, so you won’t be stuck with an obsolete BB standard in 10 years. If you want the ability to run the best cranks, want your BB to be as stiff as possible,or plan to run wiring internally, this is the standard for you.
