Aspect2 Campagnolo. From: £5,950.00

Threaded Bottom Brackets

We choose a more traditional 68mm, BSA, threaded standard for our AdventureSport frames because we believe it gives greater durability and creak-free reliability over many miles. The threaded BB is easier to service using standard tools and you are more likely to find a replacement when adventuring far from home. A properly lubricated, threaded BB is also an ideal interface with a metal BB shell.

Hourglass Stays

We tried many shapes before settling on this one, the wall thickness tapers from top to base and the perfect ‘hourglass’ profile gives a sublime, smooth ride with the added spring of steel keeping things lively. We add a custom bend at the base to work with the disc-rotor and calliper.

Aperture2 Fork

Designed and tooled for by us and unique to MASON. This frame is fitted with our beautiful 'Aperture2' 365g, Ø12mm thru-axle/flat-mount, monocoque carbon fork.

Features: Mason F-Stop axle system including replaceable axle inserts, TrueTaper steerer, Internal Routing for Dynamo and brake-hose, Full mudguard clearance, space for 32mm tyres + 'guards [up to 35mm without 'guards, depending on rim/tyre spec] Custom layup UD carbon construction, discrete eyelets.

27.2 Seat Post

Our oversize seat tubes don't house oversize seat posts. The large diameter seat tube helps the 'core-stability' of the frame but large, stiff seat posts don't help rider comfort. A 27.2mm post helps to dial out road-buzz and the smoother ride means you stay fresher for longer.

Disc Brakes

This frame is designed for disc brakes. They work consistently in all conditions, pull up quicker in the wet, they don't grind your expensive rims into black sludge and in my experience they change the whole riding experience for the better, especially when coupled with modern disc-specific wheels and high-volume tyres. You’ll find yourself riding in a more confident, controlled, fluid and ultimately more efficient way.

Internal Routing

We route the hoses and cables internally where practical, keeping the 'adventure nature' of our bicycles firmly in mind. For smoother runs and a cleaner aesthetic, all control cables, hoses and electronic shift control wires now run through the down tube, via the special BB shell and out through the chainstays, guided by our Mason 'MultiPort' adaptable inserts. Interchangeable Internal routing keeps the control cabling away from road dirt and grime, helps avoid accidental damage, makes cleaning easy, de-clutters your bike and means you can adapt your bike easily to work with various shifting and braking methods. For adventure and endurance riding, internal routing also has the advantage that it is easy to strap frame packs to the frame tubes without being hindered by external cabling and hoses.

Integrated Headset

Integrated, 41.8ø upper, 51.8ø lower, for taper head tube. Both bearings are ‘ACB’, meaning ‘Angular Contact Bearings’. The head-tube seat angle is 45º.

The headset drops into a tapered seat in the head tube and is tensioned using a headset tensioner within the fork steerer. Tensioning the headset centres it on the taper and prevents any play. The larger lower bearing allows a tapered steerer and larger crown. This gives sharper response, helps reduce flex under braking and spreads bearing load.

FlatMount Brake Calipers

Flat mount disc-brake callipers are lighter, neater, and open up more space within the dropout area for racks and ‘guards. The calliper is mounted to the dropout, allowing us to use a lighter, more comfortable seat-stay.  Up front, the calliper is mounted directly to the fork [via the brake manufacturers adaptor] and offers a cleaner and more minimalist appearance and also provides a compact packaging of the brake caliper.

Custom Tubeset

We choose each tube individually, considering the influence that it will have on ride quality and overall performance. We will use a blend of tubing types, custom shapes and bends to help us achieve this goal.

Modern metal frames draw on many of the design influences learnt from composite frames, such as oversized BB’s, taper head tubes and switchable internal routing. Teamed with our properly designed carbon-monocoque forks, the contemporary Aluminium, steel or Titanium frame is a formidable piece of kit.

Structural FInish

3D-Printed Ti Dropouts

We were heavily involved in the development of the highly advanced Reynolds UK, 3D printed Titanium, thru-axle/flat-mount dropouts that we use for the BokehTi. The dropouts are extremely precise and lightweight and provide highly accurate and stiff axle retention. The interior is a highly complex structure, only made possible by using this advanced 3D ‘Additive Manufacturing’ process, internal ribs, gussets and guides deal with riding forces and guide internally routed electronic-shifting cables. Alongside the dropouts, we worked with Reynolds to create beautiful new double-bend and tapered titanium chain stays. The stays mate perfectly with the dropouts and combine to give us the huge tyre clearance and smooth propulsion that we require.

For you this means perfect alignment and extremely efficient power transfer, helping to give the BokehTi it’s incredible ride quality and ultra-distance, terrain conquering mastery.

Switchlever

This model uses SwitchLever Thru-Axles front and rear. This high quality axle system features a removable lever to be used with both axles. Store the lever in the front axle for quick use or remove completely for extra security and a clean, low-profile look.
