Internal Cable Routing

The cables are routed through thin stainless steel guide tubes, which run the full length of each internal portion. Rear brake and derailleur cables run internally through the down tube, then externally below the chain stays for the remaining distance. Stealth dropper post cable routing runs internally through the down tube, and directly into the base of the seat tube. The front ends of the cables are sealed to the stainless guide tubes, so that water and dirt cannot enter the frame.

Integrated Seat Clamp

An integrated seat clamp keeps the bike as simple and secure as possible, and complements a dropper seatpost nicely. The clamp requires a 5mm allen key to release and tighten.

Custom Head Badge Text

Custom head badge text allows you to add a line of text to the head tube badge on your frame. Add your own name, your preferred beverage, a short message about Strava or carbon fibre, or even your favourite film, to personalise your bike. Maximum of 11 characters; A-Z, 0-9.

Chain Device Mount

If you want to run a chain device, you need to have an ISCG05 mount. The mount can support a bash guard, or only an upper chain guide, or a full chain device with integrated bash.

More information

Bottle Cage Mounts

BTR bottle cage bosses are stainless steel, and ‘blind’ (no through-hole). This means that they not only work flawlessly as mounts, but also ensure that the frame isn’t compromised by their existence – even if you leave them open. Each pair (for one bottle cage) costs £20.

Bottle Cage Locations:

  • First cage – top side of down tube
  • Second cage – front side of seat tube
  • Third cage – underside of down tube

If you need to relocate a bottle cage, please contact us before placing your order.

Front Derailleur Cable Routing

If you need more than 500% gear range, we can still equip your frame with cable guides for a front derailleur. Note that these guides are always external, even if all other cables are internally routed. The cable will be routed on the underside of the top tube, and to a fixed stop on the back of the seat tube above the derailleur.

Standard Frame Colours

Standard frame colours are included in the price of a frame. Please refer to the Frame Colour Chart. Please note that the clearcoat (raw) frame finish is no longer available, as of December 1st 2018.

More Information

Special Frame Colours

Special frame colours may incur a surcharge above the £60 included, due to multi-coats and powder costs; this can be up to another £60 (£120 total). We’ll inform before commencing work on your order if there is any additional charge to be paid.

Custom Decal Colours

Custom decal orders will receive a spare set of decals. Please refer to the Custom Decal Colour Chart.
