Components, Blue Flow Wheels - Carbon Mountain Bike Wheels, custom MTB Wheelsets - Components Banner

All of the components used to construct our wheels have been carefully selected. Creating the best performing and most durable carbon wheels available at any price.



Our rims are made from unidirectional Toray T700 carbon, extensively tested in the lab and on the trail. We also offer the unique upgrade of a kevlar carbon weave outer skin on our 35mm All Mountain / Enduro rims.

The majority of riders will turn to carbon rims to save weight. However, for us, the absolute most important feature of a carbon rim is that you can trust it 100%. Also, you know it will not break. This strength also contributes to the stiffness which sets carbon wheels apart from anything that can be produced in alloy. We have achieved weights that are similar to much narrower rimmed comparably priced alloy wheels and on par with the highest priced similar width carbon wheels on the market.

Our rims all utilise hookless bead technology for extra strength and are supplied tubeless ready with Stan’s rim tape fitted. Tubeless tyres seal and inflate easily with a track pump and once they are on they do not leak.


We only build our wheels with Hope Pro 4 hubs for several reasons:

  • Sourced just up the road in the UK,
  • The most reliable hubs we know of,
  • Fantastically easy to adapt to different fitting sizes and freehubs,
  • All replacement parts are readily available now and forever,
  • Available in 6 different colours and they look amazing!

If Hope make them, we can build your wheels on them!

Components: Spokes & Nipples

DT Swiss Competition 2.0-1.8-2.0 spokes

Our standard wheels are built using DT Swiss Competition 2.0-1.8-2.0 double butted black hooked spokes. Double butted spokes save weight and allow for a little extra vertical compliance through the narrower middle section of the spoke. These spokes are extremely strong and reasonably light weight. We feel these are the best spokes for our wheels and the type of riding they are designed for without breaking the bank for the most exotic and expensive items.

Sapim CX Ray Spokes

We also offer the option to upgrade to these most exotic and expensive spokes if you desire – Sapim CX Rays. These save around 45g per wheel compared to the standard double butted spokes. They give the best results in fatigue testing compared to any other spoke on the market. These also give excellent vertical compliance at the same time as massive lateral and torsional stiffness. The only disadvantage to these spokes is their high cost and this upgrade adds £100 per wheelset.

Hooked and Straight Pull Spokes / Hubs

Most of our wheels are built with standard hooked spokes and hubs. We do offer straight pull spokes and hubs with CX Ray builds although this increases the price further due to both the hubs and spokes being more expensive. The strength, stiffness and weight differences between straight pull and hooked builds are negligible. The advantage to straight pull spokes is that the hubs look fantastic and really stand out.


We only build wheels with brass nipples as they are much stronger, harder and resistant to seizing over time when compared to alloy. We do get requests for alloy nipples but we will always attempt to talk customers away from this as these are much more likely to crack, round off and seize over a period of several years.
