DCR Big Boy / Full Volume Wheelsets

The DCR Big Boy and Full Volume wheelets set a high standard for MTB wheels. Available in 30mm (Big Boy) or 35mm (Full Volume) internal widths, these wheelsets offer incredible tyre profiles and the strength to withstand the punishments off road riding. 

Prices from £460. Demand for wider rims has been met here. Extra width means extra air in your tyres – that means greater comfort, lower pressure and better grip.  Should you wish, you can still run a cross country tyre on these rims, however the profile was developed to meet the needs to harsher terrains and endurance riding. Just like any wheelset from DCR Wheels, you can customise hub colour as well as freehub body and axle length. Hard or heavy riders should choose the 6-bolt hubs for their extra strength and durability. We have all the parts in stock to build this wheelset. By using the link below, you will be entered into our build queue. If you require the wheels urgently, please enquire about lead times or select a wheelset that is already built and ready for dispatch.

Strong, Light Rims With 30mm or 35mm Internal Widths

The DCR Big Boy (30mm) and the Full Volume alloy (35mm) rims offer excellent MTB tyre profiles including plus-size (2.5″ and above). They both have a welded joint, an extra tough spoke bed, competitive weight and nice matt finish owing to a shot blasting and anodising treatment (anodised internally and externally), they have a rider weight limit of 120kg and a spoke bed that has been tested to 300kgf. There is a bead locking system and 1.2mm hook for compatible with all road tubeless and tubeless ready road tyres. Their internal profile and deep central channel ensures easier installation and removal of tyres.

Spokes And Nipples

The Sapim CX-Ray spoke is the obvious choice to keep weight down, improve ride quality and retain a high level of lateral stiffness. Using Sapim’s alloy nipples and our nipple/spoke prep means that even in all year round use alloy nipples are still a sound choice. We provide a lifetime warranty on the build/spokes on this basis. Changing your hub colour or the spoke count to can be done without any additional charge.

Critically the CX-Rays are highly durable and a lot more stable than round spokes.  This comes from a combination of the spoke gaining strength through the flattening process, additionally the spoke being flat allows it to be adjusted with far greater precision.  A round spoke will twist when you turn the nipple, which the builder must take into account. An aero spoke can be held steady allowing for much smaller adjustments.  Spoke twist is a problem which persists particularly badly in the Laser spoke (light gauge, round) and can cause difficulty during servicing in later life.  Where the Sapim CX-Ray is immune to spoke twist, you can service it for a far longer. 

As before, the set comes with our own brand centrelock or 6-bolt IS hubs with their weather treated bearings for high performance and excellent longevity/serviceability. They have fast engagement (48pts for centrelock, 54pt for 6-bolt IS). Boost hubs are also available for this wheelset but do incur an additional charge.
