If you’re looking for wider rims without the weight penalty but with all the handling advantages carbon rims offer, these could be for you. They are 42mm wide externally with a 35mm internal width.

Weighing around 1790g for a 27.5 wheelset with CX Ray spokes, they are a similiar weight to much narrower XC alloy rimmed wheels. These can be used with 2.35 tyres, are perfect for the next generation of Maxxis WT (Wide Trail) tyres and will also comfortably accomodate 2.8 plus size tyres. They are asymmetric rims to give more even spoke tensions on each side of the wheel for an even stiffer stronger wheel.

Approx. wheelset weights:

27.5 CX Ray: 1790g;      27.5 DT Comp: 1880g;       29er CX Ray: 1855g        29er DT Comp: 1945g

Rims are constructed from unidirectional Toray T700 carbon and have a hookless bead inner profile. Like all of our wheels, they are built on Hope Pro 4 hubs in your choice of colour and available in all sizes including Boost and with either freehub arrangement. Rim graphics are our white and blue as standard but you can choose any combination of colours to match your hubs and bike.

Standard wheels are built with DT Swiss Competition double butted spokes or you can upgrade to Sapim CX Ray spokes for an approx. 90g per wheelset weight saving and even more strength and durability.

Hope SP (straight pull) hubs are an option if you choose the Sapim spokes but these are not available on boost hubs. The main advantage of the SP hubs / spokes is the improved look. The weight and characteristics of the wheels are virtually unaffected.

Wheelset prices start at £679 with DT Swiss Competition spokes with the following upgrades available:

Sapim CX Ray spokes – adds £100

Straight Pull Hubs / spokes – adds £36 (only available with CX Ray upgrade and NOT on Boost hubs)

Prices include free UK delivery and we deliver to most other European countries for a small extra cost.

    i bought a set of these wheels from Stuart and i couldn’t be happier with them. The wheels in the pics are the ones i ordered and they look even better in real life than they do in the pictures and the performance matches the looks. I had a pair of 30mm 29er wheels on the bike prior to swapping to these and haven’t gone back the 29ers yet. I am running them with 2.8 maxxis rekons which are setup tubeless (tubeless setup was easy with these wheels) and are working well for me. I was very happy with the service i received from the first enquiry right through to delivery and would definitely recommend the wheels and blueflow to anyone looking for a great set of carbon wheels and fantastic service.

    After lots of research, I came across Stuart’s website and spoke to the man himself. Really knowledgable and passionate and happy to answer all my questions. The wheels were superbly built and made my already fab Ibis Mojo3 even better. They are the perfect width for running 2.8 chubby tyres and are definitely stiffer but somehow more compliant than the (again excellent) alloy Ibis 742s I replaced them with. Since then ridden a trouble free 1000km on all sorts of terrains and in a couple of bike parks. Not had to even touch them with a spoke key. Recommended

    Now I want another set for my FS 29!

    I looked at lots of options before I came across Blue Flow. The 35mm internals were exactly what I was after for wide trail tyres and the asymmetric build on boost Hope hubs creates a really strong and laterally stiff wheel. I was slightly concerned that being so stiff would make them feel harsh but this is totally not the case, so long as you get tyre pressure and suspension setup right they feel amazing. Stuart’s wheelbuilding and service is first class. I’ve been hammering the wheels for several months including regular Bike Park Wales trips and they’ve taken everything I can throw at them with just the odd scratch. Value for money is amazing and highly recommended.

    I purchased my 42mm asymmetric 29er wheels from blue flow around 6 months ago and I can honestly say I cannot fault them. I found Stuart really honest and great to deal with. If you need to ask a question he’s on it straight away with a reply by phone or email.
    The wheels are solid and set up great for tubeless. Just pop your tyre on with valve and sealant and your away.
    Bang on wheels ! Bang on Service !
