SKU: N/A Category:


With a 29.5mm external / 24mm internal rim profile yet weighing as little as 1450g for a 27.5 wheelset, our latest asymmetric XC wheels give the best of all worlds! We only build these with Sapim CX Ray spokes to give the lightest possible weight without sacrificing any of the strength. You will notice huge improvements to the feel and handling of your bike – so much more than just the weight saving in comparison to alloy rims.

Approx weights for wheelsets:

With Hope hubs:   27.5 = 1500g         29er = 1590g

With Industry Nine 1/1 hubs: Subtract 20g from Hope wheelset weight

With Industry Nine Hydra Classic hubs: Subtract 50g from Hope wheelset weight

Rims are constructed from unidirectional Toray T700 carbon and have a hookless bead inner profile. They are asymmetric to give closer to equal spoke tensions on each side of the wheel for an even stiffer, stronger wheel.

We build our wheels on Hope and Industry Nine hubs, which we believe stand out from the crowd and both with their particular strengths unmatched by any other brands – reliability, longevity and serviceability being a high priority with all designs. Our wheels are built to last and our choice of hubs reflects this along with our insistance on only using brass nipples.

28 Sapim CX Ray spokes make up each wheel. These are the lightest, strongest and most expensive spokes on the market used by the likes of ENVE and Zipp. How many other spokes on the market are light enough for carbon road wheels and strong enough for World Championship winning downhill wheels?!

One way to save further weight would be to use alloy nipples rather than brass and most lightweight wheels take advantage of this easy option at the detriment to wheel strength, serviceability and longevity. All of our wheels use brass nipples to prevent seizing a few years down the line. When we build a set of wheels we intend them to last for decades rather than merely years.

Until you have ridden with carbon wheels you cannot appreciate the huge advantages in handing and ride quality they offer. Stiffer rims improves steering accuracy, tracking and speed while the vibration absorbing properties of carbon smooth out your ride and your bike will ride noticeably quieter.

Prices include free UK delivery.

    Can’t say a word wrong about these wheels! They’ve really transformed my bike, making it not only a lot lighter — saved about 600grams on the stock set — but also a lot more lively and responsive. Noticeably stiffer than the stock set that came on my Merida Ninety-Six 9.7, they feel a lot more positive through the corners and the weight saving makes a big difference up climbs and accelerating through single track. The rim width and profile makes it very easy to seat tyres, and gives them a nice wider shape than a narrow rim, increasing the grip and comfort. The build quality and service from Stuart has been fantastic, I’ll definitely be back for another set when I need one! I’ll be racing with these at Mountain Mayhem 24 as a pair, and I have every faith they wont skip a beat.

    Given these wheels an absolute pounding in several tough races and events and they have performed faultlessly.

    The weight came up exactly as advertised and less than half the price of the Rovals they replaced also wider and tougher.

    The red hubs and graphics have drawn many admiring comments.

    Good quick and professional service and follow up.

    Highly recommended.

    Fantastic wheels that have transformed my bike. They are slightly lighter than those they replaced, but much stiffer, so they are more responsive and give better trail feedback, inspiring confidence and allowing me to better tune tyre pressures and suspension setup. Customer service has been perfect, investing time at the outset to ensure the right build for me, and communication throughout build and delivery so I always knew what was going on.

    Thoroughly happy. Bought a set of 650b BF30/24 wheels to go on a new build Ibis Hakka MX gravel / cross bike. Weight as advertised, excellent build quality and service. Good communication from Stuart throughout – from order, info on build queue, delivery and follow-up. Spare spoke in the box too.
    I added a second layer of tape to get the tyres to seat properly for tubeless inflation, but that’s down to the floppy Schwalbe tyres I’ve got. Just bought a second set of 42mm / 29er wheels for Stanton Switch9er ti and Maxxis HRs seated and inflated with no problems.

    These are fantastic wheels. I race in XC endurance 12 and 24 hour events, and I have added a set of these wheels to one of my bikes. They are not only as light market leading similar XC carbon wheelsets for half the price, but also come with the added confidence that they are built to last.

    I have a set of the lightweight XC rims built with a lefty set up for my Cannondale FSi race bike. I’m part of the Cannondale Asia team and absolutely love these rims. I raced them in numerous races in Asia in both marathon and XCO winning multi day stage races and stand alone marathon and XCO events. The rims have withstood some punishment and are still true and performing without fault. Absolutely love these wheels, they are superb.

    Great wheels, Hope hubs as good as ever, rims nicely light and stiff. Fitted to my TopFuel, measurably quicker on my favorite rides giving me my best times (and helping me to keep up with my fitter mates uphill !). Certainly recommended.

    A quick update after just over a year of XC racing, training and bike parks in all conditions – the wheels have been more than up to the test and haven’t missed a beat!

    I’ve been running these for a good year now and can’t fault them. They’re light, strong and much more reasonably priced than the big brand names. I like Hope hubs because they’re reliable, straightforward and easily adaptable – plus they look great – so, from my perspective, these are clearly the better option. Highly recommended.

    Stuart was really helpful from start to finish.I started looking for some carbon wheels to reduce the weight of my Whyte bike .All were way above my budget until I found Blue flow wheels, looked too good to be true.Read the reviews and bought them.Arrived in time to take them back to Spain.Fitted them and now I can climb the hills as fast as the guys with their expensive Carbon Hardtails. Lots of rocks and Goat tracks and after a year of weekly use still look like new. Good to be back with hope hubs as well. Thanks once again Stuart.

    Got the XC ones in January. Easy tubeless set up. Hope hubs make great noise. Used pretty hard without issue and I weigh 200lb. ..bought on a friends recommendation so thought was pretty safe anyway. Very good customer service so don’t be worried about asking for advice.

    I love these wheels, I have a set of 29er wheels, they take everything you throw at them. Build quality is amazing and they ride fantastic. Great value for money.

    super great wheels! I purchased a set of 29er’s with hope hubs. They are super stiff, quick rolling and take everything in their stride. I may sell the bike but the wheels are staying. Saving up for the next set!

    You will not regret buying these wheels, they will transform your bike!
    I have a 29er XC wheelset on Erase hubs, which I use for trail centre red/blacks and natural stuff in the Lakes. Even upgrading from a pretty light set of Stans Arch Ex and Hope Pro 4s I managed to cut over half a kilo from my Whyte S120. They were very easy to set up tubeless, with 2.3 Maxxis DHR front and Crossmark rear, after using some grease around the valves and seating with only a track pump. They look great with the colour matched graphics that Stuart kindly organised for me, and ride better! They accelerate quickly, give precise handling and are very smooth, holding their line well in rock gardens and on twisty single track. The only downside is having to wait for my mates to catch up after descents!

    The Erase hubs are light, free running and sound great (a turbo buzz). They have quicker engagement than the Hope’s and are lighter, though they only come in black – have matched to black brass nipples and CX Ray spokes so work for me. Throughout the build process communication from Stuart has been unbelievably good, with frequent updates and photos sent in advance of delivery. Finally, the rims come with a reassuring warranty and are competitively priced for a set of beautifully crafted hand built wheels.

    Highly recommended!
