Description

‘The first thing that struck me is how direct and precise the BF37/31 wheels felt….’ Singletrack review 07.12.2018 – read the full review HERE

37mm outer and 30.5mm inner width asymmetric rims, these are perfect for riders running tyres between 2.2 and 2.6 width. Tough light wheels that will give huge improvements to the feel and handling of your bike – so much more than just the weight saving in comparison to alloy rims.

Approx. wheelset weights:

With ERASE hubs  (our lightest wheels)   27.5 Sapim CX Ray: 1620g;      27.5 Sapim Race: 1710g;       29er Sapim CX Ray: 1690g        29er Sapim Race: 1780g

With HOPE Pro4 hubs:   Add 100g to ERASE wheelset weight

With Industry Nine 1/1 hubs: Add 80g to ERASE wheelset weight

With Industry Nine Hydra Classic hubs: Add 45g to ERASE 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, ERASE and Industry Nine hubs, which we believe stand out from the crowd and each 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.

Standard wheels are built with Sapim Race 2.0-1.8-2.0 double butted spokes which are wider gauge than most competitors build with but are up to the job for the type of riding these wheels are built for and do not snap.  If you would like the same strength at a lighter weight, choose Sapim CX Ray spokes for an approx. 90g per wheelset weight saving – the most expensive and fatigue resistant spokes on the market.

We build these wheels with 32 spokes on the rear and 28 spokes on the front.

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

    Had these wheels for a month or so now, no need to mention the hubs really. The rims are very nice and clean looking. I went for the grey decals as pictured above and for me I like the understated/stealthy look of them. The wheels are very well made and came ready for tubless. Getting the tyres on wasn’t the hardest wheel I’ve ever encountered. No tyre levers needed and they inflated absolutely fine. The 37/31 leaves a nice shape to the tyres (magic mary & high roller)

    On the trail they are very different from the stock wheels that came on my nukeproof. Obviously stiffer, the acceleration and cornering has been transformed. Front end is very lively now the turn in is quick. I’m very happy with my wheels and I look forward to years of abuse

    Absolutely fantastic wheel set, thanks, have survived countless poor line choices and bad landings, i’m not the smoothest rider!!! Spent a week riding downhill in the Alps with no issues whatsoever, all still true and running.
    Nice and Stiff and very easy to set up tubeless.
    Fantastic customer service as well.
    Thank you.

    after having several dealings with stuart over the years. he was my first choice for these latest custom wheels for a nomad 4 build. spec and ordering is simple with excellent communication. wheels are a work of art based around the bombproof hope hubs and very easy to set up tubeless. after 8 months of abuse they have had no maintenance and are still running mm true. you def will notice the diff on the trails with these wheels. in my opinion they have to be pound for pound the best wheels on the market. this guy has forgotten more about wheel building than most people know.

    Awesome wheelset. They’ve been hammered round the peaks, Wharncliffe and ‘Ard Rock all summer long. Set up tubeless, I have had zero issues everything is still tight and true, so glad I went for new wheels rather than new bike totally transformed the feel of the ride.
    Oh, and an absolute bargain to boot. Stuart was great from start to finish and kept me informed from point of order through to delivery, cheers fella!

    Fantastic wheels and great customer service. I’m a big guy at 15st and these wheels have really improved the ride quality of my Hightower. A great upgrade that I thoroughly recommend!

    Excellent build quality and look great. I’ve had them for over a year now on my hardtail steel 29er and given them a good hammering, still true and in great shape.

    I am now the proud owner of 2 sets of Blue Flow wheels – first up I got a set of the All Mountain wheels which have found their way on to my full suss set up; and now I also have a set of the lightweight xc wheels which adorn my ti hardtail! I have been riding the wheels for about six months now and they are holding up great. Straight and true and still look really nice. Stuart was also on hand to help decide on my wheelsets and gave me loads of useful advice to help guide my purchases. Highly Recommended!

    These wheels are fantastic, crazy strong, stiff and pretty lightweight. I’ve done over 2000 miles on my set and they’ve taken a decent hammering, I’ve managed to write off two reinforced tyres from rock strikes, the wheels still run as true as the day I got them! They only have a few small cosmetic scratches, other than that the look like new. I recently raced the Marji Gesick 100, this race has crazy amounts of rocks, roots, drops and is notoriously hard on tyres and wheels, I had no issues at all. Stuart was on hand to advise on wheel build, it was great, one of the reasons I chose Blueflow. I wouldn’t hesitate to buy another set!

    My only wish is if they offered different hub configurations, don’t get me wrong Hope’s Pro4 are bombproof. Just having recently had the chance to try I9 instant engagement hubs. I9’s on these rims would be awesome!

      Thanks Matt. We will build our wheels on any hubs at all by special request. We’re currently testing Erase hubs with 6 degree ratchet engagement and they are about 100g per set lighter than Pro4s. If things go well we’ll have them as website options by the spring but feel free to enquire beforehand.

    Great build, had these wheels for over 4 months now. These are my first carbon wheels set so i where a bit nervous with being a heavy rider. I emailed stu and he reassured me that they would be ok. I have had no problems at all. I do a mixture of riding from lakes rocky desents to up lift days. I Would have liked the option to upgrade the hubs as my last 2 wheels sets came with chris king and i9 hubs. Dont get me wrong the hope pro 4s are good but not as good as i9. Would definitely buy again.

    • stubowman (verified owner)

      Hi Andrew, thanks for the review. We’ve built wheels with Chris King hubs for customers and we can get I9 hubs as well. Just email for a price if you ever fancy buying another set ;o)

    Exceptional service coupled with and excellent wheel set. Ive run my wheels on my orange six for around a year. Great feedback, light and robust, can’t fault them. During the summer, Stuart spent time rebuilding mine replacing the hubs during my MTB bike rebuild.
    Again, Stuart pulled it out the bag, and rebuilt and returned to me as promised
    Highly recommend these to any one that’s looking for a great wheel set that they can rely on

    I have had these wheels around 12 months now and they are still as true as the day I received them. They cope with gaps jumps ad rock gardens no problem. With hope hubs, a good warranty and an excellent service via email I would certainly recommend to anybody.

    I have had these wheels now on pro4s for 2 years and given them a good hammering, some pretty hard casings on jumps and bottomouts roots without any issues. They are still as true as the day i got them. I have been through a set of bearing on the hubs so plenty of miles on them. Excellent A1!!

    Robbie Mackay

    Boom just like that 2.5 years are gone and these wheels are still absolutely superb. Other than the ocassional once round the spokes for tension they have been faultless. I’ve been through full drivetrain, suspension services and many tyre changes and the wheels are still true and strong. I recommend these wheels to everyone that asks about them and some of my friends now run a set. I’ve also let others try them on there bikes and they all are surprised by the difference you feel going from alloy to carbon. The pro4 hubs are solid and reliable and other than some pawl and springs had no issues with them either.

    If your hovering about the reviews trying to make your mind up, just buy them they are as good as you’ve heard
