Axle Note: QR stands for standard quick release axles. For thru axle/boost, the 12mm/15mm maxles are not supplied, as this is specific to your frame and fork. For QR wheels, standard QR skewers will be supplied.

DT Swiss Champion Spokes: The DT Swiss Champion spoke is a classic all-rounder for everyday use, offering DT Swiss quality and reliability. Made from X5 stainless steel, containing chrome for rust resistance and nickel for strength. The rolling of the nipple thread removes no metal from the spoke and preserves the grain of the material, maximising strength and greatly reducing the likelihood of failure at the threads.

Review

Great quality wheels

I purchased these for my Vitus Nucleus 27 VR and there is a stark difference compared to stock ones. The freehub sounds miles better and I suspect there's slightly less rolling resistance. The only thing I would mention is that the rims are slightly narrower compared to the original ones - not sure if that makes a difference or not.

a very good service

I bought this set of wheels for my MTB bike,but I wasn’t sure if they these are correct wheels for mi bike. I contacted madspeed7 team through their chat and they were very friendly and helpful. The answer came in les then 15 minutes as they promised even during a weekend. The wheels came also pretty quick. Thank you Madspeed7..

Excellent

These were bought (July 2024) to refurbish a 2017 Cannondale 27.5” mountain bike (quick release, non-boost, 135mm O.L.D (rear), 146mm axle (rear), 8 speed, HG cassette, previous wheels- Etrto: 584x17).

The quality of the new wheels are excellent - strong, balanced, and roll forever once secured in the bikes’s dropouts. Cornering is much improved with the wider rims (25 upgraded from 17). The freehub sounds very healthy, although the part number is not clear beyond the Koozer Xm490 hub shell reference, or is the appropriate method for extracting the freehub - should a replacement be necessary

There was an initial compatibility issue at the installation because it appeared the rear wheels’ axle was only equal to the O.L.D. of the bike’s frame, but this was because I had not realised the necessary extension attachments were still connected to the protective transportation axle covers.

Seating my tires (2.3” and 2.25”) was a nightmare, but this was an issue with my technique.

Apart from minor setup complications (relating to my knowledge) I am very satisfied with the purchase, and build quality, and appreciate Madspeed’s detailed information on the website, and - more importantly- their provision of an option to upgrade an older bike.

Nice wheels

Easy set up. Tubeless tires seated first time.
Wheels don't seem to spin freely, bearings a bit grippy - may just be bedding in?
Very satisfied overall though.

Good wheels

Good solid wheels Took tubeless tires no problem with the first inflation. About 150 - 200 g heavier then the Mavic crossride wheels I had previously however the Mavic wheels were 24 spoke and had continual problems. Size of nipples it’s slightly wider than a standard wheel, but this is not a problem as it only requires a different spoke tool, and the wheel has 32 spokes

Easy to fit the cassette and the free hub is fairly quiet. Overall I thought that the wheels were very good value though a little expensive, however I think that they are more solid than the Mavic wheels and will last longer. I have previously bought wheels from this company for an electric bike with 26” size and these wheels took extreme punishment over rocks slate and rough terrain at speeds in excess of 30 miles an hour. If these wheels I have just purchased Are strong (and it looks like they are) I will be delighted

Why Our Wheels?

If you're looking for quality wheels that are genuinely hand-built to a high standard, without the hand-built price tag, you're in the right place. Every wheel is backed by our no-nonsense 1-year warranty and lifetime support.

1. Hand-Built Wheels

We’re passionate wheel builders, and all our wheels are genuinely hand-built with care, allowing us to pay close attention to every detail of the build.

Each spoke is carefully tensioned to ensure even and consistent tension across the entire wheel, creating a strong, stable and reliable wheel designed for long-term performance, durability and reliability.

During the build process, each wheel is stress-relieved several times to help the spokes settle correctly. We also carefully check the dishing to ensure the rim is correctly positioned and centred over the hub.

2. Quality Components

We use quality rims, spokes and hubs, which are carefully sourced and selected for durability and reliability. Depending on the model, we use components from trusted brands such as DT Swiss, Pillar and Shimano.

3. One-Year Warranty & Lifetime Support – Complete Peace of Mind

We are extremely confident that you’ll love your new wheels and your experience with Madspeed7. However, in the rare event that you experience an issue within the warranty period, simply contact us and we’ll be here to put it right.

Our support doesn’t stop there. We offer lifetime support, with spare parts available for our wheels should you ever need them in the future.

With Madspeed7, our commitment doesn’t end with your purchase or when your warranty expires. We’re here to support you for the lifetime of your wheels.
