Mahi Mahi disk brake J-bend wheels

from £846 / pair

In-stock options for fast delivery. The Mahi Mahi disk wheels offer a perfect balance of light weight and power-saving aerodynamic profile. Our in-house hand-built quality, high performance hubs and Sapim CX-Ray spokes add up to an unbeatable wheelset for racing or all-round riding, on or off-road.

Centre-lock J-bend hubs offer a lower price point, reliable larger bearing and a more traditional look than our straight-pull wheel sets.

Description

The Mahi Mahi disk range also has options for rim depths from 30mm to 80mm for riders looking for either lighter weight, or greater aero benefits.

A disk-specific design allows for optimised aerodynamics while the low weight is an important part of the lively, responsive feel and streamlined performance of these wheels in all weather conditions. As with all our wheels they are handbuilt by us in our York workshop for perfect build quality every time and customisation through our choice of hubs and spoke nipples for the perfect fit with your bike.

The rim width is 22mm internal, 30.5mm external optimised for best aerodynamic performance with tyres measuring around 25-27mm. The width allows for lower tyre pressures without increasing rolling resistance – we recommend 60-80psi for most riders.

The Mahi Mahi disk rim is the result of 3 years’ development with our rim supplier including several iterations of rim design to perfect the tubeless fit. With 15 years’ experience of building tubeless wheels it was important for us to use a rim which offers easy tubeless inflation and maximum tyre security as well as strength. The result is a semi-hooked sidewall design which fits tubed or tubeless tyres securely and easily and offers greater impact resistance than a standard hooked bead. Unlike hookless bead rims, the semi-hook bead is suitable for running tyre pressures up to 100psi with 25mm tubeless tyres (though we recommend lower pressure for better ride quality)

Long term reliability, strength and meticulous attention to detail is standard on every wheelset we build. At the heart of this is our JRA hubs, with variants to fit any bike but all sharing the same light weight, ultra smooth and durable TPI bearings and reliable 6-pawl double-sealed 48-point freehub design. Building all wheels by hand in-house means quality control is built-in to every wheel with each component being checked as the wheel is built so we can achieve very close to zero returns.

Rim options

30mm rims are our lightest weight wheelset with good aerodynamic performance. These wheels are light for hill climbing but roll fast on the flat too.

40mm seems to be the sweet spot for most riders and with a weight of just 1433g per pair and almost totally unaffected by side-winds we recommend them for anyone.

50mm wheels are very fast with great aerodynamic performance at the expense of a bit more weight. These are the deepest rims normally used on standard road bikes.

our hubs

Just Riding Along wheelsets are built around premium quality hubs from Bitex in Taiwan. We have used these hubs on all of our own-brand wheelsets since 2014 with proven reliability and durability.

warranty

All wheels include a 5 year warranty on hub shells, and 3 year on all other parts.

Bearing wear is not included.

drive

6 pawls in 2 groups engage the drive ring inside the hub shell. The groups are offset slightly to double the points of engagement (POE) for a fast response to pedal input. M-type hubs have 54 POE, R-type hubs have 48 POE.

about your wheels

ready built wheels

This wheelset is built in our workshop in advance so you can receive it quicker. We normally despatch the wheels in 1-2 days and you should receive them the next day.

what’s included

  • Wheels are set-up with the axles and freehub you have selected.
  • All wheels have tubeless tape applied.
  • There are no additional parts provided.

build quality

During the building process all components are bedded in, stretched, and tensioned repeatedly so the wheels won’t go out of true. We inspect, check and finish every wheel with equal care.
