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.

The rim is 22mm wide internally, with an external 30.5mm width optimised for best aerodynamic performance with tyres measuring around 25-28mm. The large width allows for lower tyre pressures without increasing rolling resistance – we recommend 60-90psi for most riders. Rim depths are 40mm or 50mm for either lighter weight, or greater aero benefits.

The Mahi Mahi disk rim has a hooked bead sidewall design which fits tubed or tubeless tyres securely and easily and offers excellent impact resistance, making it suitable for road or gravel. This rim design is suitable for running tyre pressures up to 100psi with 25mm tubeless tyres where the tyre specs allow (though we recommend lower pressure for better ride quality).

hubs : JRA centre-lock or 6-bolt hubs, Straight-pull or J-Bend
rim : JRA Mahi mahi carbon rims, 24 or 28 hole with water transfer decals
spokes : Sapim CX-Ray black spokes
nipples :  choose from brass or aluminium coloured nipples
weight 40mm: Centre-Lock Straight-Pull pair 1482g (front 677g / rear 805g)
weight 50mm: Centre-Lock Straight-Pull pair 1556g (front 719g / rear 837g)
freehub: Shimano 11 or 12sp, Campagnolo (including Ekar 13sp option) or Sram XD/XD-R freehubs, Microspline

40mm is a good all-round depth and with a weight of just 1490g per pair and little affect from side-winds we recommend them for anyone.

50mm wheels are very fast with great aerodynamic performance at the expense of a bit more weight, around 30g per rim. 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.


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

Bearing wear is not included.


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 6.7 degree, 54 POE, R-type hubs have 7.5 degree, 48 POE.

about your wheels

custom built wheels

This wheelset is built to order. We hold most parts in stock and build them after you have ordered. The build time is advertised on the front page on under the title.

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.

handbuilt in the UK

We built the wheels in our York, UK workshop.
