Hot on the heels of the launch of the Mojo 3, Ibis has updated the longer-travel Mojo HD3 with a 148x12mm rear end that allows riders to run standard width treads as well as 27.5 tires up to 2.8in wide.

The new carbon swingarm can accommodate tires up to 2.8in wide:

The move to a 148x12mm rear end may be a matter of keeping current with the times, but designing it to also accommodate 27.5 rubber significantly broadens the scope of this already capable trail bike.

According to Ibis, a nice light set of 2.3in tires will turn the HD3 into a svelte shredder, 2.5in items with good sidewall protection is the ticket for straight-lining through rocky terrain, and 2.8in offerings from Maxxis and Schwalbe will maximize traction.

The ‘boosted’ HD3 is in stock and available for purchase immediately.

Ibis is also offering a swingarm retrofit kit, allowing HD3 owners to upgrade their current bikes.

The kit consists of:

  • Boost/plus-compatible HD3 carbon swingarm
  • 148x12mm Hexle thru-axle
  • Boost lower link
  • Boost lower link shaft and hardware
  • Boost compatible front derailleur mount

The retrofit kit retails for $899 / £699 / AU$ TBC. It’s available for pre-order now through Ibis’ online store. Kits will ship in April.

Ibis will also offer a swingarm retrofit kit for existing hd3 owners:

Backwards compatibility: what a concept!

To complete the conversion to a 27.5+ trail-slaying behemoth, HD3 owners may also need a new fork, a wider wheelset for 27.5+ treads, and a crankset and chainring with a 52mm chainline for the 148mm rear end. It’s not cheap, but it’s more affordable than buying a new bike — kudos to Ibis for developing a backward-compatible product.
