Boost - What's it all about?
OK, this Boost stuff can get a little confusing. The lowdown is that all our MTBs are now Boost equipped*. The previous versions of the Ripley and HD3 used a standard 142mm rear axle but they now all ship with boost. The new Boost standard uses a wider hub flange, 148mm on the rear instead of 142mm and all the extra stiffness that brings with it. Boost has also come the the front of the bike, with a 110mm front axle rather than the 100mm standard. Again, the stiffness benefits this brings, amongst some other stuff, make the faff of changing over from the old standard to Boost worthwhile. Otherwise we wouldn't have done it!
*That's not to say there aren't some non-boost models still out there (we're pretty sure you'll still manage to have great fun on those bikes too).
All Mojo 3s are boost. We didn't have any Boost Fox forks until recently (which is why we shipped with Pike). Now we're shipping with Fox Boost forks standard. Note that these are NOT Plus forks but Fox has approved the clearance numbers for the 2.8 plus tyres we are using.
Boost and Plus for the Mojo HD3
With the addition of an all-new swingarm design, the HD3 is now both Boost and Plus tyre compatible, accommodating the delightfully grippy Plus tyres up to 2.8”.
With the addition of Plus capability, you can build the HD3 in three distinct categories that will accommodate wildly different conditions and styles of riding, all with a single set of wheels.
Our dw-link suspension effectively decouples suspension travel from climbing performance, so if XC or light trail bike duty is what you’re after, a nice light set of 2.3” tyres will turn this beast into a svelte shredder.
If you ride in mud a lot, some 2.3 mud spikes will fit with gobs of clearance.
For those of you who just want to point it straight downhill or if you ride in very rough and rocky conditions, put on some 2.5s with good sidewall protection and hold on tight.
Hint: if you want to use every mm of the 150mm travel HD3, the new Wide Trail (WT) Maxxis Minions are an ideal match for our 35mm internal width carbon rims.
And finally, the new kids on the block, equally confidence inspiring for beginner and expert alike, the 2.8” Plus tyres from both Maxxis and Schwalbe offer levels of grip we’ve never seen this side of Velcro.
It's easy to tell the Boost from non boost swingarms on the HD3, just look at the seatstay where the widest part of the tyre is, and you'll see it's notched out for clearance.
That’s Not All
For current HD3 owners who want to upgrade to Boost/Plus, we’ve got great news. Ibis are offering a (limited edition) swingarm retrofit kit for the 142mm HD3s to convert to the Boost/Plus swingarm.
The retrofit kit consists of:
- All new HD3 Boost/Plus Swingarm
- New 148mm Hexle
- Boost lower link
- Boost lower link rear shaft hardware
- Boost compatible front derailleur mount
- Retrofit kits will be available in April.
The Ripley and Boost
The Ripleys now ships with boost. To tell a boost from non boost Ripley, the easiest way without taking the wheel off is to look at where the derailleur port is at the bottom of the seatstay. If it's very close to the dropout, it's a non boost Ripley. If it's up about an inch from the dropout, it's a boost.
