Frontier is our
hardtail mountain bike. Ride hard at the trail centre, load it up for a midweek bikepacking trip, pocket your passport and continue around the world. With full rack mounts at the back and multiple boss mounts on the fork, Frontier is an adaptable off-road explorer.
The geometry is for long day comfort but it’s no slouch.
The 6061 aluminium frame provides a durable and stiff chassis giving a responsive kick as you demand power when the slope steepens or enjoy feedback and precision through the corners.
Available as a fully rigid or with 100 mm suspension fork. Set it up for XC race speed or for all day big mile comfort.
Tyre clearance gives you the choice of 27.5+ or 29in wheelsets. QR Boost 141 mm rear spacing provide the benefit of stronger, stiffer and more efficient wheels.
The 6061 aluminium tubing is durable, light, low maintenance and stiff.
Internal cable routing
Clean lines and tidy cables thanks to internal routing. Frontier also incorporates routing for a dropper seat post.
Wide tyre clearance
Extra width between the chainstays gives you the choice of running 27.5+ tyres up to 3 inches or 29 inch tyres up to 2.4 inches.
Boost axle width
The Frontier frame is designed around QR Boost 141 mm rear spacing providing the benefit of stronger, stiffer and more efficient wheels. Seatstay mounted disc brake for clean lines and damage protection.
Responsive when loaded - Frontier is more than happy to shoulder a pannier.

The build kits we use are tried and tested. It's stuff we know just works together. But if you want to change any part of the spec ... no matter how small ... then get in touch. Any change is no problem. Working with you to create dream bikes means we've built some pretty special bikes along the way.
You can interchange Love Mud components on this build at no additional cost. So if you want a different length of stem, a particular saddle or bar then let us know in the notes section in the checkout and we'll get in touch.
We hold big stocks of SRAM, Rockshox, WTB and regular build with Shimano, Hope, Cane Creek. We'll build your Sonder with any part that suits your needs. Give us a call and we will help spec and build a Sonder. With the same experienced mechanic helping throughout your build you know who to call if there's anything you want to know.

Top value for money
Went over to see it and have a test ride. Bought one straight away. Built while I waited in 2 hours.
So cheap in all honesty. Forget all the boost wheel rubbish you read on line, its called progression. I went fully rigid and have ridden some very heavy stuff with it. Also used for touring and packing. I carry a lot as carry for two, no bb sway and as long as your not looking for 17mph average this thing will trick all day.
