Backcountry Mutherload Strap – Accessory Review

Backcountry Research Brings Us The Mutherload of Straps

The Mutherload Strap from Backcountry Research provides a strong and versatile system to mount what you want, where you want it, anywhere on your frame.

Super lightweight and constructed with rugged materials, the Mutherload Strap is a simple yet very effective solution to securely strapping essential gear to your bike, and lighten the load in your pack.

Backcountry Research are a relatively small brand based in Bozeman Montana and have been making ingenious little gems like this since 2008. Backcountry Research have grown their brand slowly and solidly over the years through word of mouth. 2017 saw them co-sponsor the Yeti/Fox World Enduro team, equipping riders like Richie Rude, Cody Kelley and women’s pro-rider Anne Galyeanand.

First Impressions

There’s no denying, the Mutherload Strap is one tough cookie. Made from #92 industrial UV and rot resistant bonded polyester thread, you could literally hang a car off this thing. So don’t ever fret about it coming apart anytime soon.

The strap features a velcro tab section,  two rubber like shock rings and the whole package only weighs around 42 grams. The best designs are sometimes the simplest ones.

In terms of colours, we opted for a stealthy (some may say boring) black colour option but the Mutherload Strap comes in about 50 colours and creative patterns to choose from.

To set up is quick and pain free. Although on our first set up we did put it on slightly wrong, so the installation video was very useful, we’d recommend you watching that first.

To Load

Simply centre your inner tube on the grip-strip and pull the dual shockcords up and over the ends of the tube to lock it down…flip it over and slide in your choice of inflation, multi-tool or levers.

To Mount

Position your bundle where you want it on the bike with the tube and shock cords facing the frame. Feed the slack end through the contoured loop and reef tight.

Carrying Capacity

The Mutherload Strap has been designed to take a standard 26″, 27.5″ or 29″ tube by itself or with 1-2 16g cartridges, 1-2 20g cartridges, 1-2 25g cartridges, multi-tool, mini pump, levers or whatever combo you want. In our test we packed a 29″ tube, a 25g CO2 cartridge and two tyre levers.

Out On The Trails

Any strap system must only really pass one or two very simple tests. How much can it carry and does it stay put. Meaning, will my gear fall off at the first rock garden I hit? Well, in terms of how much it can carry, it’s pretty basic but these are essential items we are talking about. So we’re all good with only having 3-5 items. Any more and we’re heading into pack territory.

In regards to does it stay put. Well, yes it does. The Mutherload Strap has the gripping power of a barnacle on steroids. It just doesn’t move, at all! On rocky terrain, all day rides, it never budged. Un-mounting is a breeze and you can simply throw it your kit bag with all the items still attached.

On those crusty, wet and muddy rides it will get covered in grunge but washing the strap is easy. We just took it into the shower and got it lathered up and the drying time is pretty swift so it’s ready to go again in no time at all.

Born and grew up in Wales but now a fully fledged Aussie. A passionate mountain biker, hiker and general nature addict. I'm also a bit of a muso and enjoy a good craft beer every now and again (probably too often).

I hope what we do here at Tyres and Soles will inspire people to get out there and experience first hand, the natural wonders that surround them. So, pump up those tyres, don your favourite boots. Grab a mate, a partner, a pet… and head out into nature. But tell us all about it when you get back.

Aimed at the enduro and all-mountain crowd, with a superior fit and construction to most other flat pedal shoes on the market. The @ridecncpts Powerline is a shoe that is very hard to beat. 🤟🏼 Read the review in our bio link. | Photo credit: @seaninthedirt | Rider: @instarrdan

  • They’re baccccckkkkk... The Loam Grips are back and fully stocked (just like questionable 90s fashion, but better!)
  • Whether you're going for a day trip or a week of adventures, The North Face Base Camp duffles are roomy enough inside for all your gear. Just keep on cramming kit in there and you'll be surprised how much you can get into this is the iconic, super tough expedition duffel. 📸 @richardmcgibbon
  • How do you carry your junk? @allmountainstyle seem to have it all wrapped up with their OS Strap. 👍🏼 | 📸 @richardmcgibbon
  • Threading our way through to the weekend with the @monsroyale MTB gear.🤘🏼 📸 @richardmcgibbon
  • The Leatt DBX 3.0 is one of the safest mountain bike helmets in the market. What’s protecting your noggin today? 🧠 | 📸 @seanmurr123 / @seaninthedirt
  • The weekend is one more sleep away. What are your plans? 😛 | 📸 @richardmcgibbon
  • The @granite_design ROCKnROLL is a perfect companion to take on those longer rides where a trailside fix is crucial to getting you home. The whole package weighs only 136g, so adding it to your pack or hip belt is low-cost in terms of weight, considering the ROCKnROLL has all the bits that you'll need to do your trailside fix. Now you can live the ROCKnROLL lifestyle you've always dreamed about!
  • Wow! Pretty much sums up what we thought of the @hentydesigns Enduro Backpack. If you're intrigued by these new age bum bags then have a read of our review on our website. | Photo credit: @richardmcgibbon

There is a concern that eco-friendly products are not as effective as non-eco products. We have to call bullshit on this. The WPL range of lubricants is as good, if not better, than any non-eco friendly product on the market. best of all it doesn't harm the environment or you! | 📸@richardmcgibbon | #lube #lubedup #silkysmooth
  • With so many hydration gels, tabs and powders out there, it can be a little bewildering which ones to choose. We all have our favourites and over the years we tend to stick with what we know, so when we discover a new brand, we’re a little reluctant at first to go and spend our hard earned money on something that we don’t know will work for us, but after reading about @hdxmix story and the founder behind it, we must admit, we got very interested, indeed. 📸 @richardmcgibbon
