Backcountry Research Mutherload Strap
Pricing
The NEW Mutherload maximizes all the benefits of our dual-shockcord retention system with the versatility and adjustability to mount what you want, where you want it, anywhere on your frame. This strap will flat out stick like poo to shoe over the most demanding XC/Enduro race courses and trails anywhere.
Super lightweight and constructed with rugged materials, you have two choices on how you can have your strap built-up. You can go with our bomber thick sliced Hypalon (in black only) or you can choose to go in style with over 50 patterns and colors to choose from...your call.
To Load: Simply center the 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: Frame your bundle where you want it with the tube and shock cords facing the frame. Feed the slack end through the contoured loop and reef.
Sized to fit 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.

Orders are taking longer to process and deliver due to the challenges we face with the Covid-19 pandemic. Items that are showing as 'In stock supplier' should take around 5 to 10 working days to arrive. Please only place your order if you are not in a particular rush. If you choose DPD we will prioritise your order and will try our best to get your order delivered to you within 5 working days, although this is completely determined by the speed of the supplier and outwith our control. It is not unusual for a few orders to go over the 5 working days. Orders for Hope items are taking the longest at the moment with a turnaround time of 2-3 week unless stated as 'In stock for Immediate Dispatch' in which case it would be dispatched very quickly. Our phone lines are temporarily closed to allow us to work more efficiently and get your orders out the door. We are aiming to respond to emails the same day or in the evenings. Thank you for your patience and understanding during these strange times. Stay safe and stay positive!
If you need an order quicker than this please email us with the product ID to find out if this is possible to avoid disappointment. Items that state 'Remote warehouse' can take a little longer than the above estimates. International orders to Europe and the rest of the World take around an extra 3 working days. We will email you as soon as the order is dispatched.
How much is delivery?
Delivery is FREE to the United Kingdom on most items over £40. Just add the item to the basket to confirm the postage price for your order, and you can always remove it again.
What about bikes?
We aim to dispatch all bikes within 5 working days, but during busy periods we may have a few builds in the queue and could take a bit longer. If this is a concern or you need the bike before a certain date then please email us to make sure we can achieve this and avoid any disappointment. We will email you the day of dispatch and you can expect the bike the following day. If you provide a mobile number on your order the courier will also send you a text message 1 hour before delivery so you know exactly what time to expect it.
Who do you use to send orders?
We use Royal Mail for most of your orders unless they are bulky or valuable, in which case we will send the order using DPD. You can also specify DPD at checkout if you prefer to have your item delivered with an hours notice in the form of email or text from the courier.
