+How much to pack
For multi-day mountain biking and off-road touring the knack is to travel light, but safe. On technical singletrack in particular excess weight becomes quite a handicap - requiring both increased skills and effort. So pack smart.
  • Lightweight bike-specific rainwear goes without saying. 
  • The ‘killer app’ is a modern, lightweight, low volume down sleeping bag. The Sea to Summit Traveller has 200gm fill. An adequate rather than cosy pit for the night but weighs just 400gm in total and occupies a paltry 1.5 litres in your bag.
  • A lightweight down or primaloft jacket comforts you around the hut or campsite, and extends your lightweight sleeping bag if the nocturnal temperature sinks a bit low.

Time of year, terrain and availability of huts all impact on your selection but on a two day-one night summer mtb trip you should easily be able to stash all your food, clothing and emergency kit into the Ortlieb Seat Pack/Handlebar Bag combo. You may choose to supplement those with a small daypack to carry a water bladder, lunch, snacks and evening meal. Check out the Weight Watcher’s Equipment Guide for more.

+Fitting to your bike
  • The weapon of choice for bikepacking is a 29er hardtail. However plenty opt for a dual suspension rig. Either way you'll want to invest some time mounting your bags securely to your bike. Generally they stay glued to it for the duration of the trip. You get to lovingly pack and extract your gear at the start and end of each day.
  • Before fitting, lightly pack both bags.
  • Upfront, take care to not tangle with brake hoses or gear cables. The roll bag hangs below your handlebar, so ensure it clears the front wheel when the front shock is fully compressed. Locking the shock out, limiting travel or increasing air pressure is invariably required.
  • Out back a minimum 170 mm clearance (irrespective of any suspension) is required between your back tyre and the bottom of your seat rails. If you’re riding a dually, also check that the under-seat bag clears the rear wheel when the shock is fully compressed. The best remedy is to pump up the shock to limit travel.
  • Under-seat bags are not compatible with dropper seat posts. If you have a dropper either swap out for a standard post, or refrain from using it with the bag attached.
+Packing tips
  • Take time at the start of each day to stash your gear thoughtfully. Create a solid platform to stack the lighter stuff on. And minimise any voids. This maximises your load capacity and prevents the bags from shuffling and jiggling around on your bike.
  • The Revelate Terrapin under-seat bags has an air valve to let you to roll it tightly closed.
  • The Revelate Sweetroll and Saltyroll allow access from either end. In the ideal world you separate your gear so that at least one bag (normally the 'handlebar') remains packed all day. Leave ride food and clothing at the top of the other bag, or in your daypack.

  • Items are generally packed and sent the same day your order is received.

      A good solid bag and mounting. Requires care with packing to get nose of bag solid top stop bag bouncing onto rear wheel. This is only a problem with extremely hard offroad riding including jumping.

      Lives up to the hype!

      I purchased this from the high end of the bikepacking gear pool because the seppos rate these Alaskan-made bags so highly. A couple of loaded overnighters and it certainly lives up to the hype. Very well designed and constructed, completely waterproof, stuff off the bike and easily strap into excellent harness, and no tail wag. Thanks GroundEffect for bringing this brand south and for mailing to Aus super quick.

      Fantastic Saddlebag

      I brought this saddlebag as a replacement/upgrade to a cheaper Chinese model I had previously. The Revelate Saddlebag is really well made and secures really nicely to the seat. So far I haven’t had any problems with the bag bottoming out on my tire with rear suspension and love the design. Ground Effect were awesome to deal with and the saddlebag was delivered within two days which was amazing considering it was in between the Christmas/New Year period. Would recommend getting this bag via Ground Effect to anyone in the future.

      Handled the Old Ghost Road well

      I received the bag a couple of weeks before doing the Old Ghost Road. I trialed it on the Twin Coast Trail, and it went well, but the real test was to come. I am happy to say that it went well. Very stable, and fitted in a lot of gear. Also easy to attach, and the bag was simple to pop out at the end of each day. Definitely recommend.
