+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.

      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.

      Caution with clearances

      I have 190mm clearance from my saddle rails to the 3" rear tyre on my rigid 29er and I blew through the harness on the first ride through contact with the rear tyre. Despite constant attention, repacking, adjustment and care I simply didn't have enough clearance. My bag was the earlier model of the 14l terrapin and not bought from GE. Buyers should note that the clearances quoted on Revelate's website for this current bag are 8.5 inches or 216mm - which is more than 170mm quoted here. If you do have the clearance then the quality and functionality of my bag was awesome. And I have been buying from GE for a long time so I can tell you their service is great.

      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.

      Revelate terrapin 14ltr

      Great piece of kit, once I figured out how to out it on the bike. So easy to use and great quality.

      Works just as described

      I’ve just used my revelation terrapin 14L on a 3 day solo mission, and it has provided invaluable storage space. I put my clothes, stove and sleeping bag in the compression sack with ease, and I’ve not felt any wobbling or bouncing. Solid build and very ergonomic design.
