I’ve been using the Road Runner Jammer bag for just over a year now and I thought I’d share my thoughts on how it’s been.
One of the benefits of being the owner of Velotastic is that I get the pick of the products that I sell to use when I’m out on my bike. It’s a great position to be in, but I have to be careful not to chose them all as it would cost me a fortune !
I’ve been using the Road Runner Burrito Supreme bag for a few years now. It’s a great bag, but I was after something a bit bigger for when I am guiding as I’m not a big fan of riding with rucksacks.
There’s three bags in Road Runners rolltop range – the Jammer, Middle Earth Jammer and Jumbo Jammer all with increasing amounts of capacity. I decided to go for the smallest in the range – the Jammer.
In the bag I can easily fit a survival bag, bothy bag, first aid kit, food, waterproof and extra clothes. On the external pockets I have some snacks, a whistle and a pocket to spare. This gets all this weight off my shoulders and onto my bike.
Fitting the bag
The bag attaches to the bike using three straps – two on the handlebars and one round the head tube. It’s very easy to swap between bikes. It can also be used as a saddle bag if you have suitable mounts but I’ve not tried that yet.
One of the things I did end up modifying on the bag are the bar straps. I’ve fitted Voile straps instead of the standard bar straps that come with the bag. I find these easier to fasten on and off the bike which is really handy in cold weather when you don’t want to take your gloves off.
I’ve not had any problems with the bag trapping any cables on either my gravel or mountain bike.
When the bag is fitted to the handlebars it tends to dip towards the headtube. With smaller frames this can be an issue as the bag may rub against the front tyre. This is something I’ve encountered when I’ve been using the bigger Jumbo Jammer bag. To remedy it you can wrap the compression straps around the handlebars or alternatively fit a decaleur such as the Restrap Bumper bar.
Capacity
The bag is top opening and has a nice wide aperture to get all your stuff in. I was initially concerned that as I run a GPS that sits in front of the bars on whether that was going to stop me getting into the bag, but it’s not been an issue so far.
With it having a roll top it’s easy to create a little more extra space if needed for extras like waterproofs. The roll top does a great job of keeping the bag water resistant . I’ve used the bag in all weathers and so far it’s kept the contents nice and dry.
In conclusion
Would I recommend the Jammer Bag ? Yes. I know it’s not cheap, but it’s handmade and built to last and ought to viewed as an investment. I find it far easier riding without a rucksack and the Jammer has more than ample capacity for longer day rides.
