Muc-Off BAM! Inflate & Repair

BAM! Inflate & Repair is Muc-Off's solution to fixing punctures quickly at the side of the road. A tubeless solution for the tubed, if you like. It works well in most situations and gets plenty of air into your tyre too, although you need to make sure the nozzle is on the valve tightly before you let it rip. It's a pricey solution though.

For most of us, getting a puncture out on a ride isn't a massive deal, especially if you are running tubeless – and if you are using a tube it's not that much of a pain to swap things over or fix it with a patch at the roadside.

However, if you're a commuter with time restraints, a racer, or you're riding on tubulars then BAM! (Bottled Air Magic) could be a bit of a lifesaver.

In the 125ml aerosol can is a mixture of latex foam and compressed air, which, when you push the pink cap of the tin against your valve (Presta or Schrader), will be injected into your tube/tyre. It contains no ammonia so should be compatible with most tubeless sealants.

First, you need to inspect the tyre and remove what caused the puncture in the first place, which can be a little tricky if it's gone right through the tyre tread, but if you often inspect your tyres before you ride then new cuts and holes are often easy to spot.

If I do puncture it tends to be a thorn or piece of glass and I can normally just pull out the offending item.

With that done, all you need to do is stop the wheel with the valve in the 12 o'clock position, give the BAM! a good shake, and then offer it up to the valve.

You need to make sure the tin is pushed firmly onto the valve and keep it straight – if you don't, you're going to end up looking like you've been to a foam party. The stuff comes out pretty lively and if it escapes it goes everywhere!

If it all goes smoothly, the tyre inflates quickly (I achieved 90psi easily in a 25mm tyre) and I had no issues with the puncture holes sealing.

Muc-Off says that it'll work on holes up to 3-4mm and I'll go along with that, although the BAM! did struggle when the pressures got higher – at road pressures I'd say the Muc-Off works best on holes between 1mm and 2mm. The lower pressures of about 35-40psi on gravel tyres were no problem.

Unlike some, such as Zefal Repair Spray for one, BAM! is a permanent solution so you don't need to get home and replace or repair the tube. The punctured tube I used has been running fine for over three weeks with no major loss of pressure other than the norm.

I still ride tubulars on one of my bikes, and with the kind of get-out-of-jail solution the Muc-Off provides for most small punctures I have invested in a can to keep in my rucksack, even though it is quite pricey at £14.99.

The Zefal I mentiond above is just £5.99 for 100ml. It doesn't provide as much inflation as the Muc-Off, though, and as I said, it's only designed as a get-you-home solution.

BAM! is the same price as the GUP Kwiki Sealant and Inflator, which is also 125ml and sounds to be a very similar type of solution.

Conclusion

On the whole, I reckon BAM! is an expensive way of fixing a puncture but if you are running short on time or are using tubulars then it's worth the investment.

Verdict

Pricey way to fix a puncture but works well and offers peace of mind for tubular users
