I have a ‘regular size’ Fumpa based on Dave Rome’s recommendation that I keep in my MTB tool box.
Been waiting so long for the promised new comparison review that I bought a Topump TB2 Pro from Ali Express based on a comparison recommendation from In The Know Cycling for the Flextail Mini (clearly the same pump). It’s been brilliant.
Guage reads identically to the Fumpa’s. It’s much quieter, and super convenient for pre-ride top-ups (so convenient that I actually do them 90% of the time). It comes with a hose but I’ve never used it.
Yet another happy owner of the cycplus AS2 (I have the pro, not the ultra). It has a pressure gauge and an extender hose, and it’s worked well for me. Using it for routine top-offs works really well and reminds me to keep it charged.
I’d say it would be sensible to be somewhat wary of buying any cycle related stuff on Amazon, or indeed purchasing pretty much anything really. Counterfeits are rife on Amazon, AliExpress and eBay.
I’ve bought the As2 pro. I Haven’t had to use it apart from topping up my tubes after letting out some pressure for flying but it did well. I kind of wish I bought the Ultra instead of the pro due to similar stats and a smaller size.
I like my Trek Air Rush very much. I had the Silca version (2 actually), but it didn’t work well on tires with inserts. No such problems with the Trek. Significantly cheaper and quieter too. Would buy again.
This test is now my main focus. It’s hopefully a few weeks out, but it’s a long list of pumps to get through this time around (about 16, excluding those already tested a year ago).
I have had the Fumpa mini in my saddle bag for a year and only had to use it once. I love that it just presses on to the presta valve, but it’s awkwardly sized for the saddle bag and has no gauge. I compared it with the new Silca pump that my friend owns, and still prefer it to the Silca pump, which has a fiddly head and isn’t much more conveniently sized. I just picked up the trek pump and I love it. It’s lighter, better sized for a saddle bag, has a gauge, and a great press on head. Best of all, it was only $135 cad at the local shop. The Trek pump is going on my road/gravel saddle bag and the fumpa is going on my MTB/fat bike.
On Sunday after completing the Olympic Adventure Trail from end to end (east to west), I wanted to add more air in the tires (Fillmore valves) for the return trip on paved road. When I tried to inflate my buddy’s tires, the pump would run for a second or so and then it would stop. I tried that on my tires and the outcome was the same. Essentially the pump would add a bit of air in the tire and when the pressure displayed on the gauge went beyond the set target, it would stop. When I got home, after communicating with my contact at Cycplus, I realized the pump really needs to be pressed quite hard into the valve, unlike the AS2, which I also own.
Question - how well do these electric pumps go with seating a tyre?
I had a tubeless failure mode today I hadn’t previously experienced- hit a pothole and burped a tyre. Went flat and I couldn’t get to reinflate/seat with a hand pump, despite having heaps of sealant. I need a closer inspection but from what I can tell tyre and rim both seem fine. Made me think of whether there are better options for this failure type.
Both inexpensive and one used for gravel/commuter (about 45psi max needed) and one for roadie (about 55psi max needed). Both light and relatively easy to use. I like the one with the gauge more.
Not an easy one to answer as tubeless setups vary so much.
Some of the more efficient inflators will rival a floor pump in terms of airflow and so have a far better chance of seating a tyre than a mini pump. If you can normally inflate your tubeless setup with a regular floor pump then high chance a mini inflator will also work.
Thanks Dave! On closer inspection it appears to be some form of sidewall damage, there is some small hole that air is escaping from and won’t seal. Its quite difficult to see but when I put my finger over it air stops escaping. Electric pump won’t help with that. Will still look into these after the reminder on how hard mini pumps are to inflate with but probably should prioritise a new tyre.
Silca recently shared that their pumps can seat tubeless tires and showed a short video … would love to see some consclusive comparisons if that can be included in the next round.
Seems a bit odd that the Cycplus AS2 Pro has a nearly 7x longer charge time than the Ultra despite ~1.25 times the battery capacity - @Dave_Rome this isn’t a typo for 24 minutes, not 124?
Those dimensions include the head. So yes, a pump like the Flextail Mini is effectively bigger than some of its dimensions suggest.
@Matty This chart colouring is super impressive. Thanks for putting this together. That said, this information is intended for paid members only (and this forum is public). Can I ask you to remove it?
