What sort of pump do people carry on road bikes theses days?

I'm finally retiring my old road bike, which has a neat frame-fitting pump, but the new bike has a
"compact frame" with sloping top-tube.

On my mountain bike I carry a short pump in a mounting low on the seat tube, but this would look a
bit messy on an elegant road bike

I agree, but my compact frame is too small for a frame pump. I've got a Blackburn Airstick AS-1
mounted on the bottle cage. You could put an even smaller pump in your jersey pocket.

I find my road bike looks odd _without_ an HPX under the top tube!

Hi.

Having used many and various pumps over a good few years the 'SPECIALIZED Airforce4' that I have now
has been the best so far and mounted on the bottle cage looks quite spiffy on my current road bike.

Cheers

How long is it, and how many psi can you get from it? Other pumps might be lighter and look better
but no mini pump can compete with the HPX when it comes to high pressure :) (Just not physically
possible).

Too right; LENGTH IS STRENGTH!

I have a largish supply of fairly useless little pumps, which I'm quite happy to donate to anyone
who is willing to send me an email first and to pop round to collect.

It's about 10" long & rated up to 160psi, I have no trouble getting upto 110-120psi .

Yep its also easy to inflate tyres to 110-120psi with cheap SKS or Zefal (SPS?) framefit pumps
costing 3 or 4 quid a 1/4 of the price of an HPX, much lighter than a HPX too.

The only downside of the cheap pumps is they can explode if you treat them without respect.

I can't agree. I've still got a Zefal SP size 4 and anything much beyond 95psi with it (and every
other cheap pump I've tried) is extremely hard work. The HPX is far superior because it has a
narrower barrel, spring lock-out feature and a better valve connection system. I like to save weight
on my bike so there's no way I'd carry this big heavy ugly expensive thing if it wasn't so damn good
at inflating my 130psi tyres. It's also just simply nicer to use with _all_ tyres.

In a small pack under the saddle I carry 1 set of plastic tyre levers, two spare tubes, 1 pack of
self adhesive patches, 1 CO2 inflator, 2 spare CO2 cartridges, 1 chain link extractor, and 1 20
quid note.

The inflator hasn't let me down yet but the obvious risk is that each cartridge is a one-shot deal,
so if you tear a tube or have a fiddly puncture that takes several goes to get right you could run
out of charges.

Depends if you have any upper body strength or not. I have the proverbial pipe-cleaner arms and
can't get 120PSI out of a cheap Zefal for love nor money. I can get 90, which gets me home but isn't
ideal for 23mm tires.

Just to confuse the issue I have a HPX but normally use a blackburn double action mini-pump (a very
good quality one) out of which I can get 110PSI, which does fine (I normally only pump to 115PSI
with the track pump anyway)

Upper body strength is an issue, but I'm no weight lifter. I think technique is important:

I wear leather palmed track mitts (the frame fitt moulding is painful)

Brace the valve end of the pump against something solid (to push against)

Press the pump up into the valve (so the weight of the bike holds the valve in the pump).

Lean into to pump so the final part of the push comes off your shoulder.

You only need a momentary max force on the pump of ~ 30 kg

Obviously a track pump is the sensible thing at home. But for the 1 or 2 % of rides I actually need
to fix a puncture, a cheap pump is fine.

This can be very tricky - verges and hedges don't supply the necessary.

Personally I think that getting back on the road quikcly and with less fuss is worth 20 quid.

I know that the day I leave the pump at home will be the day I get a puncture, so as long as I have
a reasonable pump I wont get a puncture. Decent tyres help, too.

The zefal SP is cheap, lightweight and snugly frame mounting. Its quite comfortable to hold at the
valve end, too. (as long as you dont have too many spokes)

I have carried a pump whenever Ive been out on a bike and consequently havent had a puncture since
september. The pumps have been used to pump up plenty of other peoples tyres though!
