Summer time I carry a cheap 100g plastic 'get me home' Zefal.
Now its winter I'm carrying my 280 gram(with guage) Turbo Morph.
I have had it for 6 so far reliable years and is the close to being a 'track pump for the bike'.
Parts are easily available too so it might just last a lifetime.
Suffice to say I do not have a track pump.
BTW the Mountain Morph is only £21 at
CRC.
Same length I think, but a few grams less. It still claims it can do 160 psi !
