After years of good use, the pump has lost pressure and a look shows the O-ring seal has gone on the plunger. I’ve tried other o rings I have but can’t get a good seal. Where sells spares for these? Or just give up and get a new one? I have seen complete new ones for £30 ish so maybe that’s the better option. Cheers

sjs have pretty much everything

Topeak dealers carry a spare parts/repair kit

How good a joe blow is it? I didn’t bother repairing my Sport when it blew, just because it wasn’t a very good pump.

My LBS just has a box of all the spares, costs pence to revive, I’d do it.

thanks all, will try sjs or lbs

I upgraded the head unit on mine when it went and it’s been far better. Much more secure clamp on the valve and seems to work better on tubeless.
