I've got one of these. http://www.evanscycles.com/products/spe ... 60#reviews It was very expensive but has worked well until now. The hose has broken from the base of the pump and also from the "Smarthead" following my fiddling. The main part of the pump functions fine after I recently greased/serviced it and the "Smarthead" is also still fine. I just need to connect the two bits securely. Anyone else got one and had the same thing happen? Are spares available? If not, any way of fixing it with standard hose bits and connectors of any sort or bits from other manufacturers?
