Hand pumps..and Co2 cartridges.

[rocks]

As I am planning to do some travelling on the bike, so been looking at the little extra's you need to pack to ensure a trouble free ride..

been looking at getting a small compact hand pump incase of punctures.. i have seen the ones on the Touratech website and they look nice, but are they any good.. anyone used one in anger??

Also looking at a small tool kit.. and spare puncture repair kit.. where is the cheapest place to get one and, the little Co2 cannisters?

.. and spare puncture repair kit.. where is the cheapest place to get one

Hein Gericke do the complete REMA (same as BWM) kit for £12.99.

I've asked the question about spare cartridges recently but not had any answers so far.. looks like you have to get the complete kit.

Try a decent bike shop............the same co2 cylinders are used for mountain bikes.........they used to be sold seperately in Halfords but i haven't checked for years.

Two types..

I see there are two types of the cartridges.. ones with screw threads and ones without..

Have checked on the hand pump prices.. seems TT are actually not that exspencive for a change..

Halfords

For 8.99 you will get a electric pump from Halfords. Comes in a nice plastic shroud. Unscrew that and put your tool kit pump and repair kit in the bag supplied for original pump.

There is a small hand pump from the USA called second wind. It virtually folds in half and works as a standard air pump for pushbikes. It also pumps up motorcycle tyres but it takes about 25 pumps to add 1 psi I know as I have one.

The second wind part of the name comes from the fact that this pump can be arranged to use the C02 canisters as well. There are two main types of canisters screw threaded ones and screwless. The second wind pupm takes both versions and can also handle the very large C02 canisters that are used in commercial applications. The large ones have about the same as 3 normal canisters.

If you do wish to use a C02 canister it would pay you to carry a swivelling 90º adaptor for your tyre valve. The reason is that to get the most useable of the C02 out, your canister has to be vertical. This is because when the pressure is released as you either puncture the lid or open a valve, the C02 boils off and becomes a gas. Using the 90º adaptor enables you to keep the canister vertical no matter what position your valve is at.

I run an early model second wind and it fits inside my Touratech tank bag.

If I was on the market today I would seriously think of the Touratech pump, it is a very good double action pump and reasonably priced. Other than that I would opt for the current second wind

If you are able to get to this site you'll seea second wind pump fully extended, it folds up to less than half of that length, about 200mm or 8" long.

Hand Pump

You have a GS with external power socket, get an electric one, use the technology at your disposal.

Where's the kit that originally came with your bike?



If you want a small electric pump, look no further than here (genuine offer!)

If you wish to go the electric pump route then you need an electric pump with balls.

I know that most of the pumps available will pump to incredible pressures, but, and there is always a but. How long will it last before it overheats and you are stuffed with a flat tyre that may or may not be seated correctly after taking the tyre off the rim in the sticks.

Most of the real cheapies are just that, cheap. There is nothing wrong with them but they do have a limited life before the major components, like the piston collapse. I have seen quite a few really cheap units and they just don't cut the cake for seating 1100 or later GS wheels.

I myself have what I call a cheapish electric pump for re-seating the bead in the bush and the size of the piston does count as to whether or not it'll be able to pump air quick enough (allowing for leakage) to force the bead over the safety seat before the whole thing just overheats and stops gasping for air.

Pull the plastic cover off and check out the size of the piston. From my experience you need something like a 30mm diameter piston to pump air quick enough. The really cheap ones have about a 15mm piston and the real hero pumps run a piston something like 40 - 45mm in diameter.

My own pump has a piston about 35mm in diameter and I can tell you that it pumped up a friends 21" front wheel from dead flat to 35psi in 45 seconds. It takes me 1'55" to get 28 psi (2 bar) from flat in the rear of my own tyre. The tyre was seated on the rim just flat, this was a test run.
