26x2.125 Bike Inner Tubes at Poundland. Cheap but they actually seem pretty decent. Thick enough not to puncture, and a pound is a pretty decent price..

Schrader Car type Valve. Roadies need not apply!

11 Comments

Not all Mountain Bike wheels have Schrader Type Valves, mine doesn't and quite a number of other Mountain Bikes with wheel rims designed for Disc Brakes....so it is not just Roadies that can have Presta Valves.

But a good deal for anyone that has Schrader.

Roadies and Mountain Bikes with nice deep V style rims need not apply? Not as catchy though!

All the Mavic rims i've used have come with larger Shrader valve cutouts, if you want presta it's a plastic insert to shim it down, the only presta only compatible rims i've seen have been on older lightweight xc bikes.

I have Mavic 117s on my bikes, and they take a Presta valve.

I have a 117 on the front and a 321 on the rear, and they both came with plastic shims to take them down to presta. A quick google says you can specify them, seems if you spec presta, it's presta only, however if you spec shrader you can shim it to presta as well.

nice find

That makes no sense; an extra few thou of soft butyl offers no extra puncture resistance, it just increases weight.

Erm, most decent Mountain Bikes come with presta valves; schraeder are for cost cutting cheaper bikes...

It sure prevents against pinch punctures however, you can run your tyre at a lower pressure and it is less likely to puncture. Lower pressure = Better grip but Lower pressure needs thicker tubes. Tada

Not always, presta are for high pressure tyres, however at a low pressure the valve has a tendancy to move. A schrader valve is better for those crazy people who like to run tyres 35PSI and below, even better if the schrader valve is a screw type 'ala' schwalbe.

Some just prefer them, especially if you buy a very high end inner tube, you can change the internal valve in a schrader valve.

It is horses for courses really, but schrader type valves are not 'Just' for cheap bikes...

However poundland tubes are very much for cheap bikes If I find any of you have been putting these in your Freeride bike I am coming after you with a large piece of wood

If anyone happens to be looking for these at Meadowhall branch, they're not with all the usual stuff but are at the back of the shop near the toys at the side of an aisle end. Looked to be about a couple of dozen their.

Beware of poundland inner tubes, they are crap! I bought 10 of them and of the 6 I've used so far 5 have developed a split within 2 miles of road use. Also, they will not take a patch - after repairing 3 of them and testing in water to make sure they are airtight, the patch comes off on the first ride! I was using a puncture repair kit also bought in poundland, so possibly they are also crap.
