which tubes for deep section rims?

paul_mck

Guys I have some 60mm deep section rims and am stuck for tubes. I prefer to have a long enough valve (80mm) rather than use valve extenders but can only find the conti race 80mm tubes. And they are rubbish. Have had to bin 2 over the weekend due to holes just below the valve. One was in the tyre for a couple of months and punctured last week, and the other was holed on insertion. And at £8 a pop they arent cheap! (£5 on offer at wiggle atm though but still).

Can anyone recommend a good reliable tube with an 80mm valve?

Cheers.

Just use a Lezyne valve extenders. They work great and have a little screwy bit on the end you can use to open and close the valves.

Planet X do 80mm inners: http://www.planet-x-bikes.co.uk/i/q/TUPX700LWR/planet_x_700c_lightweight_road_inner_tube

£2.99 a go - not sure how good/light etc they are, but worth it for the cash?

I'm contemplating the same for my 50mm rims. Except I fancy using latex tubes. Does anyone know of any 80mm latex tubes? I don't want to use valve extenders.

in my experience conti tubes are fine

barring a bad batch, if they're puncturing in the same place i'd be inspecting the rim/tape to find the cause

I was about to say the same thing. Never had issues with conti tube failing by themselves, there is always a reason and it normally easily found.

2 diff bikes guys

bike 1 (commuter) - tube been in tyre for about 3-4 months then took a slow puncture
bike 2 (good bike) - just got some second hand wheels and fitted a new tyre and tube to the rear, tyre went flat

I reckon I nicked the second one fitting the tyre and the first one who knows but the strange thing was they both failed in the same place just below the valve about a 1/4 of the way around the tube.
