I really hope someone can help me find a solution to this problem because it is driving me mad!!
For some time now, I have been painfully enduring a chronic problem with inner tubes splitting right at the base of the valve shaft. I must have gone through about 10 inner tubes now in the last 100 miles, each and every one on the rear rim, rubber splitting at the same point, at the base of the inner tube valve. I ride a Giant XTC MTB on Mavic XM 317 rims with regular 2.1 tyres and have tried various brands of inner tube.
I use a mini hand pump to inflate and I take EXTREME care whilst doing so nowadays as I am so paranoid over this problem. Tonight I rode home 3 miles and went through TWO inner tubes. At ten quid, this is quickly becoming MORE expensive than using public transport to boot LOL.
I've never come across a problem like this before. I've had bikes all my life and usually can figure out such niggles but this one has me stumped.
I have tried :
Lowering the tyre pressure
Increasing the tyre pressure
Various brands of inner tube
Various hand pumps (not used a track pump but I really don't think this is the issue)
I've padded the inner tube around the area (with old inner tube segments) but still it splits.
Someone....please tell me you know the answer to this one.....
