Ok thick question im sure but I pumped my tyres up to around 75psi and i wasnt even jumping or anything and the tube let go - it had a big 3mm slit dead centre on the inside of the tube. what a pain so got a new tube, again i was just out riding no tricks and pop again......not the same place but inside again.
so iv check the rim tape and the rim for sign of something sharp but nothing, and it aint like im running high pressure - i am 13 stone mind but like i said i wasnt jumping or anything?
thing is the rim tape aint very wide and sometimes the rim holes show which i guess that may cause it?
any thoughts? as i cant afford to keep going through tubes like this and its stopping me riding right now.....
