Had a few tubes tear at the valve core last ride.
Need to buy some new tubes for my pack/garage/stock, looking on CRC and found;
Airwave 2.1-2.6 MTB tubes x10 for £26.99 or (no claimed weight)
Airwave 2.1-2.6 DH tubes x10, same price (330g each)
Not knowing much about weighing tubes etc, but figure shedding weight from the rolling stock might be a good idea, is this heavy for a tube?
