I need some help on repairing my bike, I have a GT Arrowhead thats needs a bit of TLC.
The gear part by the pedals has a couple of teeth missing which causes the gears to slip when riding, which makes the chain fall off - The casette i think its called - so is going to need replacing -
I also need to new tyres as the others are starting to get worn. I did have Maxis 190's Wormdrives on there but they were on when i bought it. They are 26 x 1.90 - Can i jusy replace it with another 26" wheel or does it have to be a 1.90 - im presuming its thet similar measurements to car tyres-
Could anybody recommend me a tyre and the cheapest place to buy them please!
