4 Seasons are a good bet yep. Wouldn't see a much of an issue with GP4000 SIIs either for winter but probably a little less puncture resistant.
My sodding grub screw for the brake pad has rounded out![]()
Cheers, will just see what I can the best deal on. They'll probably be far superior to these ling longs anyway.
For the grub screw, have you tried a slightly bigger Alan key, maybe an imperial one and jamming it in there with enough force to just get it out?
