Found 2nd Jun
Selcof is a basic quality brand from Planet X I think. A bit like Wiggle's Essential range but still pretty decent normally. Even on aliexpress a pair of brakes is about £1 minimum and likely a bit lower quality with a 2 week wait. So 3 pairs of these for £1.98 seems great value. Likely better than those fitted to very low end bikes but inferior to those fitted to higher end bikes. Always worth having some spare pads even if you don't need them now.
