one particular club member of mine mended his pirellis when he
just got it. damn sway that guy. after bout 10 to maybe 13k, he
changed his tyres again. when we inspected his 'mended hole', it
has grown a lot in size. wun one smth like that when i'm going 130
on NSH. a life, 2 or even 3 is worth much more than that.
for the metzler tyres going at $120, if u have doubts, please refer
to singaporebikes.com (aplogies mods, not spamming here).
and ask the mods there. if not, just cut short the chase and visit
Eugene Tan's at Sin Ming, ask him the price for a pair of
metzler (TA200) for SBF members.
just my 2 cents worth
