the max PSI stated on the tire is only for the tire itself right? the tube inside can go however high it can? if i change the tire that can withstand 80PSI, the tube can handle to?

theoretically tube no pressure one... the pressure is actually between the tube wall and the tire inner wall. so tube doesnt matter

GoPro Hero Session 4 now selling at $300 or $350 I think. The speedometer thing can use free Garmin VIRB Edit software to add overlay with your .gpx or .fit files from a Garmin Edge, for example.

just ride hard, can become faster and faster. it helps that I had 2 coaches who taught me to ride better.

my coach always tell me you wanna ride fast have to keep riding at that speed, if you ride at 40kph you always think those riding at 50kph is fast and so on.

Just now cycled at Seletar loop 2 rounds with my 14kg brompton.

Can roll at about 26-29kmh.. drafted behind some road bikes and chiong at 34kmh before the cyclist stopped one side and shot me a dirty look. :s13:

Wah, that stem sounds way too long. If the pain comes in after 10 min, means the bike fit (or lack of) is wrong liao. You can try looking for a loan 110mm or 100mm stem, see if it feels better then buy one.

If not, try dropping your stem down by 10 or maybe even 20mm on the steerer tube.

I realise I was not really sitting on my butt bone, shifted my saddle forward a little to have more weight on my butt and will see if my lower back still hurts. Otherwise, like u said, might have to change stem le.

He tot u tailgating n wanted to overtake. He tot he too slow so he rode faster and maybe want to shake you off. But then u keep chasing, make him as a roadbiker malu. Then he stopped, you also stopped. He realised he had been made use of for drafting. Double combo malu. Yet u not paying him any tips, lagi sian. Next day onwards u will never see him there anymore. See la, u should make fren with him.
