That is a 52cm TT, so a small/medium.  Should be the same size as your bike?  The 21 year old tube exploded the other day, destroying the tyre as well !! 

Most of my bikes use these bb. That's a nice find. Do they have anymore ? What length spindle do they have and how much?

Ok, too expensive for me!! I use mainly Shimano ones and have bought them for rm50 from online when on sale, of course not duraace quality but no problems so far.

Why still use tapered square? If I were given the chance to change the BB, I'll change to a different one that is more superior.

Reason on why touring bikes uses square taper is simple. Square taper is available anywhere , even in small kampong bikeshop or any bike shop for that matter. Touring means, you travel everywhere with your bike, like those 'mat sallehs' you see riding with big panniers on the road. If they were to use hollow tech or octal link etc, the parts are hard to source in small towns. Also those common cone bearings bottom bracket uses square tapered spindles , so although quality is not good, at least it will help you to replace temporarily. They also just started to use disc brakes on touring bikes which many tourers don't want to. They still want to stick to V-brakes as they are also easy to source. And if you use hydraulic disc brake systems, stick with Shimano, Tektro or another brand (can't recall which brand) which uses mineral oil while others still uses dot oil. This is because in emergency, you can fill the reservoir with cooking oil to operate the brake.

u can achieve 50kmh using 55x11, 451 wheel, at cadence around 110rpm..
on flat... assume zero headwind la....

since most foldie and minivelo have problem installing cadence sensor...

many duno their cadence max out at wht value.... ....

  tht is just an example i gave after getting the cadence from bike calculator, not tht i can cycle at tht setting  even can hit oso mebe few seconds oni....
installing cadence sensor on minivelo or folding bike is a problem even for bike with chain stay cos the wheel 20 inch even 451 is too small.

most manufacture like cateye very lazy they do 2 sensor together like ur strada, some got wire linked both sensors, but still too short.

u need to find one tht is totally separated. so far ive come across  few bike computer who does it. polar is one...

or u can use gps for speed n install the cadence sensor to send the crank... sacrificing the speed sensor...
like this tak bleh.....



this still kenot... mebe can...



this can...

If not wrong, you can replace the magnet on the crankarm with flat type neodym magnets such that it sticks at the hole where the pedal is mounted. No need cable tie.

alaaaa...never invite me oso... 

nope..but weekend sumtimes went back to my in law house in Jelapang. always bring my bike together n kayuh alone saturday/sunday morning.

Thanks bro for sharing. Will text u if I'm joining.
