Half way down Theppasit on the Left Side going toward Sukhumvit just after the juction of the road coming in at an acute angle is a new bike shop selling good mid range big frame Trek, Giant and other name brands.

Don't know if you've been in the one by the Naklua lights ? The chap who runs it ( as opposed to his staff ) speaks good English and will do his best to find a bike that suits you ( Ie big sturdy frame if you like your Chang !! )

Good man.

Numchai is the name of the shop, his name is Pon, yes very nice guy he does a lot for mountain biking in the area, always organizing races and days out and such.

Known him from way back when I used to supply him with titanium frames and Camelbaks from Singapore.

Very important to get the right size frame, I see so many farangs riding 15" and 17" frames which are way too small for them.

so what is the correct rame size for someone who is 6' 2" ?

There are many variables here. Road bike, tourer or MTB? Body proportion and gender play a part as well. Sloping top tube or horizontal top tube? Look at the following on frame sizing - http://sheldonbrown.com/frame-sizing.html

A few general tips - The nose of the saddle should be level with the handlebar stem, if it is higher you will be straining your back and putting too much weight on your arms/wrists and shoulders. The saddle should be horizontal, sloping forward and you will be constantly slipping forward, backwards and it will irritate sensitive areas. You only need the balls of your feet to be in contact with the ground, this will give you a better power stroke without hyper-extending your knees. The seat pillar should not be extended beyond the limit line.

Try out a few different makes for what feels comfortable for you and your pocket.

Talking Mountain Bikes here right? Without seeing your build I should say as a general guide a 19" frame would be OK for serious off road use, but for everyday casual use a 21" would probably be more comfortable, This would allow you more "cockpit" room and allow everything to work better.

When you are sitting on the saddle with your leg extended your heal should just brush the pedal without your hips rolling off horizontal. Your other leg which will be bent at the knee and thigh horizontal to the ground should have the knee bone directly over the pedal spindle. We would often use a line with a weight on it to get the correct vertical. You will NOT be able to touch the ground with even your toes with correct frame and correct saddle height.

This position should give you 50% weight on your butt and 50% weight on your hands, if either is getting sore the saddle can be moved backward or forward by using the two rails under it.

Manufactures usually put a sticker with the frame size on the seat tube. The measurement is usually taken from the crank spindle to the center of the top tube where it meets the down tube. This can differ though depending on the frame construction and amount the top tube is dropped. The other important measurement is from the center of the seat tube at the top straight across to the center of the head tube, this is known as the cockpit and on a 21" frame would typically be 23" This allows your lungs to work, back to stretch out and your knees not hit the handlebars.
