It's the measurement of the seat tube. Starting from the center of the bottom bracket to either 1. the center of the top tube 2. top of the top tube or 3. top of the seat tube. Because of this variation, it's sometimes hard to compare sizes exactly. This is one reason (of several) advice is given to try the bikes in person for fit. Mountain bike frames tend to be measured in inches, road bikes in cm. Kids bikes are mostly measure by wheel size only.

Depends on the bike manufacturer but most measure from the top tube to the bottom of the frame. Usually it's measured in the metric system. A 15" frame would be small and a 21" frame would be for a large person.

The broken area is asserted as the dropout, and yeah, this is replaceable with out difficulty. It occurs rather in many situations, and in certainty, some severe-abuse mountain motorbike frames are designed with replaceable dropouts so as which you do not could bypass during the difficulty of restore and welding (on frames the place this is risk-free/obtainable to realize this). Any framebuilder can put in new dropouts for you...they might propose doing the two one among them instead of purely one, observing the region and availability of an same area. it would additionally be a good time to get any upload-ons which you quite want (pump peg, chain hanger, water bottle braze-ons, shifter/derailleur mounts, and so on). you're able to snag a used physique for greater decrease priced than what the restore will fee, yet you could actual have it fastened in case you want to. Ask around interior sight motorbike shops to work out if there's a framebuilder on your section, or seek the internet for them. There are plenty accessible, some flashy and renowned, some obscure and unknown yet nonetheless relatively experienced. good success! save that previous Dawes going! :o)

It refers to the size. M R has it right, except that on most double suspension bikes the frames come as S, M, L, XL because the designs are not that standard.
