▼HELP SECTION

Extension Length (ctc) - this is measured from the centre of the handlebar clamp to the centre of the shaft, to the point where the stem bolt passes through. We always take this measurement in a straight line through middle of the extension, not along the top.

Quill Size - the most common size for classic and vintage road bikes is 1", this should be the same as the outside diameter of your fork's steerer column. Oversized steerers found on mountain bikes and later road bikes will be either 1 1/8" or 1 1/4".

Steerer Size (ID) - this is the most important measurement when checking the stem fits your bike. This should match the measurement of the inside of your fork's steerer column, where the stem will be inserted. The standard size for road quill stems was 22.2 mm, or 22.0 mm in France until the 1980s.

Total Shaft Height - measured from the top where the expander bolt head sits, to the bottom of the stem's shaft. To give you an idea of how high the stem can be set, there should be an absolute minimum of 50 mm inserted into the fork steerer, although most stems come with a 'minimum insertion line' to help with this.

Clamp Size - this should match the outside diameter of your handlebars and should be as close as possible to ensure a good and safe fit.
