StarStarStarStarStar Updated Older Bike

by Ernie P. of Seattle, WA
Product: Sunlite TCO Piston 2-Bolt Clamp
Ownership: a few months
Tech Knowledge: somewhat high


I needed to update my 90’s era bike to fit my aging body: shorten the distance between seat and handlebars and raise the bars a couple of inches. Needed a quill stem. This worked beautifully! My old bike is now as comfortable as my newer ones. Well made, nice finish.



StarStarStarStarStar change stem to change road bike seating position

by John H.
Product: Sunlite TCO Piston 2-Bolt Clamp
Ownership: a month
Tech Knowledge: somewhat high


Suitable for vintage frames with quill stems.
Allows a more upright/less aggressive seating position.
Ideal solution for shortening rider's reach while retaining long-reach randonneur-type handlebar.
Does not change my bike's handling characteristics, even for out of saddle climb or sprint.
Two-bolt design allows changing out stem without stripping off one of the brake levers and associated handlebar tape.


The absence of the typical stem reach gives the bike a somewhat odd appearance.
This particular stem appears to be too long for any frame smaller than 56/57 cm unless the buyer wants an abnormally upright riding position for road bikes.

Bar clamp diameter is the diamater of the handlebar.

Stem length is measured from the center of one clamp to the center of the other clamp. This measurement is sometimes known as the reach or extension.

S.H.I.S clamp diameter is the steerer tube diameter.

Stem angles are measured perpendicular to the clamp. For example, a 90 degree stem is straight. Sometimes, this may also be refered to as a 0 degree stem. If two measurements are listed, the stem can be flipped for angling up or down.
