New Stem for Winter Bike

by PNWRoadRider@Seattle on January 4, 2020

Product: Dimension Threadless Road Stem: 90mm; 107 Degree; Black; 1-1/8"; 31.8

Ownership: a month

Tech Knowledge: high

Pros

Solid, well made product with good quality bolts. Fairly priced. It's not fancy, but adjusts my position to exactly replicate that from my other bike, so thought it well worth the cost. I believe I was right. Looks good in the rain on my cross bike.

Cons

No functional cons. It's not fancy looking is perhaps a con for some.

Other Thoughts

I like to buy on line, because it's very efficient and I have a huge product selection to choose from. I always start at Modern Bike, because they have always been on time with the product ordered and have never had a problem with their service. I've been shopping there since 2012.

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.
