Classic and Quality

The Good:

Durable. All of the sizes ever needed. Classic stem for a classic build.

The Bad:

Lack of colour options. 3mm bolt heads

Overall Review:

Pretty much the go to stem for so many builds. Not super bling but a name synonymous for quality.

The only thing I do not really like is 3mm hex headed bolts to clamp.
