The only stem I use

Every new bike I get is automatically upgraded to the I9 stem. Got and finish is amazing and complements the bike perfectly.

Bronze
- Familiarity:
- I returned this product before using it
I ordered the Bronze 50mm. Color is way off. Returned the first one thinking it was packaged wrong. Recieved the replacement and its the same gold.

Love the I9 Stems!
- Familiarity:
- I've put it through the wringer
- Size Bought:
- 50mm -318 size
I got a new bike that needed a 50mm stem and this Orange colored I9 - 318 stem was on sale. I would of bought it off sale anyway. They just fit so well, look so good and have the best polished edges and thick anodized finish around! Light too! I've got a 40mm on another bike and it's bullet proof after 2 years of hard riding.

Top notch American craftsmanship ...
- Familiarity:
- I've used it several times
It's Industry Nine, so expect something strong, well engineered and beautiful. Granted, it's a bit pricey and there are other cheaper stems that will just just as good a job, but I always choose to support small American businesses whenever I can. In a way, this stem is fancy bike bling, but it's also of the highest quality and will probably last you a lifetime.
