About Us

Welcome to Certified Slammed, the official webstore of SlamThatStem.com

Yes, we have a webstore. Soon there will be some new products on it, so watch out, yo.

Right now we sell headset bearing covers. They are manufactured in Michigan, USA. They will make your handlebars lower (potentially even slammed). This is great if...
1) you want to get your fit dialed in lower 
2) you want to be more aero 
3) you want to win bike races
4) you want to attract attention to yourself among your peers
5) you want your bike featured on slamthatstem.com (not a sure thing)
