Over the years we have been asked for Titanium upgrades. And we have tried , but found that the Titanium upgrades were either very expensive and not affordable or the quality of the titanium was poor. These are precision CNC machined from 6AL/4V Titanium and are less than half the weight of the std. Grade 8 bolts that come in most stems. We sell these as a set of 6 - 4 Faceplate bolts and 2 clamp bolts. And at only 7.25 grams per bolt. Or only 43.5 grams per set. You save a lot of weight for very little money. These Speedline Titanium Stem bolts fit almost all Pro BMX race Stems on the market - Supercross, S&M, Answer, Eleven etc... but be sure to check your stems specs. More sizes available soon.
