Our very own range of Titanium products now available at Source BMX. Helping to keep the weight of your bike down to a minimum the Source BMX Titanium Sprocket Bolt is made from high-quality grade 5 titanium with an average 40% weight saving when compared to the steel alternative. The replacement Sprocket Bolt uses a metric thread that will fit most cranks, except for Profile & Odyssey Thunderbolt which use a different thread. When installing these on your bike please use adequate lubrication or anti-seize to prevent corrosion, seizing or cold welding.
