Our titanium stem bolt upgrade kits come in a variety of sizes to suit most stems.  Nearly all stem bolts are either M5 (same size as water bottle cage bolts) or M6 (the next size up).  To determine which kit is right for your stem simply extract a bolt from the stem faceplate and from the stem steerer tube ends of your stem.  Determine if these bolts are M5 or M6 and then measure the length of the shaft (ignore the head length).  Then simply select the kit that has the same bolt selection as the one you have measured. 

If you have any questions about stem bolt kits, please contact us at: products@cyclespeed.com.au and we will get back to you with a response within 24 hours.
