Anyone know what the diameter and pitch of the thread is on the front axle?

umm,, im going to have a guess as i use R1 front stems.. Its a metric fine thread,.. soo.. 28x1.5 at a guess. If i had a sample i could tell you easy.

Any specific reason you want to know ? Ride to some local machinist workshop, take the front nut off, show them and say "what thread is that ?" and they can measure it real quick with a set of "thread-gauges". Else you can go to your local trade shop and buy some for like $5. Always handy to have around.


They look like this and you find the one which fits on the thread. They work internally on nuts too. Find one which lines up perfectly and it tells you your thread pitch.. Then just measure the diameter of the axle.. So if its 28mm on the axle, and the 1.5 gauges fits.. guess what..
