Q: Which mech hanger fits my bike?

A: Use the mech finder on the left to find the correct mech hanger for your bike.

Q: Does the bolt length include the head ?

A: No,  bolts are measured excluding the head. EXCEPT countersunk where the full length is measured. A drawing showing all the dimensions is included in the gallery for most bolt types.

Q: How do i find the thread pitch of my bolt or axle?

A:  Measure the distance (in mm) between 10 valleys on the thread (10 gaps)   \/\/\/\/\/\/\/\/\/\/  – 10 valleys are shown here.

Be careful to measure 10 valleys NOT the distance between 10 peaks which would be 9 valleys.

Divide the distance by 10 to get the thread pitch.  Eg 12.5mm /10  =  1.25mm

M8 bolts will be 1.0 or 1.25

M10 bolts will be 1.0 , 1.25 or 1.5

M12 bolts will be 1.25 , 1.5  or 1.75

Rear Thru axles will be m12   x 1.0   1.25  1.5 or 1.75

Q: Can you make special bolts?

A: Yes we can. Minimum orders for each size of bolt would be between 50 and 100 pieces. Call or email for more details of prices and lead times.

Q: Can I replace high tensile steel bolts with Titanium ?

A: We do not recommend that Grade 5 Titanium alloy be used in place of high tensile steel fasteners above grade 8.8

If the bolt head is stamped with 10.9 or 12.9 it should not be replaced with Ti without consideration by a qualified professional.

Q: Does titanium corrode ?

A: No. Your bolts are guaranteed for life against corrosion and will stay shiny and beautiful for longer than you.
