I have taken my BB out of my MK1 Dialled Holeshot to buy a new one, i took a pic of it and thought i would look at it at work and by a new one. But Shimano square taper BB and where it normally says the width it just says D-H, Any ideas on the BB width i need or what the D-H stands for?
You need to measure the shell on the frame and it will probably be 73 mm.
You need to measure the width of the old axle...typically 113 or 118mm or similar.
Assuming the cranks are Shimano, it will need to be a JIS (NOT ISO) square taper if not a shimano replacement.
CRC and Merlin do cheap Shimano UN55 replacements.
D-H does not mean anything to me.

I will do that when i get home but wanted to order it today at work 🙁You need to measure the shell on the frame and it will probably be 73 mm.

I will be replacing it with ISIS BB and cranks.
Then your new ISIS BB needs to fit the frame.
Some come as 68-73 so fit both, albeit with a spacer on the drive side when in a 68mm shell.
If you already have them, no problem.
If not, check whether you need 113 or 118mm axle for the new ISIS cranks.

the Shimano one was 68mm, Will measure it when i get home. Cheers Paul
