Tapered Forks > straight bar frame
Can I put tapered 1 1/8-1.5 rockshox forks into a 1 1/8 straight bar frame?
Am I right in thinking that this can be done with new headset with a 1.5 bottom cup?
need help guys

Depends on the headset size your frame takes. There are a few different sizes for 1-1/8” steer tubes.

can't be done, by straight tube I take it to mean that you have a straight 1 1/8 headtube on the frame, in which case the bottom cup for a tapered fork won't fit in the frame. The inner dimensions of a tapered headtube is 10mm wider at the bottom than the top and it can't be made to fit. The reverse is possible. If you have a tapered headtube and a straight steerer you can buy a devolution bottom race to solve the problem.

Well the only way I know to do this is to buy an adapter. It goes at the bottom of the head tube and is a bugger diameter to accept a tapered fork...this will raise the front of the bike higher because you are essentially putting a spacer between the headtube and the shock. I dont know how raising it slightly will affect the geometry of the bike. Cane Creek EC44 is the adapter...it will only work on some bikes so it still depends on the bike itself and whether it has internal or external bearings. Adds about .5 degree in headtube angle...

The head tube needs to have a minimum internal diameter of 44mm to use a 1.5" tapered steering tube.
