1" fork conversion to 1 1/8"(3 posts)

1" fork conversion to 1 1/8"pessot
Apr 7, 2003 7:51 PM
Can I take a fork with a 1" steerer and convert it to use in a 1 1/8" head tube? I imagine this could be done with some sort of sleeve ( 1/16" thickness ) that could slide
over the steerer tube.

I have a 1" fork I'd like to use with a new frame.
Is this possible?

... QBP makes shims (your LBS can order them) for using 1" headsets in 1 1/8" headtubes... Also, Chris King makes a "devolution" conversion kit... allowing a 1" steerer to be run in their 1 1/8" headsets... I've used both methods successfully (other headset makers may have similar conversion kits)

Be the bike.
QBP has a part for that...retro

QBP (your bike shop can order from them) makes a part for that--I had to use one to run a 1 1/8 fork in my 1 1/4-tube Cannondale. It's a couple of little alloy rings that press into the head tube, HUGELY overpriced--like $40 for an ounce of aluminum. It's called a headset reducer, and the part No. on mine (yours would be different, but they're probably right next to each other in the catalog) is HD9900, 37mm to 34mm.
