Headset converters (size)

Postby mattsccm » 22 Nov 2020, 1:51pm

Anyone used this sort of thing? https://www.ebay.co.uk/itm/1pcs-Bike-Ta ... SwrV1dhJSh
I want to put a straight steering tube, 1 1/8" fork into a frame made for a tapered fork. Got spares of both but not the other halves. :roll:
I had assumed that I would be looking at a complete headset but these things look as if they just drop on the fork and I then use the tapered headset.
Any experiences or thoughts?

I once bought a used bike with such a thing fitted and it seemed to work OK. Not sure whether it was original to the bike or a budget repair to a bike using a less expensive fork; IIRC it was the early days of tapered steerers and forks with the correct steerer would have been fiercely expensive.

I've not used one, but Cane Creek sell the crown race baseplates for their 40 Series headsets separately, including one sized for using a 1 1/8" steerer in a 1 1/2" lower headset cup: https://www.sjscycles.co.uk/headsets/3826-1-inch-cane-creek-crown-race-for-40-series-headsets/..

I don't know if it makes any difference compared with the split race linked to on Ebay, but the Cane Creek 40 Series baseplates are not split (they have a seal).

For a few quid I suppose its worth a punt.
What has to be right? I guess fit to your forks and your bearing unit.
If it doesn't work Hope also do a bottom race which almost certainly will work https://www.hopetech.com/_repository/1/documents/Hope-Lower-Headset-Compatibility-Chart.pdf and although I can't find it on their website, Spa also do one (probably cheaper than Hope) so that they can fit forks with 1 1/8" straight steerer into the Elan which is designed originally for tapered carbon steerer.
