Hi,

My Big Honzo is showing signs of needing new headset bearings. I'd like to get the bearings ready so I can just swap them over without having to wait for bearings to arrive.

Does anyone know what sizes they are? I've trawled the interweb and come up with precisely nothing so does anyone have any info on sizes etc?

I fear they will be cheap caged bearings, you may as well just order a posher headset, headtube size should be printed on the back of the seat tube

Thanks Sound advice. But I can't see headtube size on the seat tube sticker. As with the above image the bearing size is there but not the tube size. I assume the headset you show will fit straight in. (Excuse my ignorance - I'm a converted roadie so am not up to speed with this mtb gear!!!)

The old one will need knocked out and a new one pressed in. You tube will be your friend.

A big punch or flat screwdriver and a hammer and a good bit of care should knock the old headset out or buy the headset extractor tool.

To press the new one in it'd either be a lump of wood and a hammer and a lot of care to make sure it goes in straight or a bearing press (bearing pro tools, bsc tools are good and cost effective)

Or if you don't like spannering yourself, drop by a LBS.

s with the above image the bearing size is there but not the tube size.

the numbers are actually the internal dms of the headtube

44/56mm semi integrated headset is pretty standard for Konas ( I have a Honzo and a Process)

Thanks again. I've knocked out and replaced headsets on road bikes - even have my own Heath Robinson press so that won't be a problem. Even have the tool for knocking bearings out. So long as I get the right ones I think I'll be OK. I've ordered one of the FSA above^^^ and DPD are supposedly bringing it tomorrow.
