Hi, I'm looking to buy a headset press to fit a reducer and then 1 1/8 headset and normal forks to a F800. Will a Cyclus press do the job or do i need to buy a Park?

dunno offhand, but just measured mine (crap placcy verniers I'm afraid) and the step diameters are:

~26.4mm
~29.9mm
~33.7mm
~37.9mm

HTH

cheers Jond most helpful and the right size – would you recommend it?

Ah, good 🙂

Yeah, it's a pretty decent tool, with a simple ball-bearing race at one end to make the press action smooth – I've used it to fit an FSA, and a Hope.

(It wasn't the fault of the press, but the Hope was a bit of a PITA. I have the press blanks for both their headset and their xc hubs, but gawd knows what headset tool they're supposed to fit – I had to do one end at a time, very carefully, tho' once the cups were most of the way in the rest was fine.)
