Stem not fitting steerer (Ringle Zooka - Bomber Superfly Z2)

[whyterider]

When I fitted the headset (Chris King Nothreadset) top seal it was very tight and needed some serious coaxing to get it down the steerer which I found a bit strange, but eventually I got it into position.

Today's dilemma is that my lovely Ringle Zooka has arrived and will not fit onto the steerer at all, it is definitely 1 1/8th as it fits another pair of forks of that size :shock:

Has anyone encountered this problem with Bomber's before, I am however guessing there may not be a solution :?:

Any help would be greatly appreciated.

I had this issue last week, not with a Ringle stem though, just a cheapy one, it went straight on with no messing on a Manitou steerer but when I changed forks for Bombers it took quite a heavy hand to get it on :?

Thanks Bob, so it's not just my pair!

Check to see if the radius of the steerer is the same all the way around. Is there a flat spot anywhere?

The CK upper race can tend to be a bit tight on some steerers but it will go on :?
a problem ive found on fitting stems is that if there is so much of a small burr on the lip it prevents a stem from going on
Give the top of the steerer a rub with a file to clean off anything that might be impeding it.
Spreading the slot on the stem will also help

Thanks sancho and dyna-ti, the steerer is even all round and none of the components have burrs.

Spreading the slot on the stem will also help

Unfortunately by the nature of the Ringle Zooka it does not have a slot, it is solid all round. I may try removing the paint from the face which meets the steerer as this may give the space it needs.

Alternatively I may just stick with the Ritchey WCS stem which was temporary on my current project but looks okay....the Zooka could be an excuse to start another build :roll:

I had exactly the same problem, I gave up in the end and used a different stem :?

It would have gone on with a bit of force but I didn't chance it all the other stems I had in the house fitted so it was the Ringle stem not the steerer in my case.
