hi all, i have a question i'm hoping you can help me on.

when i got my addict R1 frameset, it came with Ritchey WCS Logic Zero Press-Fit Headset (not assembled).

when i tried to install the press-fit onto the frame, it seemed too tight and wouldn't go in right.

so, not sure if i can use some fine sand paper to widen it so the press fit will go in? or should i try to press it in? (which i don't think should be the right answer in case it'll crack the carbon?)

Image

any suggestions?

also, on my fork, shouldn't there be a crown race installed onto the fork? when i had my alum CF fork, there was one that was installed on.

can't help on the specifics of your frame/fork, but headsets and crown races can take a lot of force to fit/remove, if you do not have the correct tools it can be a struggle or risky to try it, you want to keep forces on-axis and evenly applied

unless someone else can give you a definitive answer, i'd contact scott direct and ask them if the frame or forks need any prep before fitting the headset

if the crown race is missing, it looks like you can get them separately, for instance...

not being familiar with this headset I looked at the Ritchey site. very disappointing level of information there is no help.

my gut feel is that if you should be able to push that in by hand, I too would not want to be hammering on it.

normally the fork would need a "crown race" but since I'm not familiar with the Ritchey design, maybe they do it differently - the tech docs are no help.

if no one here helps there's a Ritchey rep string over on the RBR site. try there. http://forums.roadbikereview.com/ritchey/ritchey-rep-here-answer-all-your-questions-210005.html

Don't modify the frames or the cups. It's best to use a headset / BB bearing press as cups need to go in square.
The fit is tight but they'll go in easily with the right tool. Your LBS will have one.

You should have got a crown race with the headset. Again easy to fit with the right tool.

yea i noticed scott's contact form wasn't much help. i had emailed them before and never got a response. :( but thanks for the RBR site.. i'll ask them and see if there's some answer.

***********
thanks to all that responded. at this point, i think it's better for me to buy a complete set than to tool around with these parts. which headset would you recommend that would have all the parts included and very lightweight? :)

BTW a Ritchey crown race is commonly available as a spare part.

Hi

I have had a scott addict sl with the same headset .

A tip is put the shells in the freezer for about a day . ( tip from a dutch forum )
You stil have to use some pressure but not as much .Normally its not possible to push them in by hand and you will have to use a special tool ?
Instead of that special tool you can also use a threaded rot with some big washers and nuts .Its cheaper than the tool and works just as fine .


And the crown race . I made a cut in them on one side and they went on easy . And i never had a problem with them .

Thanks for the tip. Trisports didn't send me the crown race.. Boo!!!

Anyway I went to sports basement and bought a crown race and they installed it for me and the press fit onto the frame too. All I paid was $15.. Woohoo. Now the rest I can start putting on tonight after I cut my fork.

I would not do it this way.

Press fit is the best way.

Say goodbye to any hope of warranty help if you cut a slot in your crown race.

If you're keen on doing this stuff at home, it's worth your money to buy the correct tools. An Addict is no place for jury-rigging.

It's pretty easy to install a crown race. They should be a tight interference fit. You can gently sand your fork steerer so that the race falls easily to within about 10 or 12 mm and then drive/press it home from there.
All you need is a piece of PVC pipe (~40 or 50 mm diameter. I dont remember). The pipe just has to be a bit longer than the steerer.
Slip it over the steerer, tip it over and tap it on the floor to drive the race home.

I think you should know that the Tune headsets come with the slot already cut into the crown race.

You can press the crown race on with your headset if you have enough spacers. I've done this numerous times now on oversized tapered forks because my old 1 1/8th crown race tool 'pipe' no longer fits. It works (in my opinion) far, far better than hitting a pipe with a hammer to seat it. If you have enough headset spacers you can do it with an uncut fork, if you've already cut the fork, even easier :thumbup:
