Headset standards driving me crazy

[geordanh]

Hey all,

I have not had luck googling and so am turning to you smart people for advice.

I bought a new lynskey cooper frame on ebay ($570!!!! seriously Lynskey?) and thought picking up a headset would be easy. Not so.

It has a tapered headtube, and the inner diameter of the upper is 42mm and the inner diameter of the lower is 52mm. It does not appear that you can press a headset into it, rather the cups appear to be intrinsic to the frame, and there are angled parts where the bearings presumably rest on.

The fork I'm planning to use on it is a parlee disc cross fork which has a tapered steerer going from 1 1/8 to 1 1/4.

It would appear that all of the headsets that are designed to fit the tapered head tube on the frame are meant to accept a 1 1/2 inch lower on the steerer tube, rather than my narrower 1 1/4.

Has anyone encountered this before? Frustrating how many standards there are...

Trying to figure out if there's some kind of crown race increaser I can use to get the race on my fork up to 1 1/2 from 1 1/4 but it doesn't look like anyone makes something like that.

Edit: sorry missed that you said it was designed for integrated also.

These days it is wise to ask the frame maker what forks fit, and maybe even buy the fork from them.


Here's a tool that will help you determine if you can make your fork work:

I think you're going to be better off w/ a new fork. Alower HS bearing to adapt what you have to what you need is going to be a PITA.

1.5" forks are easy to find

If you insist on trying to find something to fit the fork you have, call Cane Creek. They've probably encountered this before and can probably help with sizes, etc

I was unable to find a compatible 1.5" > 1.25" crown race to allow the use of a 1.25" fork in the 1.5" (IS52) headtube of my Lynskey R240.

Methinks you will need to buy a different fork...

1 - you can get a Chris King adapter base plate to take you from 1.5 to 1.25 but as far as I understand you still need the 1.5 lower bearings especially because Lynskey builds cups into all their modern frames.

2 - headset standards are making you crazy because you are trying to fit a square peg in a round hole (or in this case a fork with a smaller steerer into a head tube designed for a larger steerer).

Why not just use Lynskey's newest gravel fork? It fits.

And those frames are really nice. I owned a CooperCX years ago before it went to the tapered HT. Wish I would have kept it. You got a good deal because they are clearing out 2 year old NOS items. Remember, everyone wants the latest and greatest so for the few of us that do not mind last generation we can get really great deals on stuff.

Thanks for the help guys.

I got the parlee fork for a super deal brand new and it has fender mounts and QR which I needed. I will check out that CK base plate but otherwise guess I'm back to the drawing board on a new fork. Didn't realize I needed 1.5 lower, just figured all tapered steerer tubes could be made to fit a tapered ht. ah well

Thanks!

Take a look at this as well..

The lower bearing will be to small for the cup.


It also appears most baseplate adapters are for 1.5 to 1.125 and not 1.5 to 1.25 which is what you need.

Are you sure? Isent it only the inner part of the bearing that is reduced to 1.25 instead of 1.5? Is the outer dia really smaller?

I know you already have a fork, but bikeman has the Kona Project 2 carbon fork for a good price. QR, Fender Mounts, 1.5 tapered. I put one on my brothers Lynskey and it worked out really nicely. Plan to put on on my TwinSix RandoTi before too long as well.

Others are right though. Lynskey does integrated cups, which force you to use specific headsets or steerer forks. Maybe someday Came Creek will offer a 1.25 baseplate for 1.5 bearings..

To the OP, these are what you need

https://www.canecreek.com/store/head...-cover-top-115

https://www.canecreek.com/store/head...is52-bottom-83

You have an integrated tapered headtube. This is slightly different than the integrated headtube. the bearings are Campy/Columbus sized. Slightly larger. Normal is 41.0. the upper is 41.8 but lists as 42mm

If you have a 1 1/4" fork steerer crow, use the conversion one.

The ones I posted are correct from Cane Creek.

Awesome! Thanks! If I was smart I would have just bought that fork from you and done this right the first time.

Thanks for your help.

I don't think that conversion bottom is the right one. If I understand the OP, he needs a bearing that fits a 33 mm crown race diameter and a 52 mm head tube. I couldn't find one on Cane Creek's site. The one you linked is 52 x 30.

Glad that white industries thread was bumped - looks like they sell an IS52/33 which I believe is what I need. Thanks for all your help everyone.
