Headset problems

Graydawg

Hi all, I just bought a 1 1/8 headset from my lbs and went to install the cups in to my boardman 2013 Frame however it would appear that they aren't fitting (pressed in) as the head tube seems to flare out slightly? When I bolt it all up it appears to be tight and ok but am worried as soon as any lateral force is applied it's going to come loose as the cups aren't pressed in but just sitting there.. Is this ok or is it the wrong one?

Basically if I remove the bolt from the star nut the cups are loose...

Please help, I am stressed out that the lbs has sold me the wrong one... :S

Ok I have googled it and I could use "headset reducer cups" to solve the problem???

Sounds like you have bought the wrong type of headset or the wrong size.

Graydawg

Thought so. Back to the shop tomorrow then!

And take the frame with you.

Good shout. Just took it off the frame and will take it back.

Here's some measurements of the old cups using my digital calipers..
Old cup external diameter of bit that sits inside the frame...







External diameter, (not that it really matters I don't think!!)





Does these pics make any sense?

Thanks mate

So I'm guessing actually this is the type I needed, for a 49mm OD head tube..

Nope,
The other end measures as?

Looks like a tapered head tube to me.

Read the headset info on Parktools so you know what to actually measure.

Sorted - went down to LBS this morning and they exchanged the headset for no trouble at all. Very happy as the one I needed was £17 cheaper than the one that didn't fit lol

Thank you Paul's Cycles!!



This is the one I now have to install...!
