    Loose-ish Hope Integral headset cups on 429

    G'day folks , im the owner of a new 429 Pivot frame and im in the process of collecting bits and building it .

    Ive got a question on the headset , while fitting the headset which is a Hope Integral headset , the top cup did not need to be pressed in , it needed to be really straight but i tapped it in with the handle of a screwdriver , thinking this might have been the tolerance out on the Hope headset , i removed it again and tried the bottom hope cup with the same result , then the top hope cup on the bottom which was again tight . Meaning that the frame is very slightly bigger on the top side of the headtube .

    Now it still needed tapped in gently and tapped out , but when its fitted flush and level , it can be turned in the frame by hand , still a good twist is needed to budge it though .

    My first thought was new headset , now im thinking thread locker ? As the headset is not loose as such , its just a really good fit .... ideally being a tight fit obviously
    I am going to grab a set of Verniers in work and measure the 4 surfaces , both frame openings and then the headset diameters.

    I did a google search and on here and found a few topics on similar situations , some of them have had the top cup falling out and epoxy resin'd them in , others have used thread locker.

    epoxy loose headset cups?

    Has anyone else had a problem with their headsets ?

    BTW: Pics to come on the "post your pivots" when its done.

    Zero stack is 44mm /

    Ozzy, i think the integrated CC is 41mm. What I think you need is a ZeroStack 44mm. I know the Pivot uses a 44mm. Measure it to be sure. Rich

    I would say do not ride your bike with a headset that fits in like that. Find out which part isn't made to spec. From what I've read, it's likely the Hope - seems like there is always a headset or hub post about stuff that's just slightly off.

    Sorrry for the hijack, but can anyone recommend me a headset with a nice tall top cap? I dont really like the look of the 15mm of spacers i have under my stem on my 5 and maybe a headset with a tall top cap will look a bit cooler. Thanks!

    Well Ozzybmx, if I could recommend a replacement, there is no better than Cane Creek. They invented threadless headsets and their 110 line is very, very good.

    Not so good news !

    The Hope integral headset is 44.08mm diameter

    The top headtube measured in 6 positions -

    44.09
    44.17
    44.08
    44.15
    44.11
    44.12

    Will be contacting the place i bought it from and have emailled Pivot. Not a good start by the looks of it

    I looked at the specs for the cane creek 110, since it is known to be an industry standard. Your measurement of the hope headset seems to be spot on with the tolerances for the cane creek 110 - 44.08 +/-.02. According to the same spec sheet the headtube on your frame may be a little on the large side - they say 44.00 is ideal.

    Actually that headtube drawing says that 44.00 is the largest the headtube can be with a minimum of 43.95. Another way to write it would be 43.975 +/- .025.

    The bottom cup of my Cane Creek ZS-1 is loose like that. I had a creek so I did a clean and re-lube of the headset when I noticed it. I used some sleeve retaining fluid (green loctite) on the lower cup and put it all back together. Seems fine. I would think it would be fine as long as you keep the whole thing tight. I do have a King headset ordered. I'll take some measurements when I get everything a part.
    RIDE ON,

    You can also peen the cup. Use a punch. Use an old handlebar to act as a dowl and lock it in a vice. Slide the cup onto the bar. Then make 6-8 eavenly as possible around the cup where it inserts into the frame, about half the distance from where the bearing sits and the end of the cup. Then use a little green loc-tite and press it all together.

    This is a means to an end, if Pivot doesn't send you another frame.

    Well, since we are sharing headset fit stories... another option is to take an aluminum can and cut a few slices of it as a shim. I forget exactly why, but 1" road bike steers used to have 2 standards and one of them you had to do the pop can trick on or it would be loose. Maybe it was a french steer with an italian race... I forget.

    If Pivot gets back to me and confirms in Black and White the headtube is out of spec , i cant see problems in getting a new frame sent from the importer .... waiting on PIVOT though , been 2 days since i emailed them with no reply yet.

    Try again in about 45 mins. Or get some sleep and call before 5pm local (or 10 am your time)...

    What a response from Pivot

    My frame is being picked up by courier and shipped back to the distributor for inspection, i have no doubt the headtube is out of spec , so they said they are sending a new frame once its been confirmed !
