When I built up my RAG+ last November, I used a Brand-X Headset Compression Device in the fork. I've noticed a bit of play in the headset while breaking, so have been tweaking it every now and again. Everything seems fine when I do it up, but then after a while I get a bit of play again. It's very loose in the steerer tube, and takes a lot of pre-tightening to get it to stick.
So I think I'd like to replace it with a better one, that is tighter in the tube by default.
Can anyone recommend a good 1⅛" headset compression bung please?
Yup, watched that. The Brand X one is supposed to be for 1⅛” steerers, but is ridiculously loose when you first put it in. The Planet X one looks a decent length, the Spesh one seems hard to get hold of...
I bought one from the Bikemonger a week ago... Only one ride in on my new Selcof rigid forks... It defo grips and holds well. But longevity? That'll have to wait. Super swift mail out service, with a fiendly email interaction all the way. It comes with a shim that I havcen't had to use. I think it's in case your fork inner is larger diameter (well I guess that's obvious isn't it).
My forks are 1+1/8th steerer,with 1.5 lower. My understanding is that the 1+1/8th top is the same on any 1+1/8th fork. I enquiered on this forum for advice on whether I could use a road bung. Everyone said yes. I was gonna borrow from my road bike until the new one arrived, but it came so quick I didn't need to.
@k1100t one thing to note is your top cap bolt... you may need to find a shoter one. I don't know how your current one is, but this one has a lmited threaded depth for your top cap bolt. It's because the bung's own tightening bolt is hollowed out for the top cap one to screw into. I presume this is common across all bungs. But I had to swap my top cap bolt to a shorter one. I just used an old hex headed bolt that was the same thread. It's a really common size. I guess you could easily cut down your existing bolt also (if it's too long). Anyhow, you may have already overcome this with your current bung. Good luck
I have a spare deda expansion bung. Bought it for my kinesis maxlight mtb fork but the steerer walls were too thick for it to fit. Brand new in box yours for a tenner if you'd like it.
Carbon grip paste? Or, if cheap, toothpaste?
Also, make sure your headset cap is ACTUALLY tightening against the spacers, rather than sort of tightening against the spacers and sort of tightening against the actual end of the fork tube.
@easdoesit thanks for the offer, but I've already bought that one from Bikemonger.
@continuity there's a 2-3mm gap between the top of the top spacer (which is a 10mm one) and the steerer tube, precisely for the reason you mention.
FFS! Bought a new Cane Creek 40 Series IS42/IS52 headset, and I can't get the 🤬 thing to compress.
Bike is now in a bike shop, as I give up...
