    You need another spacer. The cap should be tightening down onto the spacer, not the steerer tube

    Did you remove a spacer when you lowered the stem?

    Oddly no.

    And I took the smallest spacer off my spare bike and it's too much.
    I'm going to need a 2 or 3mm spacer. Smallest I have is 5mm

    Might be time to bit the bullet and cut the tube!

    The cap is thicker in the center
    Spacers almost flush with steerer top

    Replace the top spacer with a thicker one that gives you about a 3mm gap and your problem is solved I reckon

    Or replace one of the spacers with a thicker one ;)

    This is the issue.
    Went to take off again.

    Loosened the cap
    Then tightened the cap to a reasonable tightness.

    There's a 0.5mm gap between the cap and the stack

    Remove the top cap and check the expansion plug in the steerer tube. If it has come loose, when you tightened the top cap, the expansion plug may have been pulled up a bit.

    Make sure it’s tight and make sure it’s down far enough in the steerer tube.

    Are these any good? Having bad luck with punctures right now, three in three weeks.

    Bought a bike about two years ago. First one with disc brakes, and when I asked how long the brake fluid would last, I was told "forever".
    Are the discs wearing out, or is the brake fluid being used up? The brakes are nowhere near as good as they used to be.
    The front ones still slow me down on a steep hill, but it's not good enough any more.

    Change the pads? Bleed air from the fluid?

    yeah, my first thought would be brake contamination or brake wear if you've had the bike two years.
    you might be able to easily see how much meat is left on the pads if worn.

    No idea how to do that, but I'll look into it. Cheers.

    contamination would often make itself audible in the wet. the brakes would squeal.

    Thanks for all the answers.
    It seems that the problem is with the brake pads. I'll be leaving the bike in with the experts in my local bike shop. They know what they're doing, and I'm only capable of fixing a puncture.

    Also, the crank has been sounding dodgy for over a year, so I need to get that looked at, too.

    Thank you all.

    well it just says 4, but the 26 must be inches, so not sure they would mix imperial & metric.
    it cant be 4 inches, they are about 4o mil now that i think about it.

    ill prob get 38 mil or something like that..

    How old is the bike? There was a 26 x 1 1/4 (26 by one-&-a-quarter) inch size on old Brit bikes; maybe that's where you're seeing the 4 in the marking?

    26" is a very common standard for wheels, mountain bikes used that size for many years.

    The tyres/wheels are not all interchangeable though. The old size I mention has a BSD of 597mm, & the mountain bike one is 559mm.

    not specifically a bike maintenance thread, but there's no universality of connectors for floor pumps, is there? i threw the hose out on this ~20 year old pump a few years ago (it had perished), and it's been knocking around the garage ever since. should just bin it if a new hose cannot be bought (which would probably be for the cost of a new pump anyway!)

    If you've any way of measuring threads, internal diamater, or whatever, I'll check it against my cheap aldi/Lidl pump. If it's the same, I'd hang on until the get them in again, you'd have a replacement hose for about 8 quid

    Has anyone here taken their bike to a bike shop to have bottle cage mounts fitted using Riv nuts?

    I'm trying to fit a battery but unfortunately the existing bottle cage mounts are slightly in the wrong position plus I could use an extra two holes for a more secure fit.

    Hey,
    I've never taken my bike to a shop for it but I have fitted rivnuts for bottle cages before (as recently as yesterday).

    If it's something you would consider doing yourself, feel free to ask any questions you might have.

    My bike has 20 x 2.25 Kenda tyres. Got a puncture the other day. Removed tyre and tube and found glass in tyre that protruded slightly inside the tyre. The strange thing is that the hole in the tube was about 4 or 5 inches around the tyre from where the glass was.

    I checked the inside of the tyre thoroughly and found one thing other than the glass. Very close to where the puncture occurred, there was a small pimple of rubber on the inside of the tyre. It seems like it was there since manufacture and there's no sharpness.

    1. Is it possible that the glass might have caused a puncture that appears that far away on the uniflated tube?

    2. If that "pimple" in the rubber of the innerside of the tyre might have caused the puncture through friction, what would be the best way to remove it?

    3. The glass went through the tyre and punctured the tube. As the tube deflated, the tube moved/twisted so when you removed the tyre, the hole in the tyre and tube were in different locations?
