  It's not a Reynolds one? https://reynoldscycling.com/products/rey­nolds-valve-extenders

  If so it's just screwed on. If you can't pump up the valve may be stuck closed.

  It was just over a year ago, and yeah it was well out of warranty

  I've not seen the issue, but that seems like a stingy offer from Garmin. They've sold me a refurb Edge 1000 for 75 - 85 quid twice before. One of those times was my own fault - I crashed and smashed the screen. I'd try pushing them for a better deal on a refurb (or jump ship to Wahoo if you're waiting for an excuse to do that anyway).

  Yeah, I've had this happen on 5800 levers too. Seems to be a bit of a design flaw.

  Aaand the issue was the b screw! Tightening it up a bit moved the jockey wheel away from the bigger cogs and the issue has gone away.

  Thanks, all!

  Thank you both! I'll make the B screw my first point of call to check this evening.

  I have a shifting issue on one of my bikes. The issue seems to have arisen after changing to a new chain. I know normally poor shifting is a result of cable or derailleur issues, but I'm struggling to figure this one out. Shifting is great between the 8 smallest cogs (11-21 cogs) both ways. Shifting is really bad specifically when down-shifting (shifting away from the spokes) between the 3 largest cogs (28, 25, 23). Shifting back up towards the spokes is great. The issue is particularly bad if I'm in the big ring, but is still there in the little ring.

  Bike is an Orro Terra Gravel. Groupset is full 105 5800 - compact chainset and 11-28 cassette. Chain is a KMC X11-93. I've used this same model of chain on this bike, so I know it can shift very well with the Shimano components.

  Initially I thought it was the result of a chain that's too short. 54 links rather than 55. So I added another link back in to the chain this morning but the problem persists.

  Here's what else I've done and checked so far:

  • Removed cassette, cleaned, re-seated, and confirmed all cogs and the lockring are correctly seated on the freehub.
    
  • Replaced rear mech hanger with a brand new one.
    
    

  Anyone have any ideas?

  Tonight I'm planning to:

  1. Swap in another rear wheel that I know shifts well to determine if the issue is on the wheel/cassette.
     
  2. If still an issue, replace the gear cable.
     
  3. If still an issue, swap in another derailleur that I know shifts well.
     
     

  Is there anything else I'm missing, or does anyone have experience fixing this type of issue?

• Anyone know anything about disc brakes?

  Thanks, I'll give that a go in the flat. I'll just make sure I leave plenty of rags down so no oil gets on the floor.

  In case I do need to replace the caliper, it's an easy job, right? The olive in the hydraulic hose means the oil won't just leak out all over the place and I can just move the brake hose over to the new caliper?

  BR-RS505, about 26 months old so out of warranty. I'll try brand new pads and rotors tomorrow, as there's nothing to lose even if that's not the issue (I can just stick the old pads and rotors back on there).

  If the seal is leaking, I should be able to see that visually, right? I just don't want to buy and replace calipers if that's not definitely the problem.
