Any recommendations on a sprung chain tensioner that can be used with an Alfine hub? Needs to screw into the hole that the rear mech uses; I’ve been looking on the interweb without much sucess. 😯

It will a whole lot less faff if you get an external EBB like the Forward Components one

There is an Alfine specific tensioner

That’s exactly what want so how much are they in UK?

Forward components or Excentriker if you have money burning a hole in your wallet. Otherwise, a singleator style one off ebay for a tenner will do the same job for a lot less money.

I do have chain tensioner but for whatever reason I keep getting some “clang” sound from time to time when I am pedalling on my single speed.

Front chain ring 32t, rear 18t with Sram PC69 chain and a Surly chain tensioner. I wonder if I need a half link chain (only one not the entire chain) to get rid of the “clang” sound.

Not sure what that could be. If you have a chain tensioner – a half link won’t benefit you much. You might get a better chain wrap around the rear sprocket but other than that not much else.
PC69 is a nine speed chain. So will have narrow links. If you are running an unramped single speed specific front ring with a BMX stylee rear – this chain is probably not suitable. You should just buy a single specific chain. They’re also much cheaper than a PC69.

I have a DMR tensionseeker II. The design works well enough, except the fasteners that allow you to set the right tension are made of cheese-like alloy and fiddly to setup. The Surly eqv. might be better.
