I've just fitted a new(ish) chain to replace a badly stretched one that was tending to come off. But the other problem i had - slightly sluggish changing up - remains and top gear (smallest cog) is elusive, needing several turns to engage. When the chain is on the smaller crank chainwheel it won't engage the smallest cog at all.
I've adjusted the h screw and b screw but it made no difference. I don't think the (internally routed) cables are binding but if i help the mech outwards the chain drops down OK.
The new chain has 58 links but the online calculator suggests i should have 59 so i will add a link when i can get hold of one (no-one seems to sell them) but i'm not sure if that will fix the problem. The chain i replaced only had 57.
It seems as if the spring in the derailleur is too weak, but i don't think there is any way to adjust it (?) It's a Sram GX EA 10sp.
Can anyone suggest a solution please?
