I only joined last week so this is my second post on the same subject I suspected I had put it on the wrong Board when I noticed this board was for Triumph bikes only. Sorry for that.
No need to be sorry! Nice to have you here, the more the merrier!

I seldom see a QD without wear, but keep them greased and they last for a long time anyway. To renew the drive a new hub and a new sprocket is needed, so it involves rebuilding the wheel. This often leads to a desire to renew the spokes and rims, and you don't want to put an old tire back on your shiny new wheel! New tire on order. And you'll want to run a new chain on your new sprocket. Renewing the gearbox sprocket is a good idea then of course, and then you discover that the clutch plates have seen their best, the clutch shock absorber is well worn (they don't last very long) and it makes sense to renew the half worn primary chain.
Then, as you enjoy your smart new rear wheel, you cast a glance at your front wheel...

Sometimes leaving well alone is the better plan...
