Is This OK To Do ?

I had a choice to either swap out my busted BB(stripped splines) for a longer one or do as the pictures show, to flip the fixed sprocket which gaves me a perfect chainline of 41-42mm.

The chain is close (2-3mm) to the spokes... is it alright..?

Im just wondering if it's safe ?

I'm disappointed, i thought this was going to be another "what colour should I paint my frame?" thread.

push the chain with your fingers towrads the wheel, if it doesn't touch the spokes, it won't whilst you're riding...

7mm between chain and spokes should be fine but it looks like the chain is touching the spokes in the picture. Also it seems odd that the chain line should change when you flip the wheel. Have you screwed the cog on with the shoulder outwards?

yep, shoulder is outwards, so the cog sits further in by about 7mm.

That looks fine to me, if it doesn't touch... then it doesn't touch and it's OK. Like ^winston says, if you can't push the chain much nearer to the spokes then it's not going to get there when riding. BTW, you were right to spot that was a BB lockring spanner I referred to in t'other thread, a whole bit of my rambling went missing which was along the line of 'if you get sold a spanner purporting to be for sprocket lockrings but ain't...' - there's a lot on eBay of course.

looks ok, but when you can get a new b/b

nice one guys, just wanted to check :)
