Thinking of going 1x - a couple of questions

dirkpitt74

The cassette is getting worn on my HT and it could do with a new one - so thinking of possibly going 1x10 with a wide range cassette.

If I ditch a ring up front and go with a N/W do I need to alter the chain line at all?

I assume it's the outer ring that gets replaced with the N/W?

Is it worth going oval too?

What about re-sizing the chain? Do I still wrap it round the largest rear/front and add 2 links?

Thanks

Double or triple crankset? Triple use the middle location double use the inner, outer gives a worse chainline.

Chain is the same as before, single/big with suspension in longest chain length height and overlap +2links.

Oval is reckoned to be worth about 1% so your call.

You may need shorter single ring chain bolts depending on the ring.

Currently got 2x on front.

So put the NW ring in the inner location so its running the bigger gears at the back on a better chainline, it's slightly better than using the outer location for the chain.

If you can find a chainring that fits an inner bcd....

So is it worth taking the drive side spacer to the non drive side of the bb?

You can, but plenty of manufacturers do NW rings for the inner now.
