is it a serious alternative to that 180 quid italian version, or is it something thats been knocked up in someones shed that has no place on a 'proper' mtb.

Thinking of going 1/10, 95% of the time i'd be fine,but just wary that i'll miss my granny ring at the end of a long day, so interested in the options (that doesn't include xx1/xo1)

Blimey. I clicked on that link and the weight made my monitor tilt left!

Otherwise: on all my cassettes the lowest gears are on the spider so presumable you'd have to shift the whole lot outwards and loose the 11T?

What derailleur do you have? Thats a proper jump in capacity but with a 1x you'd need to double check.

yes it does look a bit weighty doesn't it! No weight actually stated that I saw however. Wouldn't be looking at anything more than 38 tooth, so capacity hopefully not a massive issue.

I like gears I can twiddle away with......but, is there a rear mech that will work with that?
old style lx mech just manages a 36 tooth cog.

If you take a 36-11 cassette and change it to 38-13 you have made a cassette with a [b]smaller[/b] range. What's the point or are these just made to trick people who can't do maths out of their money?

The idea is not to increase range, but effectively to have a granny gear, without having a front mech and all that, that entails. Obviously you lose a small ring. This may be an acceptable compromise for some.

You couldn't keep the 11, and lose one of the next 2 up?

I still think you are missing the point. To get the same granny gear you are after you instead change to a smaller ring on the front. As the 36-11 has a bigger range you lose less at the other end with the same result at the granny end.

Or use a smaller ring and a Shimano Capreo hub which has a 9 tooth sprocket ? Lowering the gearing but at the same time keeping the same top ratio with the 9 tooth sprocket?

Well yes, that goes without saying. Presumably this is for people who are already pretty small on the front. I have a 32t ring, I see that you can now get a 30t from Raceface but yeah, these are I suppose your next option if small at the front and you still feel like you want more.
I find 1x32t - 11-36 gets me up most stuff eventually.

#1 lose weight by removing front derailleur and shifter
#2 gain weight by adding jumbonormous cogs to rear cassette

I must be missing the point with these cassette adaptogizmos.

2x9 seems to work rather well for me TBH.

See that - it looks rediculous. see your bike with the new massive cog - it looks even more rediculous than even that.

I've just paid £104 for my General Lee adaptor from bike-discount, never seen them for £180
