Small upgrade - 11t-40t 10 spd cassette:-

I don't understand One Up at the moment. There making out standing products.

50T expander, with a new cage for M8000 and a new freehub body with a 10T.

Why don't they just make a whole cassette, sell the freehub and the cage as a whole package? I'd be cheaper for the consumer, and hell I'd probably buy one.

By the time you've bought it all it's an extra £150! Although it does seem like the perfect 1x11 on the market at the moment.
 
The mech gets changed with a new body from One Up, so it shouldn't add too much. Changing your front ring up a size, shouldn't cause too much issues with chain stress, I think? As long as you set up the alignment correctly.

My main worry is blowing that huge mech off a rock and being close to £100 for an equivalent again.

Just ordered one of those myself. Didn't see the need to go 11 speed when I realised that these were finally readily available. They weren't out when I sold my old bike last year.

Looking for some other upgrades on my Trance 1 but realistically not much to do. It has the carbon wheelset etc.

Probably some carbon bars and a 50-60mm stem although the 70mm stock stem seems ok.

What kind of stress will that not put on our mech / chain ?

You're more likely to blow the freehub with the amount of torque you could put through it although it's only ~1 gear easier than a 24/36 granny on a double/triple setup...

With that level of gearing, just get off and walk.
 
Just taken my Trance 1 (2015) down to 26.95lbs (no pedals) by going 1x10 and removing the mrp 2x chain guide. I'm not overly fussed about weight as it's an AM full susser but it's lighter than I was expecting. Rest is stock.

Just some 760-780mm carbon bars to go now and a 50mm stem.

50t rear / 32t front is almost exactly the same as 36t rear / 22t front.

You don't hear of any problems with the latter gearing so 50/32 wont be any different I suppose.

We're just getting back to the climbing ratios with 11spd that we've had with 10spd for over half a decade.
 
^^10 speed triple normally had a 24T front granny.

Nice to see you becoming more aligned with the ethos of our thread.
Soon your 100 mile rides and pedaling up hills nonsense will be a distant memory :)

In the first 10 weeks of this year I've done 50% of my normal annual climbing from the last few years, this will be a record mileage and climbing year by far :p

How is 10/11-50 needed? Seems like an early April fool...

If you live somewhere like California then; a) you are either climbing for hours which based on other forums is readily achievable on a 10/11-42 and 28-34t chainring or b) decending for hours off road which makes it irrelevant.

The climbing range ratios of a triple with 11-32/34 and 22t was almost unnecessary. A final drive of 0.67 to 0.73 is more than enough, comfortably achievable on 10/11-40/42 and that is going at a snail's pace. A final drive of circa 0.73-0.85 is still enough if you have reasonable fitness.

You don't tend to see people concerned about decending or flat speeds of the 28-34t chainring range. If doing competitive DH with uplifts then running a bigger chainring is straightforward.

If just pootling about or trekking a 2/3x10 probably makes sense as the whole bike probably costs the same as a X01 cassette.

A 50t cassette is for overpaid, over weight office works on their £8k nomad pootling along the blue runs at the local trail centres lol
 
Final drive on a 22 chainring 32 sprocket is 0.6875 and on a 34 is 0.647 which is the tripples of old.

Final drive on a 32:50 will be 0.64.

On a typical double chainset final drive for 24:36 is 0.667, 26:36 is 0.722 and 28:36 is 0.777

Ok so you can go up a vertical at 0.5mph with that ratio but in the real world, ascending at that ratio on something that requires it will either leave you spinning out or struggling to balance.

But this is going to sell by the bucket load as the pootlers have got to buy the latest kit even if they only mince around.

Evolution of gearing as I remember it: 1x1, 1x3, 1x7, 2x7, 3x7, 3x8, 3x9, 1x9, 3x10, 2x10, 1x10, 1x11, 2x11, 1x12........1x30
