Swapped 2×9 to 1×10 but only lost 150g!

Just swapped all my bits over to 1×10, largely like for like apart from shorter cage mech. Xt for Xt, SLX for slx, but SRAM pg990 11-32 for 11-36 Xt.
I’ve only saved 150g, that damned cassette is 103g heavier!
The shifter is 31g heavier and the mech (shorter cage) is 9g heavier. Progress….

On the plus side my reverb lever now fits under the bar on the left.

For those that care I have used a Blackspire Einfachx ISG05 with a modified Stinger (as I already had one).

Not added a chain yet but it looks like it work to me 🙂

No doubt my KMC 10 spd chain will be ridiculously light… And that huge piece of outer from the front mech 🙂

Yep more cassette weighs more. It’s still progress as the range is better. If you were that bothered by weight you should have checked first.

That is me checking. It was all bought off here at reasonable prices so can always get sold again. Then again, I would hate to miss out on a new fad. Now where do I buy 650b 🙂

Did you get a standard XT mech or Shadow Plus?

From 24 speed, bit of xt bit of Deore to slx 10speed saved 370g.

What did you expect. 5kgs lighter?

Have a poo before you ride

Northwind – standard.

Stevewhyte – nope but I didn’t expect a newer SLX shifter or XT mech to weigh more. Or an XT cassette to be 103g heavier.

Apologies for expecting more 🙄

I looked last year at going from 3×9 (34) to 2×10 (36), and realised that even repacing XTR with XTR I wasn’t actually going to save any weight.

Not sure how the range is better either…

Suspect my setup is heavier adding in the chain device! Not about saving weight though for me, more about simplicity and aesthetics 🙂

I hate front mechs.

That is all.

10 speed has more range than 9
Depending on your setup/riding/legs it can be the difference between 2×9 & 1×10. Had you gone 2×10 you would have been heavier but the lower gear should make it better.

However you expected a massive saving in reality your into the £1/g territory so that should represent about £105 of weight saving 🙂

You’ll end up with thighs like barrels though Jason.

Its not about the weight saving, its about preventing you from dropping the chain off the front ring.

But if you add the weight of one of them blackspire stinger chain devices to the weight of a 2×9 setup then it probably doesnt look as bad as you’re making out.

If you want to save weight, dont eat for a few days before you ride.

I can’t get my head round weight weenies with dropper posts…?

Why not? Proper weight weenieing isn’t just making things light, it’s making things light while avoiding unwanted sacrifices. There are weightweenie downhill bikes.

I recently looked at swapping my 3 x 9 for 2 x 10. What you lose on the front chainring you more than gain on the cassette particularly if you go for the 11-36.

Less of a change on a 11-32 or 11-34 but then you aren`t really gaining anything over what the 9 speed options give.

Still like the idea of 1 x 10 or 1 x 11 though for the loss of the front mech and tidier set up if not the limited weight loss.

“10 speed has more range than 9”
Not in all cases

1×10 over 1×9 can yes
*3×10 sram over *3×9 yes
3×10 shimano over *3×9 no, has less range. Even with a 11-36T casette. The 42-32-24 combo has a higher lowest gear and a lower highest gear

*44-32-22T

“I can’t get my head round weight weenies with dropper posts…?”
On certain downhills you can go faster with the saddle down, you have to stop to put the seatpost back up, which is slower?
On those rides where you can go faster with the saddle down, it’d be faster to have a dropper than leave the saddle all the way up
That or they’re something else to throw money at

“3 x 9 for 2 x 10. What you lose on the front chainring you more than gain on the cassette particularly if you go for the 11-36”
eh? egs?
afaik available 2×10 setups use at lowest a 24T inner ring no?
a 24-36 combo is a higher/harder combo than 22-34T?
Same at the top end. No 2×10 combo has a 44T chainring?

Same at the top end. No 2×10 combo has a 44T chainring?

Thats because most people have given up pretending that they use a 42/44t ring for anything 🙂 Not all setups are the same, just because something comes in a box with x,y,z chain rings doesn’t mean thats the only option.

The 10speed cassettes I have seen combined with 2 sensible chainrings give all the useful gears over 2 rings, better than 2×9. When my gear finally gives in/get a new bike 2×10 all the way. 2×9 already covers most of my needs but lifting the front up to 24/26 and the middle to 38/40 would be a good option.

James,I was referring to weight rather than range with that comment.

Eg:10 Speed 11-36 cassette is best part of 80g heavier than an 11-34 9 speeed which is not negated by the loss of one chainring.

So you may aswell stay with 3 x 9 ,keep your granny than go 2 x 10 if you were looking purely at the weight aspect.

I have included the Stinger when I did my sums.

Not sure I can be classed as a weight weenie as my Mega (not the is lightest frame in its class) covered in XT/SLX kit and has a Reverb.

I’m not even doubting whether its a good idea. Only slightly disappointed
that newer versions of components are heavier.. 8)

I guess shimano care more about performance that weight. 200g is nothing and makes sod all difference.

As do I.

Presumably you have never bought a lighter/stronger bike or component?

You have too much chain device for a start. Get rid of the Stinger and you’ll save more weight. Have you still got a bashguard? There’s no need for that either.

And how did you think that adding more gears would save weight per component? One more click on the shifter. One more cog on the cassette (although admittedly a much more robust one that a Sram 990 which is made of cheese). A shifter with a longer arm to adjust the leverage ratio. Of course they were going to be heavier.

I swapped and it saved me around 400g per bike losing 2 chainrings, a front mech, cabling and shifter and gaining an E13 XCX chainguide.

Depnds on the bike and where you ride, the mess I’ve made of my silentguides outer would beg to differ with your oppinion.

As for weight saving, my Pitch is at 32lb so really could do with loseing some if you believe MBR, but it rides so dam well I can’t be arsed to swap anything, even if I did swap everything for the lightest comparable bit’s I’d probably only be £3k and 4lb lighter, which isn’t going to win me any KOM’s.

Why not? Proper weight weenieing isn’t just making things light, it’s making things light while avoiding unwanted sacrifices. There are weightweenie downhill bikes.

well done – and now you will be tearing a hurnia, pogoing up and down and blowing out of your ass trying to get up long steep drags.

I cant wait for this 1×10 fashion to blow over and for everyone to screw there granny rings back on so I can stop freezing at the top of climbs waiting for you all to catch up.

hee hee 🙂

Funny that, my experience is that 1×10 makes you climb faster because, well, you don’t really have a choice.

+1, it’s like SS but for FS bikes so you can climb in too high a gear sitting down.

Had the SS’ers already got bored and left you?

You all seem to set off at a fair old lic Il say that – but anything more than a couple of hundred yards of steepness and Im soon passing people hunched over and coughing up chunks. Happened to me this weekend in an enduro race- trusy old granny’s are the way forward unless you live in Holland – and then you dont need a “mountain” bike at all

Are you really that bothered about how/what other people are riding though?

Bash has gone and my stinger doesn’t weigh much, it’s now on its second butchering so there’s not much left!

And I’ve been using 990 cassettes on both bikes for the last few years without any problems.

As for coughing up chunks, you may be right. If you are I will post up and admit. Certainly won’t make Snowdon as easy.

1×10 made the climb up Snowdon slightly easier for me, the weight saved from the front mech and shifter meant that the push up was slightly less of a chore 😀

You need fitter mates not more gears.

Not too many single speeders in the Munros – but perhaps they were travelling too quickly to be seen

Cheeky- they were no friends of mine – they were in the enduro

Lol @ Stevede

I’ve only saved 150g, that damned cassette is 103g heavier!

Is that First World Problems thread still running? 🙂
