Chainsets XT or SLX?
Just started using slx after no end of grief from race face deus. I got mine from Ribble for £55 which to me is a bargain but you dont get the BB though. Shifting is spot on so no complaints. As for weight, go for a dump before you go riding. As for the 'bling' aspect, if you can afford it then why not.Posted 7 years ago
Is there any point buying XT over SLX? I have had various SLX components and they have all been as good as the XT they have replaced and practically the same weight. At £90 against £130 – almost- is an XT chainset worth the extra? Are the bearings the same, are the chainrings still made of butter?Posted 7 years agomboySubscriber
There's about 40g weight difference (XT weighs less of course) which is naff all.
Both have a composite middle ring which lasts a lot longer.
There's pretty much nothing in the stiffness.
Unless the 40g is really worth another £40 or so to you, SLX are significantly better value. That's not to say they're better though of course! 😉Posted 7 years ago
I think SLX looks more like a low rent crankset and nothing like XTR apart from being two tone.
XT just has a nicer design IMO:
I can't see why anyone would say XT is "better" just because they have SLX. How is it better? It's heavier and no stiffer, more durable or anything.Posted 7 years agoNorthwindSubscriber
From 10 feet away you'd be hard pushed to tell the difference between my XTR and SLX. Except that you can still read SLX on one whereas the XTR logo has obviously worn off. The actual crankset looks very similiar but the SLX big ring does look a bit nasty, lucky I take those off really. XTR has a nicer looking finish but ironically it's not as durable.
XT is still a lovely chainset mind but if weight is your thing, you could spend that £40 better elsewhere most likely. SLX crank is one of the best bits of bike kit out there just now IMO.Posted 7 years ago

I assume you mean SLX instead of XT there. IIRC Shimano claimed the SLX cranks were stiffer at the time of release. Also the double version has steel pedal inserts, but looks are subjective. You could probably argue that the XT is a (very slightly) better chainset, but VFM wise SLX poos all over XT IMO. I don't own either.Posted 7 years ago
What went wrong with it?
Middle and outer chainrings wore very quickly, BB died.
Poppa – I did mean that but the VFM wise, why does anyone get an XTR chainset? It's not a whole heap lighter but it's three times the cost. I also got XT SPDs over M540s – only a wee bit lighter and more expensive but hey ho, that's the biking industry for you.
VFM aside, the XT is lighter, has a steel and carbon middle chainring and IMO, is stiffer – just look at the way the crankarm sits more snugly in the spider.Posted 7 years ago

I know i'm being pedantic now, but I can't resist. The SLX also has a steel/carbon middle ring (on the triple), and a steel inner ring. I suspect stiffness is a bit of a grey area, after all Shimano claim the SLX is stiffer than the XT.Posted 7 years ago
Which XTR is it? What is wrong with it?
It is an Octalink HT1 – I need to replace the BB and chainrings. The BB will cost me £55 and the rings maybe 25 to 40 each. The SLX comes in cheaper and I'll have a choice of bearings when the Shimano ones die.
I can't seem to get much life out of the BBs. If I am lucky I'll get 1,000 miles out of one but in reality I'm changing BB twice a year.Posted 7 years ago

Unlike this 'fact' eh? 😉
Well, it apparently came from Shimano so presumably holds much or as little weight as anything Shimano say.
'Shimano claim the SLX cranks are 100 per cent stronger than XT, and from the abuse they’ve handled since we’ve had them, we’re ?rm believers. They feel as stiff as most downhill cranks, and ramps and pins on the rings give slick and quick shifts.'Posted 7 years agoclubberMember
Buy the XT if you either have spare cash to blow or want the name or prefer the looks. Don't try and pretend that it can be justified logically. Buy the SLX and spend the difference in price on other components which will save more weight.
Cost of replacement rings is irrelevant BTW – you can mix and match as you choose when they wear out.Posted 7 years agoThree_FishMember
The SLX arms (no rings/BB) have been found to be lighter than the XT, although manufacturing differences could make it so that a set of lighter XTs could probably be found. The main weight difference between SLX and XT is in the rings.
The supplied BB cups are identical (bearings and seals) for SLX and XT.
Although the SLX uses a composite middle ring, it's not the same as the XT and is heavier. The big ring is simply not comparable. I have pictures of the weight differences between the rings, just not at this computer. All three rings use entirely different materials and the two larger rings have a different design.
I suspect that most riders wouldn't tell the difference in ride quality between the two sets, so could just make their decision based on aesthetics.Posted 7 years ago
From a review over a year ago – the XT chainset has since been heavily revised.
But what would I know, I've only run both on the same bike after all…
Well, the new XT has the same crank arms as the old XT so I don't think the age of the review means anything. But in any case you have the experience of riding them, not me.Posted 7 years ago
If its for general riding SLX, if racing XT or XTR
This is often said but how is plus or minus 40g going to impact on your racing ability? One muddy section and it won't matter if you are running XTR or Deore (from a weight POV).
Given that most of us are going to be also rans in any race we enter, weight is largely irrelevant. If there were other aspects such as poor shifting, fragile chainrings etc then I'd be inclined to agree. If, everything else being equal) there is little operational/functional difference between the two then it all becomes subjective… surely.
When I was a few years younger than I am now (ahem) I had my eyes well and truly opened when I went out for a ride with a guy who had been offered a ride with Cannondale Volvo (GB). I had my blinged out XC bike, XT, XTR all over it, sexy wheels, super lightweight tyres the works. It was a bit muddy and sloppy but nothing too bad. He turned upp on a £150 Univega with slicks on it. It was his uncle's bike and he had just come back for the weekend (with his riding kit, shoes and a pair of pedals.) Anyway, my race head buddies and I went out full of confidence htat we would make a good show up against the elite rider.
Sadly, we didn't see much of him, had it been dusty we would have been eating his dust all day. He would wait at the end of the singletrack while we were red lining it, then cruise along the fire roads at (our) TT pace. Anyway, after a few hours of torture he got distracted by a pit full of jump bikes. He then proceeded to show them up too. (Don't get me wrong, he wasn't showing off – he was just several classes above everyone else… and a really nice bloke with it.)
My point being, he showed me quite graphically, that it is the man/woman on the bike not the bike or its equipment.
If we want XT or XTR or whatever, that is up to us but ,functionally, why pay more for the bling bits?Posted 7 years ago
What's happened here? This is usually a weight weenies website.
50g may only be 50g but it's still useful when getting a light but robust bike. And silver finishes are smoother and more aerodynamic so therefore faster…;-)
XT SPDs are very slightly lighter than 540s – but it's only a few grams. They also happen to be black which matches my frame…Posted 7 years agoThree_FishMember
How much stiffer do you reckon it is, just by looking at the increased snugness, 12% ?
You'd need to know the snugness meausurement, but snugness will typically increase stiffness by a ratio of around 1:1.22 within a 17cm (approx.) radius of the axle; so a 10% increase/difference in snugness will translate to a an increase of around 11.22%. I wouldn't like to say what the figures would be for a 175mm crank.Posted 7 years ago
