Shimano WH-M975 Wheelset

4.13/5 (16 Reviews)
MSRP : $1199.95


Product Description

Ohhh mommy. The tubeless, disc-specific Shimano XTR M975 Wheelset is scandalously light, super stiff, and looks supremely sexy blazing across the finish line of a cross-country racecourse. Anodized Scandium allows the rim walls to get fashion-model thin without sacrificing strength, and the titanium rear freehub body plays a similar role in the XTR Wheelset's 1525-gram weight. Centerlock disc rotor mounts provide a quick-changing system that's also extremely responsive due to the many points of

Strengths:    UST, Good Hubs, Lightish, Durable

Weaknesses:    Rims a bit narrow to run high volume tires (i.e. over 2.25) and low PSI - get a bit squirmy.

Bottom Line:   
I've ridden these for two years (including five endurance races) and have had zero problems with the hubs, zero spoke issues, and only required truing once (front wheel slightly out of true after crash at Gunnison Growler). I weigh around 200 lbs. and haven't notice any flex. Great UST for endurance racing - my intended use when purchasing. I got them for a good price in the offseason (i.e. December).

Strengths:    Light, Strong, Roll smooth

Weaknesses:    None that I've found

Bottom Line:   
I've ridden some pretty tough trails on these wheeels and I've been impressed that such a light wheelset is so durable. They stood up to the riggers of moab trips as well as weekly rides up and down local trails like National(phoenix). They are also super smooth; I feel like I could coast forever when riding them.

Strengths:    Stay true, light no flex, great acceleration

Weaknesses:    non so far

Bottom Line:   
I dont know what you other guys are doing to destroy these things,(perhaps its plain bad luck), It took me 12months and 1000klm to get round to servicing the bearings in them (very slack of me i know), and guess what, they looked like new, have checked for true a couple of times over the last 12months, especially after a 4hr down hill enduro, and they needed next to no truing up, i have a set of cross max and think the XTR is a way better wheel set, so much so that i use the cross max for general riding and keep the XTR good for racing.
I give five for overall and five for value because they came as a full xtr groupe set on the bike

Strengths:    Awesome, light wheel. Has held up great.
Bought it online and installed the cassette, discs and skewer - easy enough to do. Have not had to true the wheels.


Weaknesses:    Spokes break and they are expensive! $8 bucks a pop, but what do you expect for a $1000 wheel?

Bottom Line:   
Great wheels, light weight, looks cool.

Strengths:    Fast and light

Weaknesses:    The rear axle I busted this like the other fella's here below me. What the funk I thought it was my 1000 watts of power now I see I am not alone. How dissapointing that the price tag can not produce a wheel that has a solid axle. The replacement part is 100 bux and on back order from shimano as we speak.

Bottom Line:   

Stay away too much moolah for something you are gonna bust up, for shame shimano !!

Strengths:    Super light, silky smooth and good value for money on paper when compared to competition.

Weaknesses:    Spokes and hub axle!

Bottom Line:   
Great wheels when they work!

I purchased mine in Oct 07, by Dec 07 (after only a few hundred K's the rear hub axle had snapped right near the end. It then took Shimano until about April 08!!! YES 08 I kid you not, to source a replacement axle under warranty....WTF!!!! Apparently they had none in Australia at the time and had to source it from Taiwan or something.

After getting wheel on bike again I had a string of spoke failures and now the rear hub axle has broken AGAIN!

Date Reviewed: November 7, 2008

Strengths:    Very strong scandium rim and FAST hubs. These wheels are incredibly smooth and light. Red nipples match the CK red of my headset exactly. Rare and exotic. When they hold up they will let you fly.

Weaknesses:    The spoke design. The nipples on the rim interface are beefy, but the spoke has another threaded piece where it meets the hub. A tiny little piece called a hub nut. These are way too easy to break. and, guess what? They have been impossible to get from Shimano since June. The same hub nut is used on the tubeless Dura Ace wheelset and same problems abound. This is the dirty little secret of these wheels. They are sold as everyday use race weight wheels. I have been through three rear spokes because of this and have not been able to use them all summer/fall while I wait on back-ordered parts. try and get someone to really try and find these 50 cent parts when the launch of the 7900 DA Gruppo is going on. Will drive you crazy. I am going back to Mavic where I know i can get parts.

Bottom Line:   
I wish so bad these were the wheels I thought they would be. Look sweet, fast as _, light baby light. Three broken hub nuts in 5 rides is unacceptable. Nice try, but no support. I guess if you had a team truck in the parking lot filled with spares.... I wouldn't dare ride these things more than a mile from my car. There are other choices at this price point that are proven and reliable. Look at i9's or Mavic SLR's.

Strengths:    Lightweight, true UST rims, quality materials / build, centerlock rotor mounting.

Weaknesses:    nothing yet.

Bottom Line:   
For XC - I couldn't see any better value for money in any other UST factory wheelsets around this price. Look great as well, in a stealth kind of way. Running 2.25 tyres to give a bit of cushion to the hardtail - hopefully helping protect the wheels a bit too.

Strengths:    These came stock with my bike, GT Marathon Team.
Light, fast, stiff, low maintenance, nice looking!


Weaknesses:    Lightness makes these not bomb proof.

Bottom Line:   
I got these wheels stock with my bike. For the last 6, almost 7 months, have raced, trailed riden, downhilled, jumped, crashed a few times though nothing major, and have hed to true the rear wheel slightly they didn't even charge me cuz it was so minor.
I have a few very minor dents mainly on the rear rim, they are more like scratches. You guys just need to avoid hitting them! Can I say SKILLS???? Don't freaken hit them!
OH yeah, I broke 1 spoke, with some stupid rock, it was crazy though, it did not brake from the nipple, it broke from the HUB side!!! the guys at the LBS where like, WTF, never seen that one before. But yeah, paid $9 and got a new spoke, and no issues since then. This was like 2 months ago.
These wheels are really good, just be SKILLFUL when you ride okay?, don't go crashing into things, DUH!
My bike is has a full carbon frame so I have taken care to rely on my skills to avoid impacting anything hard with my bike or components, just work on your skills and all Super light XC bikes and components should last you as long as if they were made for downhill.

Strengths:    very stiff and light the hubs are very smooth and they are ust

Weaknesses:    the spokes may come loose after 1 year of racing
the hub spoke attachment


Bottom Line:   
this wheels are for xc racers only!! they are very light and stiff they are great but after a while the spokes can come loose, since this wheels are very light the walls of the rim can easily dent if you hit it with a rock or somthing, so I recomend to use this wheels only for racing and have another wheelset of training.
the rear hub is the strong part of the wheelset it rolls smooth and it requires very little maintenance

takes a tubless tire really well trail inflation with small pump not a problem.




Weaknesses:    rear hub.
rear hub axel body broke clean through will on a trail ride. i weigh 85kg and ride a HT fairly hard. maged to ride out on the skewer. i am also developing concerns about the free hub skipping allthough happend on same ride so ill see when i rebuilt the hub with new axel.


Bottom Line:   
great but you may have to replace rear axel body if your ride agressive xc. cost of replacement is $60 Au$ so no biggy.

Strengths:    Light, Stiff, rolls well.

Weaknesses:    None so far

Bottom Line:   
Very impressed so far!
I only ride with nice wheelsets and these are good.
Stiffer than Crossmax on front, roll better and smoother,(early days though).
High quality and well made.
I also prefer the feel on the trail while riding from XTR.
Crossmax feel a little dead at times but they are bullet proof!
I will post review after a few thousand kms to see how XTR hold up. Only nervousness is the freehub. I have the updated freehub so hopefully none of the problems of the earlier sets. Best value by far from chainreactioncycles.com at $550 US of any wheelset out there!

Submitted by Tom a Racer from Grasse, France

Date Reviewed: September 12, 2007

Strengths:    Light, "native" tubeless, stiff for light wheels

Weaknesses:    Durability not up to XTR standards. Thin-walled aluminum rear axle.

Bottom Line:   
With less than 70 hours use, no air time, no abuse, no gnarly trails ... I broke the rear axle in half and broke 3 spokes on the front wheel. The spokes all broke under braking forces during descents. The rear axle appeared to be a cumulative fatigue fracture at the thread on the inside edge of the drive side cone. I've always found Shimano hubs to be among the most reliable in the industry, and its one reason I picked this wheelset over Mavic when shopping for UST racing wheels. I'm 190 lbs. so no lightweight, but not exactly a Clydesdale riding drops on these things. But now I'm stuck with a set of wheels which I can't even confidently race on. I also recently built up a wheelset on the 2008 XT hubs, which appear to use the same aluminum rear axle, so now I regret using those hubs and I'm worried I'll break the axle in a few months.

Submitted by Barry a Cross Country Rider from Vancouver

Date Reviewed: August 18, 2007

Strengths:    Light, stiff, accelerates like mad, red nipples

Weaknesses:    Freehub is prone to skipping with popping and crunching noises, and that goes for the warranty replacement freehub too.

Bottom Line:   
The wheels are incredibly stiff laterally for a wheelset under 1600gms, they accelerate like there's rockets in them.

After a couple of weeks of use the freehub started skipping after a brief bit of coasting over rough ground or after a slight back pedal. The first freehub would mostly just make the popping noise with no significant feedback at the pedals. The replacement freehub skips about 1/8 of a crank rotation when it makes the popping crunching noise. If you move the cassette/freehub by hand you can feel the point where the pawl just misses the rachet teeth and skips a tooth or two. So far it hasn't skipped under high loads like climbs, just after coasting or backpedaling.

Having run the XTR 960 hubs for almost 3 years with no hiccups of any sort in the freehub, it's disappointing to have problems with a new XTR wheelset this pricey.

According to the exploded parts diagram the freehub is the same on standard 970 series XTR hubs, it'd be interesting to know if anyone has seen similar problems in the freehub.

If the freehub was as dead reliable as my old XTR 960 hubs it would have been 5x5 review, but it gets a 3x4 instead.
