A evaluate of Shimano’s 50mm laminated clinchers.
Shimano Dura Ace R9100 C60 Review
I wasn’t fairly positive the best way to assessment a wheelset and I’m definitely not going to make a behavior out of it. There’s solely a lot you’ll be able to say about their roundness.
Conversely, there’s in all probability tons lets say concerning the aeroness at numerous angles of yaw and at totally different speeds however then getting that info within the real-world ain’t really easy until you might have a wind tunnel mendacity round. Which I haven’t.
I might in all probability say a bit about weight too by copying the knowledge from the spec sheet. Yep. I ‘ll do that later.
‘Ride quality’ and ‘cornering ability’ are in all probability fruitful areas. However I assume I ought to have began out by cleansing it.
At the least you understand I’ve used it for greater than a photoshoot. That is about 50 miles value of Surrey mud and after a great hosing down.
These are the precise merchandise I’ve and which I shall be speaking about: WH-R9100-C60-CL-F (entrance) and WH-R9100-C60-CL-R (rear) which have been launched in 2016 pre-TdF.
Shimano might be greatest recognized for smaller mechanical elements of every type for all types of bikes. Maybe, in recent times, you’ll have come throughout their forays into electronics with Di2.
Dura Ace is the premium sub-brand of Shimano (Street). With Ultegra being the mid-range and Shimano 105 being the efficient entry-level for readers of this publish. I gained’t talk about the opposite street methods; Tiagra, Sora, Claris, Tourney, and so on..
There are two braking techniques on Dura Ace wheels: R9100 (rim) and R9170 (disc).
There are alternatives for tubular rim brakes (-TU), clinchers (-CL) or tubeless disk (-TL). These embrace full carbon rims and disk brake fashions.
C24, C40 and C60, kind of, refers back to the rim depth in mm. You’d be forgiven for considering that the C60 was 60mm. It’s 50mm for the CL model and 60mm for the others. Anyway, the bigger the C quantity the larger the rim.
The delicate variations and quite a few elements to the specification get difficult; there’s an abbreviated specification desk on the finish of this submit in addition to a hyperlink to the complete specs at Shimano if you wish to the minutae of bearing cups and butted spokes.
As to the longer term? This vary must be present till 2020/2021.
The R9100 C60 wheels at first appear comparable in specification to the R9000 C50 (from 2012).
Shimano’s press launch , at launch in 2016, claims the next
Two new 28mm extensive C60 and C40 rim platforms convey a stiffer wheel to reinforce ahead and side-to-side (lateral) energy switch and, with ultra-light carbon rim heights of 60mm and 40mm, are additionally designed to scale back air resistance. This enables Dura Ace R9100 C60 wheels, in an actual world state of affairs*, to save lots of 16W over Shimano’s present DURA-ACE 9000 C50 wheelset
In accordance with Shimano, the next power saving have been discovered within the circumstances of a cross wind at 7.5° on a 25c tyre when sprinting on a flat street: WH-9100 C60TU 1400g/set (16W saving) < New; WH-9100 C40TU 1331g/set (2W saving) < New; and WH-9000 C50 TU 1442g/set < Launched in 2012.
Thus, in case you are utilizing tubulars, then 16w is a notable improve.
Or you possibly can stick on an previous tyre like this and doubtless lose 16w !!
The Dura Ace R9100 C60 reviewed listed here are sweet-looking hoops. Of that there isn’t a doubt. I in all probability made a slight aesthetic mistake placing them onto an successfully all-black Cervelo body. The metallic rim stands out an excessive amount of (when clear ? ) and the all-black carbon rimmed ones would have seemed higher. My dangerous.
Though in the event you take a look at the DURA ACE writing on the rim you will notice it’s ‘stealth black’ or ‘shadow black. I think this gives the rim the look of near-complete blackness and hence the metallic rim stands out more. Compare that to other wheels, like my Mavic Cosmic Carbone, and they have bold white branded lettering and hence that somewhat detracts from the metallic rim.
Like you I have other frames and the Dura Ace wheelset probably looks better on those other frames. If I get some of my red Schwalbe tyres out of their boxes and onto the bike then, no doubt, those tyres will throw the overall bike aesthetics into the long grass. Never to be discussed again.
I’ve learn a couple of feedback concerning the aesthetics of the hub and spoke element elsewhere. The hubs look fairly strong to me, the freehub is titanium people; that ought to go well with you properly when your watts hit the four figures;-) The hub is just not the type of factor I take a look at.
I fairly just like the straight bladed spokes. I’ve seen requires the return of the J-spokes…I imply, that basically doesn’t have an effect on my enjoyment of the journey.
The rear takes 10/11 velocity Shimano rear cassettes.
They take ‘normal’ tyres. Regular sized clinchers. They want an inside tube.
You’ll want an inside tube with an extended than regular valve. I have a tendency to make use of 80mm. Though I feel the image additional under exhibits a 60mm one.
The Dura Ace R9100 C60 reviewed listed here are primarily a alternative for my cracked up Cosmic Carbone SL wheels from someplace round 2012. The Cosmics appeared to be one of many Age Group triathletes’ wheels of selection again within the day. The R9100 matches the identical biking area of interest because the Cosmics, I don’t see them as an improve as such.
The R9100s in all probability are a bit stiffer, perhaps a bit extra aero and positively so much quieter than the Cosmics which have the rim coming unfastened someplace ! Positive I can raise the bike up and spin the R9100 entrance wheel and it spins for longer than the Cosmic…perhaps I give it a much bigger push or perhaps the bearings are simply newer ?
I’m an inexpensive bike owner and I do parks and hills (Surrey) moderately than mountains. So for the type of speeds I’m going and the type of terrain I’m going on, I see this Dura Ace wheelset as a ‘performance all-rounder‘ ie I’ll use them 70-80% of the time when outdoor. 90spi? Yep that ought to do properly more often than not too.
- I’m not going to make use of them on a TT.
- I’d use them on a windier race day rather than a rear disk and 60mm entrance rims.
- In France later this yr I’m going to be doing a number of 2000m vertical days, so it’s 50:50 whether or not I take these or scrounge some critical mountain package from associates
- You’ll in all probability discover that at most individuals’s biking degree, that the aero impact of the wheel will prevent greater than a lighter, minimally rimmed wheel. Simply sayin’.
I like the normal aluminium rims. Extra particularly, I just like the predictability of the braking.
I’ve had a couple of feedback over current months with these wheels and through the years with the Cosmics and concerning the 50mm rims generally. “Isn’t it too windy for them?“. I generally never worry about winds up to 15mph and above that I’m often to wimpy to go out anyway ? The only issues, I find, are in gustier conditions where the higher winds can unexpectedly take the front wheel away slightly. Hey! Just go faster. Force vectors and all that.
I have no problems recommending this Dura Ace wheelset for the type of usage I’ve described. Are there cheaper and better options from brands you have not really heard of? Maybe. Do Waitrose beans taste better than Heinz beans? Errr. With Dura Ace you have a certain expectation of high-end performance. Well, at least I do.
I find it pretty hard to have niggles with wheels. My only issue was as follows.
Each wheel comes with a tiny circular, rubbery sticker that has a hole it goes around the valve from the inner tube, adhering to the outer rim. I think this sticker both stops the valve banging on to the rim (?) and helps keeps dust/water out of the rim innards. Bottom line: I couldn’t get it to stick down. And I was never sure either what would happen when it came to changing the inner tube in anger…surely it would come off then too?
Wheel size is 622x17C with recommended tyres sizes of 23-622 to 32-622
The C60 clinchers are 50mm deep. The rim width is 22.4mm front and rear. There are 16 spokes on the front and 21 spokes on the rear.
Specified weight is 832g (front) and 1019g (rear) giving an overall weight of 1,851g.
They are available now…and have been for a while! You will probably save money buying a complete set. You may well be able to get these cheaper at your LBS, especially if they have some sort of loyalty scheme like Sigma Sport (my LBS). Wiggle and Chain Reaction are also obvious places to look.
