Today we are featuring product Mavic Crossmax SLR 27.5 Disc Wheelset, a great example of one of our Bicycle Wheels from Mavic. We give it 3.5 out of 5 stars.

Mavic Crossmax SLR 27.5 Disc Wheelset

Lithe and lightning fast, the Mavic Crossmax SLR 27.5 Disc Mountain Bike Wheelset is built to meet the demands of cross-country racing. Proprietary lightweight aluminum rims have a drilling method that doesn’t penetrate the tube-facing wall, enhancing wheel strength and rigidity. This drilling method also allows UST tubeless compatibility, offering all the benefits of tubeless with the option of using a traditional tube/tire setup. Inter Spoke Milling 3D dramatically reduces material between spokes and along sides of rims, reducing weight and making them well-suited to climbing and fast acceleration. Rim joints are welded and milled to maximize strength, rigidity and wheel balance while also offering a smooth finish. Rear hub uses Instant Transfer System 4 freewheel design to supply fast engagement via 4 pawls, ensuring your energy is transferred to the wheel quickly and efficiently. Double-sealed cartridge bearings deliver excellent longevity and smooth spinning; microadjustability lets you fine-tune bearing loads to optimize your ride. Both wheels use 20 lightweight, straight-pull and bladed Zicral alloy spokes; front is laced 2-cross while rear uses radial lacing on drive-side and 2-cross on non-drive-side. Front hub is compatible with either 15mm thru-axle or traditional 9mm quick-release; rear hub is compatible with 9mm or 12mm axles, 135mm or 142mm axle widths. Mavic Crossmax SLR 27.5 Disc Wheelset is compatible with standard 6-bolt disc brake rotors. Comes with wheel bags, quick-release (QR) skewers, front and rear QR adapters, rear 12x142mm adapters, removable UST valves/accessories, magnet, adjustment tool and disc bolts. Mavic recommended maximum combined weight of the cyclist, bike and equipment is 220 lbs. (100kg); recommended tire width is 1.5 – 2.3 in.

    Why Don’t Bicycle Wheels Buckle? Bicycle spokes are easily bent. When you sit on a bicycle, how come the wheels don’t collapse?

    View Comment
    1. Reply

      Bicycle spokes may be easily bent if put under a bending load or will buckle if put under compression, but they don’t stretch when put under tension. The rim is also fairly weak without the spokes and can be pushed or stretched out of round, but it still has some stiffness and its circumference won’t easily change if it is distorted in this way.

      When you sit on a bicycle, the hub tends to be pulled toward the ground. The spokes above the hub are under tension, transmitting the force to the top of the wheel rim. This would make the wheel rim collapse into an oval if it could do so without the sides of the rim to the front and rear of the bicycle sagging outward in the process. However, the spokes going to the forward and rear part of the wheel rim prevent the rim from going pear-shaped in this way.

      The spokes are also not fastened to the center of the hub but to either side. This prevents the hub from deflecting sideways because half the spokes will be under greater tension if the hub tries to deflect in that way.

      Finally, the rim cannot rotate with respect to the hub because the spokes don’t run exactly radially from the hub to the outer rim. Instead, the hub flange is comparatively wide so that half the spokes are under tension if the rim tries to rotate forward with respect to the hub and the other half are under tension if it tries to rotate backward. Either way, the rim is not free to rotate.

    Physics Bicycle Wheel? You are trying to raise a bicycle wheel of mass m and radius R up over a curb of height h. To do this, you apply a horizontal force F.

    a) What is the least magnitude of the force F that will succeed in raising the wheel onto the curb when the force is applied at the center of the wheel?
    b) What is the least magnitude of the force F that will succeed in raising the wheel onto the curb when the force is applied at the top of the wheel?
    c) In which case is less force required, the first (a) or the second (b)?

      A) Both applied force F and weight W exert opposing torques, both pivoting in the point where the wheel touches the edge of the curb. Briefly stated, force F will succeed to lift the wheel if its associated torque is greater than the torque due to weight. In mathematical terms,

      L = r x F + r x W.

      All terms in the equation above are vectors. L is the resulting torque; r x F is considered positive. F will lift the wheel whenever L > 0.

      As much can be said without resorting to a figure. Please follow these directions:
      1. Draw a circle.
      2. Draw a cross-sectional view of the curb, on the right side of wheel. Curb height h should be smaller than wheel radius r.
      3. Draw a line from the center of circle to the point where the circle touches curb edge. Label this line “r”.
      4. Both F and W are supposed to act on the center of the circle. You may tentalively draw both, F as a horizontal line, directed to the right; W pointing down from the center.

      A solution can be found either following a geometrical approach (in terms of r and h), or else by trigonometrical means (in terms of the angle between r and the horizontal -or vertical. Much more often than not, those who post Physics problems in Y!A know the answer beforehand. I have no way to know if the answer you got -I’m sure you do- is in a trigonometrical, rather than geometrical, format. However, since h is mentioned in the problem statement, the latter alternative seems to me more likely.

      Since F and W are perpendicular, one horizontal and the other vertical, resolve r into its horizontal and vertical components. These will be the effective “lever-arm” for each of theseforces. The vertical component is readily found in terms of r and h: it is just (r – h). The horizontal component can be found by Pythagoras’ Theorem. We have (in scalar format):

      L = F(r – h) – W ?[r? – (r – h)?]

      Minimum value for F can be found letting L = 0 and solving for F. The resulting algebraic expression is too cumbersome to be included here, and I think it is hardly necessary to do so. Besides, there are several algebraic manipulations possible. Likely, I would end with a different -albeit equivalent- expression.

      b) When F is applied to the top of the wheel, the effective lever-arm for F increases to 2r – h. Refer to figure, or, rather, draw a new one. Join the uppermost point on the wheel to the contact point between wheel and curb edge. Now, persuade yourself that the vertical component of this line equals wheel diameter – curb height, or 2r – h.

      Torque due to W remains as before. Consequently,

      F(2r – h) = W ?[r? – (r – h)?].

      Least F is found solving for F.

      c) Clearly, with increased leverage, it would be easier to lift the wheel onto the curb in the second case. This is not apparent from the formulas, however.

      For this purpose, the solution in trigonometric form offers much better insight. Here they are:

      1st case: F = W / tan ?, where ? is the (clockwise) angle r makes with the horizontal.
      2nd case: F = W cos ? /(1 + sin ?)

      Note that for ? < 45?, F > W, in the first case. Also, F = W if ? = 45?, and F < W if ? > 45?. On the other hand, in the second case F < W is always met, since both sin ? and cos ? lie in the range 0 to 1. Thus, the numerator will be typically < 1, while the denominator is guaranteed to be > 1. The resulting fraction will in every case be less than unity.

    Diameter Of One Bicycle Wheel Is 28 Inches And Its Spoke? Diameter of one bicycle wheel is 28 inches and its spokes run from the hub (or center) to the edge of the rim. The diameter of another bicycle wheel 21 inches. What is the difference in inches between the length of the spokes of the two wheels?

      There are many more complexities to a question like this. Do the spokes truly radial to the hub and rim or do the cross over the other spokes? How many times do the spokes cross over other spokes?

      28″ and 21″ are likely the relational size at the tire bead. What are the actual inside diameters of each rim?

      What is the diameter of each hub? The spokes don’t originate from the axle but from a flange on the hub which is of some diameter. Each make and model of hub is slightly different and will differ between front and rear hubs and can even differ from the left to right flange on the same hub.

      What is the distance from the left flange to the right flange on each hub and what is their relation to the center of the axle and to the center of the dish of the wheel? Is it a front wheel or a rear wheel? Is it a disc-brake equipped hub?

      Now that you know a little more about the complexities of spoke lengths and wheel sizes, perhaps you should do your geometry homework yourself. If you are truly building wheels and want to know the spoke length differences, I suggest you read some articles that Sheldon Brown wrote.

      Good luck!

    A Smaller Bicycle Wheel? I am in the process of researching the creating and specs of a bicycle to create a more minimalistic cycle. Can anyone tell me how the size of the size of the wheel affects the ease of use and other things. It would be much easier on the creation process if i could slim down the wheels alot
    I am in the process of making a bike that is its own bike rack in the sense that it fits into a brief case once folded. I have basic sketchs down and such but the wheels are still a problem for me due to their size. I have done some exploring and find a bike that is close to the concept im looking for but far from the look. Its called the Strida. It features a smaller wheel diameter and folds very compactly but if quite ugly and looks far from a bike.

    What i am making can be called a “commuter bike” made for a person like me that lives far from college and rides a bike around campus but has a problem with putting a bike on a rack.

    hope this helps and wasn’t to a.d.d. and all over the place

      Well I can tell you about using smaller wheels because I use smaller wheels on my rides, I use the 16x 1(19-349) size and a 20x 1(19-451) at 120psi and I also use the standard 20 x 406 tires at 100psi. All the wheels are highly responsive, fast and ride equally as well and all use the standard bicycle components, gears, shifters etc. The thing about using smaller wheels is that everything you do such as turns, braking, shifting all seem to happen at a accelerated or faster rate so I’d take that into consideration. The other thing you may want to consider in using smaller type wheels in your bicycle would be chain-rings. Smaller wheels have a disadvantage when climbing so I’d go to a triple crank set, it should give you back some gear ratios you may need.
      Some one also mentioned that smaller wheels would not be as fast or harder to ride, I have to disagree. If the bike is set up right it can be faster with less effort. Just change the crank-arms out from the standard crank-arm length of 172.5 to a smaller crank-arm say a 165 that’s the size I run and increase your large chain-ring from a 53 tooth to a 61 or 64 tooth with a 11-32 tooth rear cassette you can have all the speed with less effort you want. I hope some of this helps you out and Good luck with your creation, lets us know how it works out.

    Where Can I Find Bicycle Wheels To Buy Online? Moreso what i’m trying to figure out is if i can replace the back wheel on my bike i’ve bought from Wal Mart. It’s a Mongoose XR-75 26″ Mens mountain bike. Everytime I try to find wheels all i get is more bikes brought up, and i’d like to just buy a new wheel.

    I seem to have bad luck with the back wheels on my bikes. First one i had the cart pushers at wal mart bent the wheel to hell. Second the axle snapped. And this one i went off a curb and landed on the exact wrong area to land, the road was raised higher then the gutter area by a good two inches and I landed right on the corner of it, doing so put a pretty good bend in my wheel. I know I should be more careful but they’re generally cheap bikes, so it’s not too big a problem, I just would like to see if I could buy a new wheel rather than a new bike. : /

      Google “bicycle wheel sets”, you’ll be able to search for new wheels from there. the problem you will have online is most wheel sets will have 9 or 10 speed cassettes. my guess is yours is a 7 speed cassette. also, most rear wheels will cast close to the original cost of this bike! since you seem to enjoy riding a bit aggresively, STOP WASTING YOUR MONEY! start saving for a properly fitted bike at your LBS! a solid entry-level hardtail MTB (a dual suspension bike that’ll take your brand of abuse will cost more than $1000) for $300-$500. by the time you add up what you’ve spent on repairing your wallywood bike, you’ll be well into that number anyway. good luck either way!

    Best Road Bicycle Wheel Set For The Money? My buddy and I just started biking and we are getting faster each week but not fast yet by any means. Our question is what wheel set would be worth the money. We heard of Hed 3, Zipp, Mavics, etc… Would love opinions. How much speed per mile could be gained with one of the good wheel sets compared to wheels that are ok that came with bike. Thanks

      There are all sorts of wheels and they would provide different advantages and disadvantages for different types of riding. For example, severely aerodynamic rims are faster but more prone to crosswinds and, being stiffer are not as desirable for long distance.

      You need to consider weight, durability, aerodynamic resistance, type of tire you will be using (clincher or sewup), numeber/type of spokes, spoke pattern, rim and spoke material, etc.

      I don’t want to recommend a specific brand/model, but in general aim for aluminum alloy rims, stainless steel spokes and quality hubs. While the nicest wheels to ride are light weight (minimizing rotating weight is ALLWAYS desirable, for everyday use you will probably be best to avoid really lightweight wheels because you sacrifice durability. Similalry, while a more aerodynamic cross-section rim is faster you don’t want extremes for reasons given above. Wheels with few bladed spokes (16-20 in the front wheel, 20-24 in the rear) are a bit faster.

      I recently bought a bike and upgraded the stock wheels for the next model up because they were about 150 gms lighter for a pair. because of the alloys and design the lighter wheels are just as strong or stronger … but cost a couple of hundred dollars more. See how a little weight saved can cost a lot?

      If you want speed for the flats or mild hills go with aero wheels, but frankly the difference will be most noticable with bladed/fewer spokes and lighter weight relative to your current wheels.

      One hint .. read reviews then look for used wheels. The links are to just one manufacturer’s lineup of wheels and to a good classified site for used bikes and equipment.

      I have only general knowlege about 3D graphics, but perhaps I can help. You need to simplify it – stop looking at the treees, look at the forest. A typical bicycle wheel isn’t that complicated. You have the hub and the rim. The spokes all come from the center line on the hub. On the rim there’s two “equatorial ” lines. One is roughly 1/3 in from the left side, and the other is the same from the right side. Half of the spokes go from the hub to each of those lines, so when you look one is “in” and one is “out”. Make a spoke from the hub to an outer line, and then sweep it some number and the spokes will go in place around the circle. Do the same on the other side of the wheel, in an alternating spot, and you’re done. Can’t tell you exactly which buttons to push in Pro-E, though I’ve played around with it a bit.

      Saw a bicycle on the train this morning and saw that I got it backwards (not a biker). The wheel spokes go in the center and they alternate on the hub. Just thought I’d fess up to a mistake.
