The position of shock mounts is only one variable of many of the rear linkage design. It does not play an isolated role but really is tied to everything else.
You might have missed that there are many other designs. The upper mount can be on the top tube as well:
Or really, in many other places, like in-line with the seatstays:
Or pretty much hidden just ...

Manufacturers design the bike suspension with specific characteristics in mind. For example, should the bike be more poppy or plusher and ground hugging to ride. One parameter in this process is the leverage ratio curve of the rear wheel (Wheel Travel/ Shock travel over the whole travel range). There are many more parameters, but I won't go into details, ...

I think you are referring to an end cap. On some hubs, you can actually change out the end caps to accommodate either quick releases or thru axles (and for those, you can get end caps for 15mm or 12mm axles). Many older hubs don't have end caps, but many current generation disc hubs do, because road bikes sometimes don't use 12mm front and rear axles. Hence, ...

Assuming the new rim is about the same width as the bent one, then the tyre and tube should transfer over okay.
You need to check the valve hole in the rim - there are two common sizes, and the wrong one won't fit or risks punctures at the base of the valve.
I suggest you fit the tyre, and inflate it to a relatively high pressure, whatever's maximum on the ...

From the WTB Website:
GMS Global Measuring System The current industry standard for specifying the actual inflated size of a bicycle tire does not account for subtle variation in tread and casing size. To address this problem and provide you with more information for comparing tires, WTB has introduced the Global Measuring System (GMS) for tire measurement.

Generally speaking, no.
A liquid-fuel engine wants to turn a lot faster than a cyclist would turn the cranks. That's why a retrofit engine often has a small drive cog and an enormous cog on the rear wheel, to decrease the revs and increase the effective torque.
The optimal speed of a small capacity liquid engine is somewhere between 1000 and 2500 RPM. A ...

A lot of forks do this because the axle path is wrong. It needs to open forward to resist ejection force by disc brakes. The downward path was chosen to do the same for rim brakes. Many companies have made this switch, but not enough.
High-quality internal-cam QRs apply the most clamping force of any type. The simple answer is get any Shimano skewer. A ...

You have the normal standard omnipresent pedal type with a 9/16 inch thread. If the size is not specifically indicated, it almost certainly fits. You canfirm it by some crude measurement.
The manufacturer speaks about a 7 mm boron steel axle, but that is hidden inside, it is not the thread diameter.
The number on your pedal might be a date of manufacture or ...

If it's only 6 months old, take it back to the shop as it wasn't fit for sale.

All suspension designs all aim to achieve the greatest pedaling efficiency whilst providing the best dampening of ground irregularities.
In an ideal world you want to enjoy the ride up as well as the ride down. Meaning you want your bike to pedal well uphill and be stable and smooth downhill.
Sadly, you can only have either of these qualities as designs are ...

I have tried the helmet mounted mirror and found it just too hard to use. It just took forever to get focused and see anything. Also, I feared stabbing myself in the eye if I fell.
I now have and love my drop handlebar-mounted mirror. so easy to use. I have the C&C ultralite, which is made in Germany and has been for at least 20 years.
It is on the ...

We can't give valuations - that's considered off-topic because they're highly region-specific, and go out of date fast.
The bike you're looking at is available here-and-now, and the seller is asking a token sum. In these days of C19 and shaky supply lines, any bike is better than no bike.
If you need a bicycle, and this one fits your body, you find it ...

Information about fork travel should be present in marketing materials to a bicycle. If you are looking at a web shop page, such information is usually hidden somewhere in the lower part of a page.
Alternatively, the travel is usually specified somewhere on the fork itself. If you could see the bicycle in person or ask the seller, that would be the most ...

The NX chain is of slightly higher quality, so it will last longer and shift better. That's not relevant here though.
Yes, you need to shorten a new chain in most cases. The riveted pins increase the chain's strength, but do require a decent chain tool to punch out. Hold the new chain up beside the old chain, matching link to link, and break it at the same ...

There are many brands and types of cranksets you could mount on to the Rockhopper frame, even the newer style, 2 piece cranks that require external bottom brackets, where the cups and their bearings remain outside the bottom bracket shell of the frame. Their is little to worry about as far as compatibility as the same bottom bracket is used for 68 or 73mm ...

Stout is a captive brand for Specialized, so if you want an identical replacement, the first place I'd go is to the Specialized dealer who sold you the bike. They should be able to source replacement parts. If you didn't buy it new, just find a Specialized dealer near you.
Alternatively, you can look online for a matching crank. The ones you'll find for sale ...

Hmm... 1x drivetrains will put the chain in extreme lateral angles, so back-pedaling issues are common.
But you know your bike and you seem to indicate that you did not have back-pedaling issues before.
So I would start troubleshooting by ensuring that your derailleur hanger is not bent - there are tools to gauge and align the derailleur hanger.
Also, check ...

As correctly stated by @ Renaud, your derailleur has a max rear cog of 36 teeth. In practice, however, it can handle larger cogs in most situations with 42 teeth likely being the absolute most it can handle. The issue is getting enough space between the upper jockey wheel of the derailleur and the largest cogs so that the derailleur's jockey wheel doesn't ...

The RD-M786-SGS is rated for a big sprocket of max 36T, so if you want to follow strictly Shimano specs, no.
That being said, Shimano has high standards and is very conservative, so it is possible that it works. I personally just installed on my bike a Microshift 9sp 11-42T cassette (no goatlink) on an Acera RD-M3000, rated for 36T max (I had to adjust the B-...

It sounds like you're asking if you can put a mountain bike tire directly over the wheel + tire of a road bike.
(please correct me if I am wrong)
There are a few things to account for.
It is not very safe to put a tire over another tire, as most tires are slick and the inner tire may not gain traction on the inner tire.
It is not likely that the mountain ...

Try taking all the air out so you can feel just the damper’s resistance. Low speed compression will be noticeable when doing body movements such as preloading, weight shifting, or braking. High speed compression is for events such as hitting big drops and large square edge impacts. The easiest way to test that is to smash into a square curb (perhaps with a ...

Yes, it is worthwhile. See it this way: for 10 pounds/eur/usd you will commit yourself to rebuild a bicycle starting from a decent steel frame, plus you will have a deep understanding of the value of bicycle parts.
Years ago I bought a steel frame (Trek 750) for 10Euro (with fork), for 10Euro I bought a fitting rear wheel with 9 gears ... then I brought it ...

Concerning the bike design, it's a machine that has to meet different design targets. There are
purely technical optimizations, which lead to designs that are very specific for the use case: like downhill vs XC, .. more allround or maybe even very specialized like dirtbikes or trialbikes. Usually there are also other constraints that play a significant role....

I've had a revelation using compressionless cable housing with my mechanical disc brakes, even with road bike levers they offer superb stopping power with little to no "sponginess". I'm using Jagwire myself. I would suggest replacing the wires at the same time.
Two more things which I don't think were mentioned: aside from cleaning the rotors with ...

The chromed crown in your photo doesn't have the prominent M-shaped lip, the diamond-shape in the middle looks more like the Marathon range.
