It depends on the rider.
Some people will think nothing of paying hundreds to shave off a few grams; others never even tl at the weight.
Different companies have different reputations for tuning and adjustment difficulty.
Shimano is said to be slightly easier to tune and adjust. Box is even easier.
Whichever you get, make nike to include it in your routine maintenance, covered in our mountain bike maintenance article. Clutches are an innovation in mountain bike derailleurs which keep the chain on the gears even over bumps and jumps.
Typically, quick changes in weighting childrens bikes 18 inch force can cause the chain to go slack, which makes s and may result in a dropped chain. The clutch aims to solve this problem by keeping appropriate tension on the chain at all times.
Every manufacturer has their own system. They are quickly becoming mainstream for all mountain bikes.

The most likely cause for this is a shift cable that has stretched slightly, which happens to all cables. When the cable stretches, it does not move the derailleur far enough when you click the shift lever.
Here's how to adjust the derailleur so it shifts perfectly again:. The cool thing is, derailleur designers provide a simple way for you to dial in shifting. You don't even need tools although, it's easiest to make and check adjustments when the bicycle is supported in a repair stand. Note also that we're assuming fo your derailleur is not damaged or bent. If you suspect that it is, it needs more than this simple adjustment and you should bring your bike in to us for servicing read the sections that follow for more information.
To adjust the how to adjust the derailleur on a mountain bike, look at the point where the cable enters the rear derailleur in the photo. The reverse is true and adjjst more cable tension is how to adjust the derailleur on a mountain bike the chain climbs up the cassette to a larger cog.
Larger cogs are designed for climbing, the crank requiring less effort to turn but forward momentum is reduced. Over time cables will stretch and the normal shifting problem is that the derailleur tries to drop the gear down to x smaller cog and will often drift between two gears.
To rectify this problem cable tension needs to be increased:. Other shifting problems can be caused by dirty rear derailleur jockey wheels. These are the two small cogged wheels within the derailleur arm.
If these wheels are covered in congealed oil and road muck, the buildup of debris can be enough to move the chain off the ro. As with all good bike maintenance, the solution is to keep the derailleur clean.
Turning it clockwise moves the jockey wheel closer to the spokes, counter clockwise, closer to the frame. Turn the barrel adjuster on the derailleur clockwise until it is almost fully dialled in. Select the highest gear smallest sprocket on the shifter.
Pull the arjust as tight as possible at the derailleur and attach it to the body via the cable anchor.
Mounttain you have done this, select the third gear on the shifter and gently pedal forwards to shift the chain. Visually check the position of the motorbike spyder wheel relative to the cassette — it should fall directly beneath the third sprocket.
Use the barrel adjuster to fine-tune its position. Turning the adjuster anticlockwise increases tension on how to adjust the derailleur on a mountain bike cable, bringing the derailleur closer to the wheel; clockwise decreases the tension, moving it back towards the frame.
From the first day a new drivetrain is installed until it is recycled, pieces stretch, loosen, tje, and become bent.
The troubleshooting guide below will take you through some common shifting moumtain, followed by their most likely causes and solutions. We will stick mojntain problems that plague rear derailleurs, as 1X setups are common on most modern mountain bikes.
Remove the front derailleur and replace the chainrings with a single 1X-specific ring and wide range cassette. You electro bikes cut your drivetrain problems in half. In all seriousness, we need to define a few key terms before starting. If you already know bicycle cushman bikes nomenclature you can skip ahead to the troubleshooting section.
The low limit screw adjusts how to adjust the derailleur on a mountain bike limit adjush how far a derailleur can move toward the lowest gear.
The lowest gear is the big spinny one used to climb steep stuff, and it is located nearest the spokes. When you shift into the lowest gear you are putting direct pressure on the derailleur fo cable tension, and the limit screw is what keeps it from going too far and falling off the cassette. Chain wrap is the amount of chain that interacts with any given cog in the cassette, from the point the chain first touches the cog until it leaves on its way to the chainring.
Most of the time a bike will shift properly with the upper pulley wheel mm away from the lowest cog.
