On the other hand, short cranks are better if you’re downhill mountain biking and go over lots of obstacles. Derailleur specifications can’t handle a sprocket larger than 36 teeth, which is why currently the widest ranging cassettes we see are the 11-36. Rear suspension is much more intricate and can be in either the stays or the seat tube. From derailleurs to valves, from brakes to pedals, you can find it all here. Wider ranging cassettes with more sprockets were introduced, not only to provide higher and lower gears, but to reduce the gap to the adjacent gear for more precise cadence control.

The three tubes form the main triangle of your mountain bike’s frame, being the top, down and seat tubes. Why not use a range like 6 to 42 teeth for a huge sequential range? Now while every mountain bike will have components 1 – 5, only some bikes will have a front derailleur (#6). Their price tags, however, can quickly climb into the thousands of dollars. A standard looking shifter and cable is used to shift the cogs about while a normal chainring and sprocket is utilised to drive the system.

Similarly almost all chains, regardless of designated speed, seem to work perfectly well on eight or nine-speed cassettes and chainsets despite slightly different dimensions. In total there may only be 13 or 14 unique ratios across the whole gearing range. They mount onto the freehub body of the wheel, and are locked down with a specific ring. Cassettes, Cogs & Freewheels. Already have an account with us? Handlebar Grips. With the advent of downhill at the end of the last century, and the introduction of all-mountain go-anywhere machines at the beginning of this one, manufacturers and riders soon realised a change in direction was needed. Triples have been tweaked a few times with some interesting and odd combinations. Some hub gears have already realised this, and no doubt we will see more planetary drives and gear boxes popping up over the next few years. These are located in specific places to allow the chain to climb and drop to the next gear smoothly and quickly. Trigger shifters with paddles are most common, but twist type and brake levers that double up as shift levers are available. Ibikeride.com says that disc brakes are good for all types of mountain biking because they offer consistent, effective braking regardless of temperature, rim condition, or trail conditions. None of this can happen without the shifters. Always ensure it is the correct length, and fit direction chains appropriately – wrap the chain around the largest cog and largest sprocket (bypassing the derailleurs), and add two links where they overlap. Similarly chains work best when in their own group, but using a higher speed chain on lower named cranksets works fine – though keep the chain matched to the sprockets for best results.

If you can’t get snappy shifting in both directions, something else is wrong. Front suspension is placed in the front fork. Below, we’ve compiled a comprehensive overview of every single piece that makes up a modern mountain bike.

The shorter the cranks, the less pedaling power you have. Shimano and SRAM have tweaked the cable pulls, so that 10-speed shifters must match their own 10-speed derailleurs. Again it comes down to technicalities involving the drivetrain equipment. TIP These bikes are also great for riders who have sore or damaged body parts … Reluctant downshifts (to larger sprockets) are often the result of cable stretch and can quickly be dialled out by turning the barrel adjuster on the mech or at the shifter.

Some systems, such as the Dynasys equipment from Shimano even have directional chains that take this concept a step further. Both mechs have two screws to limit the overall movement (preventing the chain derailing completely). Planetary drive gears aren’t just limited to the rear hub.

As well as moving the chain up and down the cassette in precise increments, it must also compensate for the change in chain length as we shift, and keep the chain under sufficient tension. By pairing the chainrings in a 3:2 ratio (42/28 and 39/26) with perfectly timed ramps and pins, SRAM have increased the front shifting speed and fluidity. By pulling the brake levers, the pads, one on each side of the wheel, get pushed together. Other parts like bottom brackets, pedals, headsets and derailleurs use … Gear systems and ranges have evolved over the years to reflect how we ride and the changes in the types of bikes on the market.

By entering your details, you are agreeing to BikeRadar terms and conditions and privacy policy. Each gear shift results in a significant difference in pedaling power. Front mechs are fully interchangeable though, except for a little rubbing with the narrower cages of the higher speed stuff on the lower equipment. Bearing: a device that facilitates rotation by reducing friction. The pedals are attached to the cranks, which are connected to the bottom bracket. Many modern mountain bikes come with either front or rear suspension, or both. Pedals and cranks may also be one of the parts of a mountain bike that are taken for granted.

The large touring-inspired triple chainsets that were standard on nearly all bikes were replaced with smaller, compact versions that provided greater clearance. The 32/16 combo will pedal pretty much the same as the 44/22 and 22/11. Multiplying the gear ratio by the wheel diameter gives us a number called the gear inch. Before that we relied on a simple friction system to adjust the derailleur action. The saddle is on top of the seat post. In many cases you can actually get away with going over the prescribed specs a little, but with so many combinations out there, always err on the side of caution and always ensure the chain is the correct length.
