The three tubes form the main triangle of your mountain bike’s frame, being the top, down and seat tubes. Eventually, mechs get sufficiently worn that most of the cable pull just drags the slop out of the links rather than moving the cage sideways. Just like the frame, the most common material used to make wheel rims is aluminum. However, the size of the wheel has to be taken into account to determine how hard that gear actually is. Triples have been tweaked a few times with some interesting and odd combinations. The tire is connected to the wheel’s rim, which is the outer hoop of the wheel. The 32/16 combo will pedal pretty much the same as the 44/22 and 22/11. Gear cables run from those levers to their respective derailleur, transporting the message of what you’d like them to do. Interestingly, front derailleurs seem to work fine with any brand and any designated speed, but there is no doubt that matching for speeds across the parts results in less rubbing. Cassettes, Cogs & Freewheels. Why do we even need gears, and why so many? Shimano champion the triple configuration. Each gear shift results in a significant difference in pedaling power. Mountain Bike Components. It is interesting, though, to take a closer look at the different parts that make up a bike wheel. Often, mountain bikes with rear suspension have a much more complicated frame. The physical size of this has limited the size of the smallest cog to 11 teeth. The two wheels don’t need much explaining. The hub gear is an age-old solution that comprises of an enclosed planetary cog assembly inside the rear hub. The front derailleur works on a similar principle, with a linkage to shunt the chain back and forth, albeit this time without any tension duties to perform.

If the mech could jump say 20 teeth in one go you might find that the gear change is simply too much and you have to make numerous ‘recovery’ shifts at the rear to get the next gear you wanted. 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. Front mechs can only handle jumps of around 12-14 teeth in one gear change, and because of the angle the mech moves at, a minimum number is usually quoted too. The rear derailleur is much larger than the front one, hanging down from the center of the rear wheel. The total range of your gears is simply a comparison of the lowest ratio to the highest and is often expressed as a percentage. It wasn’t until 1982 that Shimano launched the iconic six-speed XT component group, and even this high-end equipment didn’t feature the basic stuff that we take for granted today, such as indexed shifting and slide on cassette sprockets. The brand of shifter has to match the rear derailleur. People have been riding singlespeed since the bike was invented and continue to do so for many reasons such as mechanical simplicity, low weight or just easy terrain that doesn’t demand so many cogs.

However, this is a much longer more detailed discussion when talking exact numbers because of different rear hub spacing (road, road disc, mountain, fat) and tire/chainstay clearance. It contains a spindle and the bearings that allow the cranks and spindle to spin. This allows us to compare gears across a wide range of wheel sizes, for example comparing an average 29er bike to an average 26in-wheeled bike, with exactly the same gearset, the 29er will feel about 10-11 percent harder to pedal. Are you an aspiring Red Bull-sponsored athlete? Below, we’ve compiled a comprehensive overview of every single piece that makes up a modern mountain bike. Quality frames will last years.

Similarly for the rear mech; most bolt on the same way but there are always exceptions. This is partly covered here for modern mountain bike spacing and here for fat bikes… You change the oil every so often and if anything goes wrong enough to need further intervention it’s time to seek out a specialist. Will the derailleur itself disappear at some point in the future?

The bicycle brake system consists of three main components. Here, too, the derailleur takes care of the shifting of the chain from one wheel to the other. Shifters: The shifters perform the magic, hauling a cable through the outers, eventually operating the derailleurs. Planetary drive gears aren’t just limited to the rear hub. If you must mix, try and mate the derailleur speed to that of the crankset. Tip 1: Start with the barrel adjuster to dial out any cable stretch, Tip 2: Light oil at the end of the housings will help ease cable drag, Tip 3: Check the cable for damage or fraying and replace if needed, Tip 4: The rear derailleur is the next place to look for grime, wear and tear – adjust where necessary, Tip 5: If you still can’t get a smooth shift, re-tension the cable and run through these tips again, Get £10 off the fantastic 1000W Cooks Professional Stand Mixer, Whip up some of your best bakes yet with this powerful and easy-to-use stand mixer.
