High-pivot mountain bikes have enjoyed a resurgence in recent years, with big-ticket launches from brands including Forbidden, Cannondale, GT, Deviate, Devinci and Norco all adopting an idler and coming with claims of improved suspension performance.<\/p>\n

A high-pivot suspension design raises the bike\u2019s main pivot well above the top of the chainring and rear wheel axle, with an idler then used to reduce chain growth and pedal kickback.<\/p>\n

In turn, by creating a more\u00a0rearward axle path\u00a0as the suspension compresses, high-pivot mountain bikes are said to offer\u00a0plush-feeling suspension with impressive grip on rough terrain and technical descents.<\/p>\n

Are high-pivot bikes worth the hype? Let\u2019s delve into the origin of high-pivot suspension, how it works, the pros and cons, and whether a high-pivot bike is right for you.<\/p>\n

A short history lesson<\/h2>\n

Mountain bikes have developed exponentially since their inception and these changes, from the advent of 1x drivetrains and shifts in wheel size<\/a>, to progressive geometry and emerging sub-genres such as downcountry<\/a>, have accelerated in the last decade or so.<\/p>\n

Manufacturers have also experimented continuously with mountain bike suspension designs to improve performance and overall ride quality.<\/p>\n

By and large, conventional suspension types include single-pivot, twin-link and Horst-link designs, and many bicycle brands then have their own take on the recipe, such as Santa Cruz\u2019s VPP or Yeti\u2019s Switch Infinity and Sixfinity systems.<\/p>\n

High-pivot designs originally started to emerge on downhill machines in the early-2000s, with iconic bikes from Balfa and Brooklyn Machine Works<\/a> cementing the system\u2019s importance. Trek was then among the brands to take high-pivot into the mainstream with the launch of the 2006 Session<\/a>.<\/p>\n

In truth, high-pivot never went away, but while the system was, and still is, used primarily on downhill bikes<\/a>, a number of brands are starting to introduce high-pivot designs on their shorter-travel all-mountain and enduro bikes<\/a>, including the Norco Range<\/a>, Cannondale Jekyll<\/a> and GT Force<\/a>.<\/p>\n

The resurgence can be attributed partly to the adoption of 1x drivetrains, which started with the launch of SRAM XX1 in 2011<\/a>. Now, manufacturers don\u2019t have to take the front derailleur into consideration with the pivot design and layout.<\/p>\n

However, don\u2019t overlook the desire of brands to continuously develop and iterate. We\u2019re at a point in time when almost all other aspects of mountain bike design are finely tuned, so brands are looking for the next talking point or \u2018marginal gain\u2019.<\/p>\n

If you\u2019re in the market for a new trail, all-mountain, enduro or downhill mountain bike, high-pivot is now a viable consideration.<\/p>\n

All full-suspension mountain bikes feature some permutation of pivot or linkage that connects the front and rear triangles together (before we get any further, you can also read our complete guide to rear-suspension designs<\/a> for more).<\/p>\n

The pivot or linkage allows the rear triangle (also known as a swingarm) to rotate around this pivot point, compressing the shock as it cycles through its suspension travel<\/a>.<\/p>\n

Because the rear wheel is attached to the swingarm, when the suspension compresses it allows the wheel to move in a predetermined trajectory, known as its axle path. This wheel movement is how the bike absorbs bumps and shocks, providing grip and making the ride smoother.<\/p>\n

Pivot placement location \u2013 whether that\u2019s low, mid or high, or if the bike uses a multi-link suspension design \u2013 dictates the axle path of the rear wheel.<\/p>\n

The bike\u2019s main pivot (or \u2018instant centre\u2019 on virtual pivot-point, twin-link, four-bar or six-bar suspension designs) must be placed much higher than the bike\u2019s rear wheel axle in order for the axle path to be rearward, and the higher the pivot, the more rearward the axle moves.<\/p>\n

If it is too close to or lower than the wheel\u2019s axle, the bike\u2019s axle path will be vertical or forwards.<\/p>\n

In simple terms, a high-pivot mountain bike\u2019s pivot is moved further upwards, significantly above the top of the chainring. This creates a more rearward axle path as the suspension compresses.<\/p>\n

The images below show the exaggerated rear wheel axle paths of low-pivot, mid-pivot and high-pivot suspension designs.<\/p>\n

As a high pivot\u2019s rear suspension compresses and the wheel moves up and rearward along its arcing path, the bike\u2019s effective chainstay length (the distance between the centre of the bottom bracket and centre of the rear wheel\u2019s axle) grows.<\/p>\n

This, in turn, results in both upper and lower chainline growth \u2013 the lengthening of the distance between the centre of the rear wheel axle and the bottom bracket<\/a>.<\/p>\n

Lower growth is compensated by the rear derailleur<\/a> cage moving forward when the suspension is compressed.<\/p>\n

Upper chainline growth, on the other hand, causes pedal kickback. Because the cassette<\/a> and chainring move away from each other when the rear wheel is moving backwards, the cranks are \u2018pulled\u2019 back as the suspension compresses.<\/p>\n

Although pedal kickback can be disconcerting for some riders on the trail, others like the feeling because it can be used to generate speed through pumping. That said, it depends on exactly how much pedal kickback is produced and this is where the idler comes in.<\/p>\n

Introducing the idler pulley\u2026<\/h3>\n

If a traditional drivetrain setup were used, pedal kickback and pedal bob, where the bike\u2019s suspension dips in and out of its travel as a rider pedals, would be a significant problem on high-pivot bikes.<\/p>\n

Manufacturers get around this issue by utilising an idler pulley \u2013 or wheel \u2013 that routes the bike\u2019s chain near or concentric to the main high-pivot location. This looks very different from a conventional system.<\/p>\n

Placed correctly, the idler should reduce the chain growth and pedal kickback that would otherwise result from the high-pivot design.<\/p>\n

What are the benefits of a high-pivot mountain bike?<\/h2>\n
\""The\"<\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/picture><\/div>

High-pivot mountain bikes have a number of purported benefits, particularly when it comes to more aggressive riding.<\/p>\n

Improved suspension control<\/h4>\n

As we\u2019ve already covered, the main benefit of a high-pivot system is the more rearward axle path as the suspension compresses. This translates into a smoother, grip-abundant and planted feel on descents and climbs.<\/p>\n

In terms of trail feel, the more rearward axle path, combined with the idler pulley, results in increased stability and control.<\/p>\n

High-pivot suspension systems feel supple and are able to soak up rough terrain with greater precision and ease. This makes the bike easier to ride faster because its suspension is working harder to iron out bumps, reducing how much work a rider needs to do.<\/p>\n

Generally, they\u2019re also more forgiving. If a rider gets off-line or makes a mistake, the active and absorbing suspension compensates for the error, helping maintain control and speed.<\/p>\n

Pedal kickback and anti-squat can be tuned<\/h4>\n

From a technical perspective, pedal kickback can be tuned, along with the bike\u2019s anti-squat (how much the suspension resists pedals bob), by the placement of the idler wheel, chainring and pivot.<\/p>\n

Depending on how the bike is designed, the way it rides can be altered significantly, and the chainring size can also be changed without affecting either the anti-squat or pedal kickback.<\/p>\n

All of these benefits ultimately suggest a greater suitability towards longer-travel genres such as trail and, in particular, enduro and downhill, where supple and active suspension will be of most benefit.<\/p>\n

What are the disadvantages of a high-pivot mountain bike?<\/h2>\n
\""High-pivot\"<\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/picture><\/div>

So far, so good, but there are, as you\u2019d expect, some disadvantages to consider.<\/p>\n

Increased maintenance<\/h4>\n

Most high-pivot setups will require a longer chain due to the extended routing required, and therefore a more spendy outlay when it comes to replacement.<\/p>\n

Sticking with the theme of maintenance, the idler pulley is another component that will wear through use, and you\u2019ll need to factor in replacing that, too.<\/p>\n

An idler may also be harder to source because they\u2019re often brand-specific, unlike more commonplace chains, cassettes and chainrings.<\/p>\n

More noise, drag and weight<\/h4>\n

The drivetrain is typically noisier than a conventional drivetrain system because of the idler wheel, and it can sometimes create further friction, given the greater complexity of more moving parts.<\/p>\n

However, it\u2019s important to note that this isn\u2019t always the case. It\u2019s dependent on how well the brand has utilised the design and how well maintained it is.<\/p>\n

Finally, you\u2019re likely to pay a slight penalty in weight with a high-pivot system, due to the longer chain, idler pulley and any additional bearings or guides. That said, given the types of mountain bike this system is generally found on, weight isn\u2019t the target focus.<\/p>\n

Should you buy a high-pivot mountain bike?<\/h2>\n

As ever, it depends.<\/p>\n

When you\u2019re deciding on the best mountain bike<\/a> to buy, you ultimately need to weigh up whether a high-pivot design is best suited to your preferred riding style and what you\u2019re looking to achieve from the bike in terms of its ride characteristics.<\/p>\n

As with any prospective bike purchase, it\u2019s well worth test riding your shortlisted bike to see if it works for you.<\/p>\n

If you want a smooth-riding bike that can plough through technical trails with greater poise, a high-pivot design could be an enticing proposition.<\/p>\n

Conversely, for riders who like to pick their way down a trail, and who are after a more uncensored and visceral experience, the nature of a high-pivot suspension layout dumbs this down somewhat.<\/p>\n

Arguably, a high-pivot system is best-suited to enduro and downhill bikes, where the more rearward axle path translates into a perceivably faster, aggressive and assured feel on the descents.<\/p>\n

For cross-country bikes<\/a> and trail bikes<\/a>, where there are lower weights and a greater focus on climbing and pedalling efficiency, low pivot continues to reign supreme.<\/p>\n

High pivot has made a comeback for a reason, though, and we expect brands to continue to adopt the design.<\/p>\n

Indeed, while high-pivot mountain bikes didn\u2019t quite catch on first time around, advances in drivetrain, suspension and frame technology mean mitigating the design\u2019s drawbacks is easier than ever.<\/p>\n
