Gravel bikes have been experiencing a renaissance over the previous a number of years.
It wasn’t that way back that the majority severe riders would scoff at throwing chunky tires on a gravel body to get extra versatility, as an excellent hardtail mountain bike might possible do the identical factor, solely higher.
Naturally, a full-suspension gravel bike could look like a stretch for some. However as gravel driving matures, so too have the rigs accessible for the bizarre in-between areas.
Cannondale’s newest full-suspension Topstone Carbon Lefty gravel line marks a major step into that kind of specialization, concurrently striving to be a motorbike that’s as environment friendly on the street as it’s compliant within the tough.
The Cannondale Topstone has been the model’s key gravel rig for years. However the newest model encompasses a sharp carbon body and trail-smoothing entrance and rear suspension, making the Topstone among the many most comfy gravel bikes.
After spending 2 days on the Topstone Carbon 2 Lefty within the Colorado mountains, I really feel like Cannondale has give you one thing that isn’t exaggerating when it says “nothing is impassable.”
Topstone Carbon 2 Lefty
Cannondale’s Topstone Carbon 2 Lefty isn’t the most costly possibility within the Topstone lineup, however it’s concerning the closest factor to a mountain bike as you’ll discover in a drop-bar gravel bike. Nonetheless, that is decidedly not a mountain bike or a street bike for that matter.
It’s a particular form of platform that felt prefer it reached as much as fill gaps between street and filth, reasonably than making compromises. It by no means actually strayed too far towards the texture of a street or mountain bike to make it something aside from a devoted gravel rig.
I spent 2 days placing greater than 70 miles on the Carbon 2 Lefty on a mixture of street, gravel, and singletrack in Aspen, Colorado. I made positive to punish my physique to one of the best of my means to see how the bike held up.
These 70 miles got here with practically 3,000 ft of elevation every day on assorted terrain. I acquired an excellent really feel for the way the bike features in all kinds of situations. For a rider based mostly in Austin, Texas, that form of elevation is one thing I all the time must journey for, and it’s all the time punishing on my physique.
The Topstone proved to be the companion I wanted to scale back a few of the fatigue that might normally reduce my time within the saddle quick at increased elevations.
Descending, the bike was quick, enjoyable, and snappy. Cannondale’s Kingpin rear suspension helped the bike hook as much as filth and rocks to stop sliding out. Likewise, the Lefty Oliver Fork made large impacts really feel much less extreme.
The suspension setup created extra dealing with compliance whereas decreasing the fatigue many gravel riders really feel constructing of their arms, fingers, and backs throughout large rides.
I continuously discovered myself searching for out kickers to spring myself off of. I felt comfy within the information that my wrists wouldn’t buckle from a front-heavy touchdown due to the Lefty. The rear wheel felt glued to the bottom, so coming into corners sizzling wasn’t as problematic as on inflexible bikes.
The rear suspension supplies 30 mm of journey on the saddle. You get a further 10 mm or so of rear axle journey as a result of rear triangle body flex.
The Lefty fork delivers 30 mm of journey. It isn’t a lot, however it created simply sufficient flex to really feel responsive and playful whereas retaining effectivity on climbs and sprints when situations referred to as for it.
The Carbon 2 Lefty additionally encompasses a dropper publish, which is a type of options that appears to scream “off-road” on the prime of its lungs. It gave the bike a good better feeling of functionality, particularly whereas pointed downhill.
The bike nonetheless felt like a snug climber. It didn’t bob underneath drive, and the identical flex that helped it monitor nicely in livid descents saved me from getting bumped out of the saddle whereas creeping over roots and rocks on steep-graded singletrack.
Taken alone, the Kingpin, dropper, or Lefty Oliver fork would all be welcome additions to my inflexible gravel bike. Taken collectively, they’re extra of a revelation. Regardless of my lungs and legs burning, I used to be remarkably comfy over each sort of terrain.
The Topstone Carbon line is obtainable in inflexible and suspension fork choices, however all characteristic Cannondale’s Kingpin suspension system.
With the Kingpin setup, the again of the Topstone body flexes round a through-axle pivot positioned on the seat tube to create an built-in rear suspension that doesn’t require a shock. As a result of it features by means of flexing, it doesn’t have a real bottom-out mark and doesn’t require servicing like different suspension methods.
It’s a bit counterintuitive. Carbon normally is lauded for its stiffness, which provides riders extra effectivity by means of the switch of energy by means of the body. Cannondale has as an alternative used carbon as a pliable materials to extend consolation and compliance, not rigidity.
Whereas driving behind a Topstone Carbon, I noticed the flex of the bike, however it’s not one thing I felt whereas driving in the identical approach as a conventional air or coil shock. The flex was adequately subtle that I forgot about it till I noticed that the terrain ought to have felt more durable, or I took a large enough hit to acknowledge it.
Kingpin made a very spectacular distinction when descending in broadly various situations or whereas peddling over chunky gravel or single monitor. The motion of the body’s rear helped the bike’s tires monitor the bottom persistently. That feeling contributed to much less time spent chattering into corners or drifting.
The Carbon 2 Lefty’s dropper publish made the bike really feel like an ultra-stable platform whereas descending, even at speeds of 40 mph or extra. The low heart of gravity the bike afforded me was confidence-inspiring irrespective of the terrain.
Utilizing the dropper publish barely inhibited the bike’s quantity of journey, because the Kingpin is supposed to flex all the way in which as much as the rider by means of the seat publish. However the movement makes a giant distinction with both setup.
The bike has sufficient house for 700c x 45mm tires or 650b tires as much as 2.1 inches. However the additional assist from the entrance and rear suspension offers related ranges of compliance with smaller, sooner, and lighter tires. Most inflexible bikes might solely discover that with greater choices.
The Lefty Oliver gravel fork introduced 30 mm of journey to the entrance of the bike, turning mild gravel into butter. And it considerably smoothed out extra technical terrain, together with tough gravel roads and singletrack trails peppered with rocks and roots.
Even massive potholes on the street that might ship riders over the bars in a heartbeat felt like small bumps. The Lefty Oliver’s progressive tuning solely kicked in when the bike took a large enough hit to generate a response. Typically, particularly whereas climbing, I wasn’t conscious that the shock was doing something in any respect.
I didn’t really feel massive, springy actions or dramatic flexes that appeared like energy dumps except I put my physique’s full weight into the bars. For these instances once I absolutely loaded the entrance, the fork encompasses a full lockout possibility that stiffened issues up.
Whereas driving the Topstone Carbon 2 Lefty, I used to be surrounded by others driving the rigid-fork sibling, the Topstone Carbon 1 RLE. The numerous variations between these two bikes are the Carbon 1 RLE’s inflexible fork and its included SmartSense system.
Cannondale says it doesn’t embody SmartSense within the Topstone Carbon Lefty fashions to maintain the worth down, which is comprehensible. It’s already giving riders a full-suspension, carbon gravel bike with a fork that prices greater than an MSRP of $1,500. Throwing SmartSense on might value out a big contingent of consumers.
Nonetheless, the Carbon 2 Lefty is constructed to simply accept the system, ought to riders choose to spring for the extra money, as are all Topstone Carbon fashions.
SmartSense is a completely built-in radar and lightweight system that features the Garmin Varia Radar, Lezyne entrance and tail lamps, and a Cannondale wheel sensor. A single battery that mounts to the body powers the entire system. It begins robotically when the bike strikes and makes use of mild and sound alerts to make sure that riders are conscious of approaching site visitors and vice versa.
Riders can customise and management the system by means of Cannondale’s app. Solely the higher-end fashions of the rigid-fork Topstone Carbon come geared up with SmartSense. With out the system put in, the battery mount within the body features as a spare tube or instrument storage space.
