Gravel bikes have been experiencing a renaissance over the previous a number of years.
It wasn’t that way back that the majority critical riders would scoff at throwing chunky tires on a gravel body to get extra versatility, as hardtail mountain bike may doubtless do the identical factor, solely higher.
Naturally, a full-suspension gravel bike could seem to be a stretch for some. However as gravel using matures, so too have the rigs out there 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 contains 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 costliest choice 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. Nevertheless, 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 the most effective of my means to see how the bike held up.
These 70 miles got here with almost 3,000 ft of elevation every day on diverse terrain. I obtained really feel for a way the bike capabilities in all kinds of situations. For a rider based mostly in Austin, Texas, that form of elevation is one thing I all the time should journey for, and it’s all the time punishing on my physique.
The Topstone proved to be the companion I wanted to cut back among the fatigue that will normally reduce my time within the saddle brief 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 lowering the fatigue many gravel riders really feel constructing of their arms, fingers, and backs throughout large rides.
I regularly discovered myself in search of out kickers to spring myself off of. I felt comfy within the data 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 scorching wasn’t as problematic as on inflexible bikes.
The rear suspension gives 30 mm of journey on the saddle. You get a further 10 mm or so of rear axle journey on account of rear triangle body flex.
The Lefty fork delivers 30 mm of journey. It isn’t a lot, nevertheless it created simply sufficient flex to really feel responsive and playful whereas retaining effectivity on climbs and sprints when situations known as for it.
The Carbon 2 Lefty additionally contains a dropper submit, which is a type of options that appears to scream “off-road” on the prime of its lungs. It gave the bike a fair better feeling of functionality, particularly whereas pointed downhill.
The bike nonetheless felt like a cushty climber. It didn’t bob underneath pressure, and the identical flex that helped it observe properly 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 kind of terrain.
The Topstone Carbon line is obtainable in inflexible and suspension fork choices, however all function 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 capabilities by means of flexing, it doesn’t have a real bottom-out mark and doesn’t require servicing like different suspension techniques.
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 a substitute used carbon as a pliable materials to extend consolation and compliance, not rigidity.
Whereas using behind a Topstone Carbon, I noticed the flex of the bike, nevertheless it’s not one thing I felt whereas using in the identical method as a standard air or coil shock. The flex was sufficiently subtle that I forgot about it till I noticed that the terrain ought to have felt harder, or I took a large enough hit to acknowledge it.
Kingpin made a very spectacular distinction when descending in extensively various situations or whereas peddling over chunky gravel or single observe. The motion of the body’s rear helped the bike’s tires observe the bottom persistently. That feeling contributed to much less time spent chattering into corners or drifting.
The Carbon 2 Lefty’s dropper submit made the bike really feel like an ultra-stable platform whereas descending, even at speeds of 40 mph or extra. The low middle of gravity the bike afforded me was confidence-inspiring irrespective of the terrain.
Utilizing the dropper submit barely inhibited the bike’s quantity of journey, because the Kingpin is supposed to flex all the best way as much as the rider by means of the seat submit. However the movement makes a giant distinction with both setup.
The bike has sufficient area for 700c x 45mm tires or 650b tires as much as 2.1 inches. However the further assist from the entrance and rear suspension provides comparable ranges of compliance with smaller, quicker, and lighter tires. Most inflexible bikes may solely discover that with larger choices.
The Lefty Oliver gravel fork introduced 30 mm of journey to the entrance of the bike, turning gentle 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 will 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. Usually, 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 until I put my physique’s full weight into the bars. For these occasions once I absolutely loaded the entrance, the fork contains a full lockout choice that stiffened issues up.
Whereas using the Topstone Carbon 2 Lefty, I used to be surrounded by others using 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 may value out a big contingent of patrons.
Nevertheless, the Carbon 2 Lefty is constructed to just accept the system, ought to riders choose to spring for the extra money, as are all Topstone Carbon fashions.
SmartSense is a totally built-in radar and lightweight system that features the Garmin Varia Radar, Lezyne entrance and taillights, 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 gentle and sound alerts to make sure that riders are conscious of approaching 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 outfitted with SmartSense. With out the system put in, the battery mount within the body capabilities as a spare tube or device storage space.
