The Tracer LegacyThis test explores the attributes of the 27.5-inch-wheel version of the Intense Tracer - the latest chapter in the development of the Southern California bike maker's most popular aluminum-framed trail bike. Intense launched the Tracer in the year 2000 with Horst-link suspension, slacker frame geometry, and a more downhill-friendly cockpit than the typical XC bikes of the time. It could be argued that the birth of the Tracer marked the rebirth of the trail bike. Today's Tracer has VPP suspension, almost double the wheel travel of that first model, and its steering geometry is slacker than the downhillers of that era, but its purpose remains steadfast - to blend the traits of a good climber and descender into one bike that shreds all. With the adoption of 650B wheels, the Tracer 275 has the potential to take the classic trail bike to the next level, but before diving into a wheel debate, we investigate the back-story of Intense's latest shredder.
Intense now offers the Tracer in all three wheel diameters, so the 275 benefits from an evolutionary design process. Intense founder Jeff Steber was an enthusiastic early adopter of the 29er. After Steber had successfully honed the 29er version into the Tracer of his dreams, he was armed with the real-world information necessary to blend the velvety roll-over and in-the-bike feel of the 29er with the precise steering and snappy pedal feel which are attributes of a 26er. The seemingly rapid development of the Tracer 275 was made possible by the fact that Intense makes, welds, heat treats and finishes nearly every part of its aluminum frames in their Temecula, California, factory - so Steber, who still designs and constructs prototypes there, can make changes as necessary, regardless of how large or minute they may be. With trails ranging from pro DH to flowy XC within minutes of the building, Steber and his trusted hard men can immediately evaluate modifications in geometry or suspension and be back making new parts the same day. While the handling and performance qualities of 26 compared to 29-inch-wheel bikes are an obvious contrast, assessing the more subtle differences between those and the mid-size, 27.5-inch wheel would be difficult at best without the rapid prototyping and evaluation capabilities that Intense enjoys.

Tracer 275 ConstructionThe 275 frame is assembled on different tooling than 26 and 29-inch Tracer frames because its geometry is unique in order to maximize the attributes of its chosen wheel diameter. Tracers are primarily constructed from Easton 6000-series alloy taper-butted and manipulated aluminum tubes, although the top tube/seat tube strut is hydroformed from flat aluminum and then welded into an efficient, one-piece structure. Intense makes the frame's suspension rockers, dropouts, bottom bracket shell and shock mounts on its network of CNC machining centers. Even threaded bits like the adjustable suspension pivot hardware are made in-house. Tracer frames feature two travel options: 5.5 or 6 inches (140mm, 150mm) and are recommended for forks in the 150 to 160-millimeter travel range. The 275 is described by Intense as suitable for trail, all-mountain and Enduro, so the chassis is built tough enough to compete at the highest level of Enduro, as well as to handle the wide range of riding styles that all-mountain encompasses. Big-hit toughness, however, comes with a weight penalty. A medium Tracer frame with its Fox Float CTD shock weighs 7.8 pounds, which is competitive within the realm of AM and Enduro, but a pound off the mark for carbon-friendly XC/trail riders. Our medium-size Shimano XT equipped test bike weighed 30.7 pounds without pedals.
Tracers have ISCG-05 chainguide mounts at the bottom bracket and internal and external routing for a dropper seatpost. Out back, heavy duty G1 replaceable dropouts house a 142/12mm through-axle. As is the practice now, the G1's massively rigid hanger ensures that impacts to your rear derailleur will not bend the hanger and shove the mech into the spinning spokes. In most cases, it will be shifting properly when you return, or be dangling by its cable. The front changer has a direct-mount boss to place it correctly in space, as the seat tube is bent forward for tire clearance. On the subject of tire clearance, there is room for rubber up to 2.5 inches wide, although real estate is cramped near the top of the tread at both the seat stay and chain stay bridges of the swingarm. There are no bottle mounts to be found anywhere, as proper stand-over clearance and shock placement trumps most of the available space in the Tracer's frame. Serviceability is ensured by full-length housing and hose runs, a threaded bottom bracket shell and press-in headset cups, as well as adjustable angular-contact bearings in the suspension pivot locations. Grease fittings are installed on the vulnerable lower rocker link so the bearings there can be routinely purged of grit or moisture.
Tracer 275 Suspension Santa Cruz shares its patented VPP dual-link suspension with Intense, so the Tracer 275's shock tuning and suspension rate curves reap benefits from two design teams. What that means is efficient, firm pedaling at the sag position, with smooth, linear-feeling suspension through the mid-stroke and just enough of a rising rate towards the end-stroke to mute maximum events. Rocker links pivot on stiff, 15-millimeter shafts and angular-contact-type ball bearings. If any free-play develops in the pivots, it can be easily tuned out using collet-style adjusters at each location. Two mounting positions for the custom-tuned Fox Float CTD shock on the upper rocker link provide either 5.5 or 6 inches of rear-wheel travel. Switching to the shorter option firms up the feel of the suspension slightly, but does not affect the bike's bottom bracket height or its frame numbers. We rode most of the test intervals with the shock in the six-inch position.

Tracer 275s have about 1/4 inch (6mm) less suspension travel than their 26-inch-wheel siblings - presumably to circumvent potential tire-clearance issues. (Clockwise) Widely spaced bearings on the lower VPP link boosts the Tracer's lateral stiffness. The one-piece swingarm employs oversize tubes to further maximize the frame's rigidity. Two positions on the Tracer 275's lower shock mount determine rear-travel options. |
Intense paired the Tracer 275's 160-millimeter rear end with a 150-millimeter-stroke Fox 34 Float Kashima CTD fork. Armed with 'Climb - Trail - Descend' options on both ends, Tracer 275 riders have the ability to maintain the bike's ride height with three tuning combinations by matching the CTD selections on the fork and shock. The magic of the VPP suspension design, with its good balance of pedaling firmness and smooth suspension action was such that we rarely twisted either CTD dial. The notable exception was our preference for the nearly locked out 'Climb' option for long highway stints. Before you infer that the Tracer 275's suspension is bob-free under power, it is not. The Tracer's rear suspension is configured to remain effective both under power and while braking, so the shock will cycle slightly most of the time when pedaling.
Tracer 275 Standout ComponentsOnce exclusively a frame builder, Intense now regularly ships complete bikes, furnished with a number of standard build kits. Our test bike is based upon the Shimano XT 'Expert' kit, which would normally result in a MSRP of $4800 USD, but our Tracer was upgraded with a RockShox Reverb dropper post and Sun Ringlé Charger Expert tubeless-ready wheels, so its sticker price would be significantly higher. Rolling out with a best-of class dropper is always a good thing - and Charger rims are licensed by Stan's, so you know that they will be excellent tubeless performers. Shimano XT Trail brakes with ICE rotors join the Tracer's best-of list, which is topped off by Kashima-coat Fox suspension and a sweet Cane Creek headset. The only questionable choice in the Tracer 275's near perfect all-mountain/trail component selection was its Shimano XT triple crankset. The only visible wear the teeth received on the 42-tooth chainring was inflicted by the rocks and logs we bashed on the trail. A two-by-ten drivetrain would have been perfection.

TRAIL REPORT:
Riding the Tracer 275

The most noticeable improvement that the larger wheels bring to the ride is a precise feel over the faster sections of the trail.
 | Regardless of intent, our first rides aboard the Tracer 275 were going to be heavily colored by preconceptions based upon the bike's 650B wheels. Were we weighing the performance of a familiar bike, adapted to a new wheel size, or were we riding a completely new design to be judged upon its own merits? Much of that mystery was put to rest during the roll-around check rides required to get the suspension and cockpit dialed in. Turns out, the Tracer 275 feels a lot like a contemporary trail bike. |
Suspension Setup: The suspension rate-curve that Intense chose for the 275 requires a good deal of pressure in the shock-spring. Use the push-on-the-saddle method to assess its spring pressure and you would swear that it is way too stiff, but under saddle, the suspension settles into its ride height and the shock then feels quite plush. Set the shock at 30-percent sag and the Tracer will deliver the smoothest ride over the chatter without bottoming on larger impacts. That worked out to 200psi for a combined rider and gear weight of 175/180 pounds. We pressurized the Fox 34 fork to about 75 psi. The result was a good fore-aft balance with a little extra stiffness in the fork to keep the Tracer riding level on the downhills.
Pedaling/acceleration: Weighing in at a touch over 30 pounds and with slightly heavier rolling stock than a 26-inch trail bike, the Tracer 275's rate of acceleration falls between that of a snappy feeling all-mountain and an overweight XC bike. That said, the 275 feels quick enough at the cranks to pepper a long-day's ride with maximum efforts, and its weight is seldom noticed, as the Tracer's balanced cockpit and easy handling allow its rider to quickly forget about the bike and get to the business of shredding. We tried various combinations of 'Climb-Trail-Descend' on the fork and shock during early testing and decided that, unless we were rolling on pavement, the 275 pedaled well enough to leave it wide open on 'Descend' the whole day. For the rare, smooth, flowing XC/trail ride, choosing 'Trail' mode with the pedaling platform set somewhere in the middle of the range made for a brighter, slightly firmer feel under power. Running both ends on 'Climb' raised the bike's ride height on trail, which eroded its feel to some degree.
Climbing:. The first clear indicator of the 275's handling with regard to its wheel diameter was that the bike's front end stayed put and steered well while grinding up steep, technical trails. Unlike 29ers, which due to their long chainstays are comparatively heavy up front, the Tracer maintains a better balance. Little or no attention is required to keep its rear tire biting, and its front tire can be easily lightened to clear steps or roots without an exaggerated weight shift. In similar situations, a typical 26-inch-wheel trail bike's front wheel would be skipping all over the place unless its pilot took corrective action. As a result, the Tracer 275 redirects energy and concentration that would normally be wasted maneuvering the bike, towards the more important task of pedaling to the top of the hill. Like most bikes that fall near the all-mountain category, the six-inch-travel 275 climbs most efficiently while its rider is seated. We learned to maximize the effects of our out-of-the-saddle efforts by choosing the most opportune moment to throw-down on a climb.
Descending/technical performance: When pressed hard, there are many moments when the Tracer acts much like a regular mid-travel 26-inch AM/trail bike. There is no sense when jumping that the 275 is unusual, and if you make a mistake, it can land controllably from odd angles. The Tracer's steering is accurate, it is easy to manage under maximum braking, and both its feel and lean angle in the corners are equivalent to what one would expect from a good 26er trail bike with modern, slacked-out geometry. Descend a fast, nasty section of singletrack at full tilt, however, and the Tracer 275 shows a clear advantage over all comers. It can get from hard right to hard left and back again with a quickness that a 29er does not match - and it can easily hold a line where an equivalent 26er would be starting to struggle. The 275 also feels confident when handling parallel ruts and off-camber situations. To what degree those traits belong exclusively to the Tracers's wheel selection or to its frame metrics is speculation. There is no doubt, though, that the 275 likes to go fast.
 |
The Tracer 275 can hold a tight line in the rough and it is a smooth jumper - both are attributes that play well for hard-charging trail riders. |
Component Report:• The Fox Float 34 fork was initially too stiff in compression in the mid-stroke (
typically, our complaint is that the Float 34 fork blows through the mid-stroke), which was a concern until the bushings eventually broke in and the sliders smoothed out. With added control in the mid-stroke, precise feeling at the handlebar and lighter weight, the 34-platform is emerging as the go-to for the AM/trail category.
• The Sun Ringlé Charger Expert wheels went the distance and were easy to convert to tubeless, thanks to their Stan's NoTubes influence. We burped the rear tire once at low pressure on a rocky off-camber descent, but otherwise it was green and go for two months in the boulders. We never touched them with a spoke wrench.
• It is great to see Kenda back 650B with a classic tire like the Nevegal, but it is a bit dated. We'd love to try a similarly aggressive tread pattern on a more supple, high-volume casing. Presently, there are a lot of tire options for 650B with more just around the corner.
• Shimano's triple-ring XT crankset performed beautifully, but the two chainrings we used most - the 24-tooth granny and 32-tooth middle ring - are redundantly close. A wider-spaced two-by crankset, like a 24 x 36 or 38 would be better suited to the Tracer's appetite for quickly changing technical terrain. We bashed the XT's 42-tooth big ring more times than we shifted onto it.
• Funky external hoses and housings - no. RockShox Reverb Stealth - Yes.
• Fox CTD: Granted that there are many riders who need three pedal settings for their rear suspension, but the fact that the 'Trail' option has a widely adjustable pedal platform begs for the elimination of the 'Climb' setting - at least for longer-travel designs. Two options would make it quick and sure to switch from 'open' to 'platform' on-the-fly - and would be more useful for fast-paced, technical riding styles.

Making a Case for 650B
No review of a mid-sized wheel bike can go forth (at least for the time being) without some discussion of the merits of 650B and its place in the scheme of 26 and 29-inch standards. The either/or choice between a 26-inch or a 29-inch wheel bike is clarified because, beyond their unique handling and feel, the two designs also look dramatically different. Show up on a 29er and everybody knows what it is. Ride all day with a group on a 650B bike and, unless somebody reads the hot-patch on the tires, chances are you will never be singled out. It's not an easy sell.
If you are big-wheel curious, the 29er is the logical choice because it offers the extreme experience - all the good and all of the bad aspects of larger wheels in one easy-to-understand package. If you want to fast-track your mountain bike skillset, then 26 is the choice, because for over 35 years, every trick in the mountain bike book has been written for 26 inch wheels. The mid-size wheel lacks the flash value of either extreme. The evolution of 650B is more of a logical step that unites proven attributes of the two accepted standards, and it makes the most sense in the long-travel trail bike realm, where small-wheel bikes could use a boost in rolling efficiency and attempts to mate long-travel with big wheels results in missing chromosomes.
For all-mountain/trail riders, the promise of 650B is a performance package that sacrifices some of the 29er's roll-over qualities and a little bit of the 26er's nimbleness in order to focus the lion's share of those attributes into a bike that is more versatile than either of its parents - one with just-right cockpit ergonomics, familiar handling characteristics and uncompromised suspension action. The takeaway of a well-designed 650B bike is defined by hundreds of small events over the entire ride that compound the experience, rather than a few shining moments. The wider the variety of terrain, the more one begins to appreciate the concept. An 'ah-ha' 650B moment on the first ride? Probably not, but after few good laps, the advantages start to pop and the 650B begins to feel less like a hybrid and much more like a whole new animal.
Pinkbike's take: | Judged purely upon its performance and ignoring any reference to competing wheel sizes, the Intense Tracer 275 is the real deal for those searching for a hard-charging descender that is bright enough on the climbs to stay in the game all day long. At 30 pounds and some change, the 275's weight is probably not going to capture the imagination of Mister Strava P. Spandex, but Intense has always played to a harder crowd. The 275 is tough, its suspension is deep, and its capable geometry is built around the larger fork platforms that are the staple of both all-mountain and the emerging crop of Enduro riders. And 650B? We would be remiss to say that every PB test rider loved the feel of the mid-sized wheels. Intense dedicated the frame and steering metrics of the Tracer 275 exclusively to 27.5-inch wheels, and riding it to full advantage requires a slightly different sense of timing which takes a while to acquire. Is it the right bike for you? The 275 was brought to life by a group of knowledgeable, experienced bike handlers who wanted to go big and take advantage of larger wheels. If you count yourself among them, the Tracer 275 delivers the goods. - RC |
