There are four bikes in Marin’s Rift Zone range. They span a wide price range – from a relatively wallet-friendly £1,700/US$1,999.99 to a don’t-tell-the-other-half £3,500/US$5,099.99 – but share a few ...
There are four bikes in Marin’s Rift Zone range. They span a wide price range – from a relatively wallet-friendly £1,700/US$1,999.99 to a don’t-tell-the-other-half £3,500/US$5,099.99 – but share a few things in common: 29er wheels and 100mm (3.9in) of travel at each end are the obvious links, but they also boast exactly the same 6061 aluminium chassis. The XC8 occupies the rung just below the top. With its blend of XT transmission and Fox shocks, is it the right blend of performance and value?Ride & handling: Puts the fun back into big wheel territoryDespite the fact that it’s all but impossible to walk into a bike shop now without being greeted by rows of big-wheeled bikes, there’s still a fair bit of resistance to the idea from many riders. The good news is that bikes like the Rift Zone prove there’s no need to worry. Once you’re on board and riding you’ll forget the wheels are around 3in bigger in diameter than ‘normal’ ones.Actually, scratch that. You won’t worry about it, but you’ll certainly notice it. In a good way. Because the Marin takes all the good bits of 29er wheels – smooth rolling, mostly – and leaves the bad bits – sluggardly handling, principally – behind.Partly this is down to a wheelset that minimises the inherent rotating mass disadvantage that all big wheels have over the 26in alternative. The Rift Zone accelerates and climbs better than its near-13kg (29lb) weight might suggest, though it’s not in the same league as a race bike. But that’s okay, because it’s not trying to be a race bike. It’s also absolutely sorted in terms of geometry, with a willingly plantable front end that’s as much fun to chuck around as most of the smaller wheeled, longer travel alternatives. It’s hard to overstate just how important an agile front end is to the overall feel of a big-wheeler. By getting this bit right, Marin have given the Rift Zone a big ol’ dose of fun.The final link in the ‘big wheels good’ chain is Marin’s tweaked Quad Link system, which seems better suited to the 100mm of the Rift Zone than longer travelled bikes elsewhere in the Marin range.Fox’s CTD does a good job of controlling the setup’s inherent small-bump plush, while the steep rising rate at the upper end of the travel is delivered so progressively it never feels like an issue.Perhaps the biggest compliment we can give is that it helped us clear a rock-filled gulley that’s defeated us for years. Racers might want something lighter, but for us it’s a reminder that big wheels can do trail fun too.Frame & equipment: On the heavy side but solid specAlthough Marin’s long-running, compact Quad Link suspension design has its fans, it took up an awful lot of space inside the bike’s main triangle – leaving nowhere to put a water bottle. More seriously for Marin’s designers, it didn’t work too well with bigger wheels. So the new, reworked Quad Link puts everything in a, well, more ‘normal’ position. It all works in pretty much the same way as before, with a rear axle path that maximises small bump responsiveness, and a rising rate that ramps up sharply near the limit of the shock’s travel (although a bit less sharply than before). It just doesn’t look different from all the other full sussers out there any more. Depending on your perspective, that might be a good thing… Or not.New for 2013, Marin’s adoption of a 142x12mm rear end adds a claimed 15 percent stiffness to the swingarm and, in the process, cures one of our niggles with the new design (that it was a tad flexy in the rough). Tucking the rear brake calliper away inside the stays is a neat touch, there’s space to run the cable for a remote dropper post under the top tube and Marin’s lifetime bearing warranty still holds.

Stated tire sizes can be notoriously random, with one company's "2.3-inch" or "23mm" sometimes differing significantly from identically badged tires from another brand – and possibly neither measuring true to size. Occasionally, there are even inconsistencies within a brand. I can't magically make every hot stamp adhere to reality but I do have a solution – state the rim width at which they measure the labeled size.Predicting the width of tubulars is relatively simple. After all, they have almost perfectly circular cross-sections so if you know the circumference of the casing (in this case, its width before stitching), you can calculate the diameter – easy as π.Clinchers are trickier. While the cross-section is still nominally circular when inflated, the tire itself only comprises part of the circumference. Plus, the internal bead-to-bead width can vary wildly from rim to rim with drastic effects. For example, a "700x23mm" road tire could measure 21mm on one rim but 25mm on another.Hutchinson's old Intensive Road Tubeless tire was marked 28mm, but was actually much narrowerUnfortunately, rim widths are becoming more divergent, not less – and it's critical to note that we're talking internal width here, not external. For example, Mavic's latest Cosmic Carbone 40 C clinchers have an internal width of just 15mm while HED's new Ardennes Plus extrusion is nearly 20mm across – a full 33 percent wider. Likewise, Easton's supposed "all-mountain" Haven Carbon rims are 21mm wide while Syntace now has its 'MX' series of wheels with widths up to 33.5mm – nearly twice that of Mavic's current Crossmax SLR.Tire makers therefore base stated measurements on the rim dimension they think a rider will use. It seems they have a 50/50 chance of getting it right — and a 50/50 chance of having a satisfied customer.The fix is conceptually easy: just add another number to the label.Adding a little more information wouldn't cost much, but it would add a lotBontrager and WTB once attempted to institute a more informative label ("XX/YY") several years with the "XX" designating the maximum tread width and the "YY" denoting the maximum casing width. In this way, buyers could theoretically get a better idea of how a tire might behave on the trail. It was a good effort but one that ultimately didn't catch on.Instead, I propose that the additional number should be the internal rim width on which the printed tire size is based, such as "700x23(19)" or "27.5x2.25(22)" and so on. This shouldn't be terribly onerous to do. After all, manufacturers should already be basing claimed tire widths on a certain rim width. And they are certainly already printing information on the side of the tires.Riders would still have to incorporate a slight correction factor depending on their own rim width, which means they'd have to know what it is in the first place. But this would provide a more realistic guideline for how a tire will end up in the real world. In other words, win-win.I spoke with Keith Bontrager about the tire labeling issue and he suggested that tire companies would also possibly have to readjust their sizing protocols to better reflect modern usage."The older version of the tire size protocol was IRC's thing," he said, referring to IRC Tire. "The tires were installed on very wide rims, inflated to 60psi, left that way for 24 hours, topped back up to 60psi and then the casing was measured. If it was a 2.1", it would be within a millimeter of that in that state. Casings stretch when they are new so the high initial pressure and time were useful. The tire was much closer to its final dimensional state afterwards. Recall that 10 years ago there were no high-end rims at that width, and no one rode with 60psi off-road. Tires that were 'on size' when measured were too small on a 17mm rim at 30psi."Bontrager said printing the internal-rim width would be good, "if everyone wants to do it right. You'll need a pressure spec (one

While much of the cycling world’s attention has been focused on the Giro d’Italia in recent weeks, last week’s Amgen Tour of California also demanded attention. This year’s eighth edition of the race was held over eight hot stages and finished on Sunday with Tejay van Garderen (BMC) taking out the general classification. Van Garderen took the overall lead after stage 5; a stage that was won by Jens Voigt (Radioshack-Leopard) who put in a late attack from the breakaway he helped create. The 24-year-old van Garderen went on to win the stage 6 ITT and held on to his overall lead on the final two stages to win his first ever stage race. The win bodes well for BMC’s fortunes at the upcoming Tour de France with Cadel Evans also proving he’s in good form. But will BMC ride for Evans or for van Garderen? And is van Garderen good enough to win the Tour de France? He was fifth overall last year (and 1st in the best young rider classification) and he seems to have improved since then (he was 5th in the Tour of California last year). Van Garderen himself told reporters after the final stage: “There’s a big difference between being up there and winning,” he said. “I think I’ve finally showed I have the full package, having the patience and maturity.” So what do you think? Could van Garderen win the Tour de France if BMC were to ride for him? While you’re pondering that, check out this gallery of terrific shots from photographer Wil Matthews from the Tour of California. p.wp-caption-text, dd.wp-caption-text { width: 1150px; }

After a rest day today the Giro d'Italia resumes tomorrow with a 238 km stage from Valloire, France to Ivrea in Italy.Riders will first tackle Mont Cenis from the opposite direction of Stage 15; in this direction 9.8 km at 7%, 10% max. Nearing the finish, with 18 km remaining, riders will be challenged on the Andrate, 6.3 km at 8,1%, 13% max. The last 18 km are 10 km of descent and a flat 8km to the finish.Will the sprinters stay in enough contact on Andrate for a sprint finish?Weather: showers are predicted, freezing temperatures on Mont Cenis.Vincenzo Nibali, Maglia Rosa, today: "The Giro d'Italia is not finished, we still have to deal with at least three very difficult stages; it is early to be getting carried away. We have to pay close attention to an opponent like Cadel Evans, but there's not only him in the fight for the lead in the overall standings."Follow on Twitter: ITALIANCYCJOURN or receive an email when new content is added using the "Follow by Email" button on the right side column.
