Anyone who follows the motorsports scene knows how special the name Ohlins Racing is. They also know that those signature bands of yellow and blue on the machines of top moto enduro racers are there not because of sponsorship, but because the athlete sought them out. With the 29in RXF 34 140 Fork, that same sweet, sponsor be damned quality is available for the first time in a mountain bike fork. Ohlins being Ohlins, we're not surprised that it came up with a design that's truly unique in the mountain bike field. In fact, we'd be disappointed if it hadn't. The RXF 34 is the only fork on the market to feature a twin tube damper, which separates the rebound and compression oil flow. Since the twin tube design lets the oil flow parallel and independently, the fork maintains optimal pressure at all times, riding higher with a smoother initial stroke. It maintains consistent, predictable small bump compliance across successive hits to leave you more in control of your lines and with more responsive traction. The fork's spring also incorporates a unique addition. It's got an additional positive chamber, adding a third member to the typical air spring loadout of one negative and one positive. The presence of two positive chambers means that the resistance can be dialed externally to alter the compression curve, so the fork can be set to maintain that initial suppleness but ramp up harder to avoid bottoming out on big hits all without the need for internal spacers. Given the host of absurdly versatile all mountain 29ers we've been seeing unveiled over the past year, this added versatility in fork suspension is not only a plus, we suspect it'll become a necessary feature by the next product cycle. The fork climbs with confident traction but won't sell you out by diving on rowdy descents. And now we get to the elephant in the room: those 34mm stanchions. When we first saw a spec sheet for the RXF, we scrolled through looking for a 35 or a 36mm model and were surprised...
