New carbon fiber speed machine from Santa Cruz
By James Huang
Santa Cruz has taken its popular Blur XC in a new direction for 2009 with the introduction of an all-new carbon fiber frame. According to Santa Cruz PR man Mike Ferrentino, the new frame is substantially lighter, dramatically stiffer and yet even more durable than the outgoing aluminum version.
Claimed weight for a medium frame is now an impressive 1948g (4.3lb) including a RockShox Monarch 3.3 shock, down from 2359g (5.2lb) for last year's model, and a complete bike with a not-too-exotic Shimano XTR build is supposedly just 10.15kg (22.38lb). In addition to the carbon fiber main frame and rear triangle, Santa Cruz also uses the material for the upper link, both rear dropouts and even the rear disc brake tabs.
Even so, Santa Cruz claims the new Blur XC rivals some of its big-travel bikes for strength – there is no rider weight limit – while the purported increases in rigidity (the company doesn't say exactly how much but says it "blows away" the old one) should yield improvements in pedaling response and handling precision as well. All heady claims for sure considering this is Santa Cruz's first-ever carbon bike and we'll do our best to secure a test sample as soon as possible.
The decreased weight suggests a more race-oriented bike than before but the geometry numbers reinforce this notion even further. For comparable large-sized frames, the carbon model drops to 105mm of rear wheel travel (down 10mm), the shock stroke shortens to 165mm (down from 200mm), and the chain stays shrink a considerable 7mm to just 422mm (16.6"). In keeping with industry trends, head tube angles slacken a bit to 69.5° across the board for marginally more stable handling though and the head tube lengths have also grown a few millimeters. Geometry is optimized around 100mm-travel forks but 120mm ones will also work well.
Santa Cruz will offer the new Blur XC in four sizes – small, medium, large and extra-large – and in either black or silver. Not surprisingly, the new performance capabilities will also come with a substantial increase in price: the new Blur XC will fetch US$2299 (anodized aluminum Blur XC frames were US$1999) when it becomes available in the US around mid-March. As always, Santa Cruz will also offer complete bikes ranging from US$4669 to US$6281.
Santa Cruz在09年推出的一个新的全碳车架，新的车架实际更轻，更硬。耐久度上比即将离任的铝版本更高。
非常令人惊奇，声称中号车架的重量只有1948G(4.3lb)包括咯RockShox Monarch 3.3 的后避震。比老版本铝车架的2359G轻.其整车使用SHINAMO xtr也才10.15kg (22.38lb)，此外车架使用了碳纤维的框架和后三角。在连接材料上也使用了碳纤维，甚至在碟刹座上也是碳纤维。
即使如此，Santa Cruz 声称新款的 Blur XC没有限制骑手的重量，（个人意见：中国好像没有体重超标的人，至少在湖南是这样的）刚性个硬度有所增加（但是官方没有给出增加数值与老版本进行比较），提高的踩踏的效率和操控性。以上所以的消息都很令人振奋，这是Santa Cruz 的第一辆碳纤维自行车，我们会尽最大努力，在第一时间拿到试验样品进行测试。
Santa Cruz 新款的Blur XC拥有4个型号S M L XL,普通版本有黑色和银色，不足为奇的是，车架在性能有大幅度提高的时候，价格却只有2199美元（老款阳极电镀也需要1999美元）。新款的Blur XC将在09年3月中旬面世，同样Santa Cruz也推出了整车系列，可以供大家选择。
