Schwalbe的新Radial径向(子午线)胎体没人讨论吗 转一篇Pinkbike评测,AI机翻。 先上总结:Radial胎体更容易形变,所以更贴地抓地力更好。 目前Maigc Mary和Albert以及新出的shredda都已经提供Radial胎体,比老款略贵。 评测:Schwalbe 的 Magic Mary 径向轮胎提供一流的抓地力 Most mountain bike tires are constructed with threads that run at a 45-degree angle from bead to bead. For the sticklers out there, Schwalbe’s tires aren’t a ‘true’ radial, where the threads are oriented at a 90-degree angle to the direction of travel, but the change in orientation is enough to have a dramatic influence on how the casing deforms when an obstacle is encountered. 大多数山地车轮胎的帘线从胎圈到胎圈呈 45 度角排列。对于那些较为严谨的人来说,Schwalbe 的轮胎并不是“真正”的径向——真正的径向帘线应与行进方向呈 90 度角——但帘线走向的改变已足以在遇到障碍物时显著影响胎体的变形方式。 On my scale, the 29 x 2.5” Ultra Soft compound tire weighed in at 1406 grams, and the 27.5 x 2.5” Soft compound tire was 1295 grams. The tires are priced at $108 USD. 在我的秤上,29 x 2.5 英寸 Ultra Soft 配方轮胎称重为 1406 克,27.5 x 2.5 英寸 Soft 配方轮胎为 1295 克。轮胎售价为 108 美元。 It’s important to experiment with different air pressures when switching to radial tires - if you run your typical pressures there’s a good chance the tire will feel too soft and vague due to the difference in the way the tire deforms. I went up 2 - 3 psi higher than my usual DH tire pressures, settling on 22 up front and 24 in the back for my 165 pound weight. Those pressures are for trail riding - I typically add another couple pounds of pressure for bike park usage, where the speeds are higher and the trail surface tends to be firmer. With the thinner Trail Pro casing tires I’ve been running 3 - 4 psi more than I normally do on ‘regular’ tires. 在改用子午线(radial)轮胎时尝试不同的胎压很重要——如果你继续使用平常的胎压,很可能会因为轮胎变形方式不同而感觉太软、反应模糊。我比平常的重型下坡(DH)胎压提高了 2–3 psi,最终定在前轮 22 psi、后轮 24 psi,适合我 165 磅的体重。上述胎压是用于越野(trail)骑行的——去越野公园(bike park)时我通常再加一两磅,因为速度更快且路面通常更硬。对于我一直在用的更薄的 Trail Pro 胎体轮胎,我比平常的“常规”轮胎多打了 3–4 psi。 Wet, slimy conditions are where the Marys excel. There’s a vast difference between how these handle wet roots compared to the non-radial version - the extra compliance makes them more predictable, and they’re much, much less likely to suddenly slide sideways. The traction that they deliver is due more to the mechanical properties of the casing rather than an extra-sticky rubber compound; while the Ultra Soft rubber isn’t as tacky as Maxxis’s MaxxGrip rubber, the way the casing molds over obstacles more than helps make up for that. 湿滑、黏糊的路况正是 Marys 的强项。与非径向版本在湿润树根上的表现相比,差别巨大——额外的顺应性让它们更可预测,而且不太可能突然侧滑。它们提供的牵引力更多源于胎体的机械特性,而不是更粘的橡胶配方;尽管 Ultra Soft 橡胶没有 Maxxis 的 MaxxGrip 橡胶那么黏,但胎体覆盖障碍物的方式在很大程度上弥补了这一点。 I do think that there’s still room in Schwalbe’s lineup for an even softer rubber compound for riders who are willing to sacrifice some longevity for maximum grip (Super Duper Soft?), but as it is, the radial casing helps make the slightly firmer rubber a non-issue. 我确实认为 Schwalbe 的产品线中仍有空间推出更软的橡胶配方,供那些愿意以牺牲一定耐用性换取极致抓地力的骑手选择(Super Duper Soft?),但就目前而言,径向胎体使得稍硬一些的橡胶几乎不成问题。 The amount of grip available when conditions are grim is astounding. I’ve even swapped bikes mid-ride with a friend to confirm that I wasn’t imagining things, and I wasn’t - the way that the tire deforms allows it to find grip where other tires slip. 在糟糕路况下可获得的抓地力令人惊讶。我甚至在一次骑行中途与朋友换车以确认自己没有错觉,结果证明我没有错——轮胎的变形方式让它能在其他轮胎打滑的地方找到抓地力。 These tires have a muted feel that’s distinctly different from non-radial tires. The sensation is similar to the difference between a coil shock and an air shock - small bumps are erased, and there’s a glued-to-the-ground feel that’s truly confidence inspiring. To continue the suspension analogy, it’s almost like running a lighter compression tune - the difference is that dramatic. 这些外胎的感觉较为沉稳,明显不同于非径向胎。这种感受类似于螺旋弹簧避震与气压避震之间的差别——小颠簸被抹平,给人一种仿佛粘在地面上的感觉,确实让人更有信心。继续用减震类比的话,这几乎就像把压缩阻尼调得更轻——差别是如此显著。 If your typical trail surface resembles a pumptrack I’d suggest going with something with a less aggressive tread pattern for better rolling speed. That said, even with those taller knobs and malleable casing the tires remained predictable - I took lots of laps on Whistler’s A-Line and Dirt Merchant trails and didn’t find the handling to be overly vague. The casing deforms more in the center of the tread, but the sidewall support remains, which keeps the handling very predictable; it never felt like the sidewall was going to collapse on me. 如果你平时骑行的山径路面更像是泵道,我建议选择花纹不那么凶猛的轮胎以获得更高的滚动速度。话虽如此,即便拥有更高的胎块和更易变形的胎体,这款轮胎的可预测性依然良好——我在惠斯勒的 A-Line 和 Dirt Merchant 小道上跑了很多圈,感觉操控并不过于模糊。胎面中心的胎体确实更容易变形,但侧壁支撑仍然存在,这让操控非常可预测;从来没有感觉侧壁会在我身边塌陷。 Climbing on hardpacked trails or on asphalt does feel extra-draggy, though; that’s when the tire’s deformation is more noticeable. I could literally hear the knobs getting smooshed against the pavement on one particularly steep approach to the trails. The flip side is that climbing traction is excellent - most people aren't buying a DH tire for the uphill performance, but the Mary does a great job of digging in and holding on during steeper, technical climbs. 在硬化的土路或沥青路上爬坡确实感觉阻力更大;那时轮胎变形更明显。我甚至能在一次特别陡的上坡前往小道的过程中听到胎块被路面压扁的声音。另一方面,上坡牵引力表现出色——大多数人买下坡胎并不是为了上坡性能,但 Magic Mary 在较陡、技术性上坡时能很好地咬住并保持抓地。
29*2.1的重口味瓜Revolt X完成 Revolt至少有一点还是可以吹的,那就是53C胎容,实测29*2.1的Thunder Burt无压力,甚至有点想上Racing Ralph…… 但是做工真挺感人,真一分钱一分货,不管是之前的昆山ADV还是现在的PRO级别的X,桶轴杆用手都拧不动阻力很大,因为尾勾不是很正,不影响使用但是有点让人不爽,再就是毫无意义的内置坐管夹会顶裂漆也是服气。 MKS BUBBLY脚踏吹爆,这是车上花的最不后悔的钱,并且永远不会换掉它。踩踏面是个完整的平面,比所有山地车钉子脚踏都要舒服,面积也很大,注意不要买到小号Tiny版的。 人比较废柴,所以当了垫圈哥,5CM垫圈还得抬升把,主要是这个X架子只买到这个M码,要是有得选我得买L的。 前叉Rudy ULT,水货2860真香,这价格相比之下FOX是什么辣鸡? 之前用过XPLR升降,然后发现5CM升降没什么卵用,就先出掉了,在考虑接下来要不要整75或者100的。但是目前整车带脚踏水壶架9.5KG加个升降可就10KG了有点离谱…… 突然喜欢高框粗胎的风格,所以买了43框高的EXS肠粉Granfondo,很润,我以前用过很多轮子,几千块这个档次的我感觉都骑不出有什么区别,但这个轮子我还没出小区就感觉到它溜车很润了,有点夸张。貌似踩着也挺硬,可能是心理作用,毕竟我FTP50 瓦应该踩不出区别的。 Thunder Burt其实滚阻很低,比很多瓜车胎都低,但是骑太快毕竟侧齿高估计空气阻力就比较大了,适合我这种均速18的选手。 魔改GRX手变,很棒很舒适但也有点贵……肉疼。幸亏最近咸鱼有一批水货才2350一对手变。9170鲍鱼全新拆车带油管一对999,也是性价比不错的选择。 GX后拨改GARBARUK腿,重量380,只比XX1重7克,比X01还轻。GX价格便宜摔了也不心疼。 ControlTech的抬升外扩瓜车吧,提供了比较少有的选项给本菜鸡。 EEWINGS纯属装犊子用的,那必然是收的二手的新的可舍不得。
