When you think of lightweight XC wheels, aluminum probably doesn't come to mind. In reality, though, high-grade alloy wheels have all of the tremendous performance properties found in carbon, like light overall weight, durability, and resilience to impact. And when made with the right hands, they're perfect for competitive racers and everyday trail riders alike. The problem is that, while many carbon wheels can check these boxes with ease, most alloy wheels don't live up to these expectations. In the case of the Control 29 wheels, however, there’s finally an aluminum wheelset that's truly ready to race.

What sets the Control 29 wheels apart is that they share many of the same advanced technologies as our carbon version, the Control SL. They adopt the same rim shape with a 25-millimeter inner width, extensive on-trail testing, and our Zero Bead Hook technology.

Our Zero Bead Hook rim takes away the dated mountain wheel design known as a bead hook. This hook is the part of the rim that crests at the top, sitting several millimeters inward from the rim’s sidewall, and it catches the tire’s bead under its hook. We know this may not sound too bad, but the hook establishes a weak spot in the rim that's easily crushed or bent. Without a hook, a rim can be manufactured to much tighter tolerances and can be made lighter due to the hook not needing to be reinforced. For these wheels, this means that we're able to nearly equal the strength of carbon, while also making them lighter than many carbon wheels. More importantly, a Zero Bead Hook all but gets rid of the aforementioned weak spot in the rim that's plagued riders with flat spots and dents for decades. If you happen to be one of those riders that enjoys riding your four-inch travel XC bike like it’s a six-inch trail bike, you’re in luck.

Our objective of low weight and reliability, at an accessible price, also carries into the Control 29 build. We hand-build each rim to our alloy hubs, which feature DT Swiss internals at the rear and a design that allows for the same spoke lengths at both front and rear, via perfectly tensioned DT Swiss Revolution J-Bend spokes and Pro Lock nipples. We fully support the art of hand-building and do so with our wheels, knowing that real people can catch things that a machine simply cannot.

當您想到輕巧的XC輪組時,可能不會想到鋁合金。但實際上,高檔鋁合金輪圈具有碳纖維輪圈的性能,例如輕巧的重量,耐用性和抗衝擊性。以人工製成,適合競技賽車手和日常越野賽騎乘。問題是,儘管許多碳纖維輪圈都可以輕鬆達到上述要求,但大多數鋁合金輪圈都望塵莫及。

Control 29輪圈之所以與眾不同,是因為它與碳纖維版本Control SL使用相同的先進技術製成。採用相同的花鼓,內部寬度為25mm,經過廣泛的騎士使用測試,並採用我們的零胎唇溝技術。

胎唇溝是位於輪圈頂部,距輪圈側壁向內數毫米(mm),並且將輪胎的胎唇卡在其胎唇溝下方。雖然可讓輪胎與輪圈緊緊相黏,但是胎唇在輪圈上容易被壓碎或彎曲。沒有胎唇溝的話,輪圈可以做得更輕。如果是碳纖維輪圈,代表能夠保留碳纖維的強度,同時比許多輪圈更輕。更重要的是,多年來一直困擾著騎士的破胎以及和凹痕發生機率也可降低。如果您是喜歡把4英寸旅行輪胎當成6英吋林道胎騎乘的車友,那麼您會很幸運擁有它。

我們以輕巧的價格實現輕量化和可靠性,融入了Control 29的結構。將每個輪圈手工編織到我們的鋁合金花鼓上,後輪花鼓採用DT Swiss internals,加上完美拉稱的DT Swiss Revolution J-Bend輻條和Pro Lock輻條頭設計,保持前後輪輻條長度相同。完全支持手工製作的藝術,因為我們知道,真實的工匠可以解決機器根本發覺的些微差異。
