I had same question because these Controls are on sale and widely available, or at least they were last week. They appear to be made for XC use, so I passed on them. The Traverse 29 carbons for trail use don’t seem to be available anywhere.Guys I currently ride a 2020 Trek Fuel EX8 with the heavy 2100g Bontrager Line wheels. My LBS has a deal on the Roval Control Carbon 29rs that sit around 1500g. Is the $1200 investment worth the 600g savings and possibly better ride or should I save for a newer bike?
