We tapped into everything we’ve learned from years of making the highest quality carbon full-suspension bikes and added the super-efficient Superlight™ suspension to make a World Cup-winning XC race bike. The Blur isn’t guaranteed to make you a race winner but being the lightest, full-suspension carbon XC bike we’ve ever made, it might be the difference between claiming first place...or just crossing the line.
FEATURES:
- Eagle 90 Mechanical Transmission: With ultra-refined T-Type architecture, it delivers flawless shifts under full power and ultimate durability. Lightweight materials, premium construction, hangerless design, and pro-level precision—Eagle 90 is the gold standard of mechanical shifting.
- XC or TR: The TR builds feature more travel (115mm rear, 120mm front) slightly beefier tires (Maxxis Rekon), a full height adjust dropper post, no lockout remote, and larger brake rotors. It's not a trail bike, it's a XC bike for certain courses.
- Light Carbon Frame: The full-suspension Blur is lighter than most pre-race dinners you'll eat - 289g saving over previous generation.
- Geo to match: The Blur's chainstay length is matched to frame size so every rider, no matter their height, gets the same balanced geometry and bike fit.
- Two water bottles: Two water bottle mounts within the front triangle mean there's enough juice (or whatever electrolytes you choose) to keep the engine running.
- No proprietary gubbins: There's no fiddly proprietary parts that could leave you stranded in a Cape Epic or Breck Epic campsite.
- Made to last many lifetimes: The legendary Santa Cruz fit, finish and quality construction put this into a league of its own. The frame, bearings and optional Reserve wheels come with a lifetime warranty and any service is easy to do with our Rider Support pledge.
- Chainguide: The only thing you'll be dropping is your competitors

Well made and perform well, a little constricting
Size: Medium, Color: Black Assortment (6-pairs)
These socks definitely keep most of the moisture away from my feet, even in wet conditions, which is why I bought them. I am diabetic, though, and the recommendation is to wear socks that don't constrict at any point. These have a tight band around the opening that while it is not uncomfortable on, leaves a mark when I take them off. So far it's been ok, but if you have any kind of swelling in your feet or ankles these would probably not be the best. My foot measures size 8 and I wear size 9 Brooks running shoes. The socks fit me just right but based on the size of the opening and the overall length, I wouldn't think they would fit anyone more than a size larger. Overall well made and perform well as you would expect from this brand.
