BLACK LABEL 309/289r XC LTD
Ringlé Super Bubba X
309/289 XC features a 30mm internal width front rim paired to a 28mm internal width rear. We have chosen a mixed width for a variety of reasons. Wider rims allow you to run lower pressure, increase traction, and add precision to your steering. However, wider rims can also result in a less compliant and bumpier ride. To avoid the later we have reduced our rims profile to 21mm. By reducing the depth, we have improved overall compliance and comfort while simultaneously offering all the benefits listed above that come with a wider rim. With most of the rider weight and power on the bike being transferred to the rear, we found a 28mm wide rim paired to 28 spokes an ideal balance between strength, comfort, and performance. On the front, we widened the rim to 30mm to add even more steering precision and sidewall stiffness where it matters most. To maintain a similar feel to the rear, we decreased the spoke count to 24 to add compliance and reduce weight for a more flickable feel while navigating the tight and twisty sections of the trail.
Reynolds MR5 with IDM
IDM is our Impact Dispersing Matrix, a combination of high-quality carbon ﬁber and a unique resin with exceptional impact dispersing characteristics. Used in our BLACKLABEL 309/289 XC and DH wheels we optimize the layup schedule to improve impact strength, tune ride quality and achieve very low weights all without sacriﬁcing durability. With durability proven on the WC downhill circuit our IDM material stands alone in its strength to weight ratio.
This wheelset has surpassed my expectations. Super light, quick engagement, and they look so damn good on the bike. I love the color of the hubs. You really can't go wrong with these wheels.
Thanks for the great review! Glad to hear we met and exceeded your expectations.
Amazing, lightweight but strong wheelset. Very quick engagement and very fast to get up to speed. Tracks very well in rough terrain.
