With the legendary smooth and reliable DT-Swiss 350s hubs and aero spokes, these are the highest-value wheels. The larger volume tires on the 650B wheels have the same outer diameter as a 700c wheel with smaller tires. This keeps the frame geometry the same for both wheel sizes, but the 650B wheel has more tire and can be inflated to lower air pressure, which allows you to experience rough terrain with more stability, comfort, and confidence on a standard gravel bike with a drop-bar.

SAPIM Secure Lock Alloy - Black 4mm

Material: Aluminum and Polyax

Sapim has chosen the highest aluminum grade possible (7075-T6) for high-performance nipples. It combines light weight, strength, and corrosion resistance with an anodized surface. Sapim’s state-of-the-art manufacturing process ensures the best quality available. That's why Sapim’s Aluminum nipples have become the benchmark in the market. Friction between both spoke and nipple, and rim and nipple, is significantly reduced. The coating also seals the surface reducing corrosion.

Advantages:

Silent, effective truing with no more squeaks
Virtually torsion-free spokes
High-tension wheels without problems
No over-tight nipples on spoke threads
No more oily and dirty wheels
Just efficient dry working and clean hands
No unnecessary cleaning
Wheels are easier to true
Weight 0.34g/nipple

PILLAR with NYLOC

Pillar internal nipples are made of alloy material and a Nyloc coat is built into the threads to lock the spoke in place. Their convex head ensures the best possible spoke line. This prolongs spoke life, especially on today’s high-tension, low-spoke count wheels.

Weight 0.40 g/nipple

Gravel / CX and Adventure Road models
Recommended for Allroad:

WTB VENTURE 650B 47c
Venture is the set-it-and-forget-it gravel tire for riders who demand steadfast traction on a wide range of surfaces. Elevated centerline ridges and dense intermediate peaks conform to any terrain during out-of-the-saddle efforts while two rows of outer knobs provide both the support and sidewall protection you need to push it in the corners. Venture is an excellent choice when both the terrain and destination are unknown.

USAGE: Adventure Road • Gravel
