Riders have been asking for it, and Marzocchi heard the call and has proudly delivered. The new Z1 Coil builds on the legacy of the single-crown fork that started the revolution way back in the '90s – the O.G. Bomber Z1 Coil. Starting with the stout and proven 36mm chassis of the modern day Bomber Z1, the new Z1 Coil retains the renowned Grip damper but swaps out the air spring assembly for the most advanced coil spring system Marzocchi has ever made. At the heart of this new coil system is an ultra-lightweight tempered silicon-chromium steel spring (available in 4 spring rates to suit a wide range of riders) coupled with a noise management system for near silent performance, an integrated air assist for progressivity and bottom-out control, and an external preload adjuster to dial in sag and firmness off the top. Travel can easily be changed in 10mm increments from 150-180mm (depending on wheel size) via included reconfigurable internal spacers. - Ultra-lightweight tempered silicon-chromium steel spring (Medium Spring included) - Noise management system for near silent performance - Integrated air assist for progressivity and bottom-out control - External preload adjuster to dial-in sag and firmness off the top - Travel can easily be changed in 10mm increments from 150-180mm (depending on wheel size) via included reconfigurable internal spacers - Additional springs sold separately to fine-tune and adjust for rider preference - Rake: 44mm

HED's entire line of Big Deal fat rims can be purchased as a rim-only for the custom build of your dreams! Big Deal is 445 grams and 85mm-wide of pure fat-bike joy. This one-piece, full-carbon rim will change the way you ride. Big Deal utilizes a ribbed, single-wall design to maximize stiffness and minimize rotational weight…all on a tubeless-ready platform. Compared to most aluminum fat bike wheel/tire combinations in the market today, you can expect to lose 1.5 to 2 pounds… per wheel. Note that the Big Deal is drilled symmetrically ONLY and cannot accommodate offset frames. Big Deal utilizes Inflatobam, HED's patented tubeless technology for installing big tires. The twin channel rim design provides a better pre-inflation seal by trapping each tire bead against the rim. This drastically reduces the amount of air it takes to get the beads to “bam” into place. In conjunction with the rim shape, Inflatobam utilizes Inflatobands. These effectively provide a variable rim-channel diameter. This compensates for the discrepancies in tire bead diameters by minimizing the gap between the tire and the rim channels (the main source of air leaks). Once seated, the angled bead shelf prevents the tire from collapsing back into the rim at low pressure. Our interior surfacing and tight tolerances ensure no tire burp or slip. Also note that our rim shape does not require tire levers to remove and install tires. Inner tubes may be used, too. Additional Info - Rim Type: 85mm - Rim Material: Carbon - Rim Weight: 445g - Color: Twill Weave - Rim Hole Count: 32 - Drill Pattern: Symmetrical Only - Decal Type: White - MIN/MAX TIRE SIZE: 3.8 - 5.0" - Rim ERD: 564 (includes washer)

HED's entire line of Big Deal fat rims can be purchased as a rim-only for the custom build of your dreams! Thus far, our Big Deal fat rims and wheels have won the hearts of cyclists around the world. What if that's not enough for you? What if we told you that we now have an even BIGGER deal than before? Enter: The Big Half Deal (B.H.D.). This is a special, larger diameter version of our beloved 85mm-wide carbon Big Deal rim. With a 27.5-inch size, it's smack-dab-HALF-way between a 26" wheel and a 29" wheel. If you have a new-fangled 27.5" fat bike, this is THE performance rim choice. Like other Big Deals, the B.H.D. is tubeless ready with our patented Inflatobam technology. Tech Notes 1. Do NOT use tire levers on B.H.D. rims! 2. Specific to our Big Deal line of carbon rims: If you choose to ride these rims on regular dirt trails (e.g. NOT in soft snow or sand), wider tires and higher air pressure will decrease the chance of rim damage from striking an obstacle. We strongly recommend an honest assessment of your ride style. For the BHD, use 8psi minimum on groomed snow, or 10psi minimum on dirt and rocks - both with a minimum tire size of 3.8". Additional Info - Rim Width: 85mm - Rim Material: Carbon - Rim Weight: 465 grams - Color: Twill Weave - Rim Hole Count: 32 - Drill Pattern: Symmetrical Only - Decal Type: White - MIN/MAX TIRE SIZE: 3.8 - 5.0" - Rim ERD: 589 (includes washer)

CZR i23 gravel wheels are designed to minimize weight while blending stiffness and compliance to maximize power transfer and increase comfort. CZR i23 rims feature a 24mm section depth to maximize energy transfer, reduce weight, improve vertical compliance, and reduce rider fatigue while a hooked bead also improves tire retention with high-pressure adventure road and gravel tires. CZR I23 CARBON RIMS Reinforced spoke beds improve overall wheel strength and durability while also minimizing weight in areas where less strength, and therefore material, is needed. CZR i23 rims feature 3mm of asymmetrical spoke offset and a 24mm section depth to improve radial stiffness and maximize energy transfer without being affected by crosswinds like other wheels with deeper profiles. SOLID STRIP & TCS TAPE Durable nylon strip that lies between the rim and tubeless tape to prevent tubeless tape from pushing into the spoke holes and ensures a smooth interface between the tire and rim. The smooth surface makes it easier to mount a tire by preventing air from escaping around the bead at each indent during inflation. Solid Strip also protects the airtight system from puncture in the case of a broken spoke. 2-CROSS OR 3-CROSS LACING CZR i23 gravel wheels with 24 spokes feature a 2-cross lacing pattern to increase radial stiffness and decrease weight. CZR i23 wheels with 28 spokes feature a 3-cross pattern to increase durability while still providing ample radial stiffness due to the additional spokes. FREQUENCY HUBS The world's best carbon rims deserved to be paired with high-quality hubs that further improve the performance of a lightweight, dependable carbon wheelset. Frequency hubs feature a low-drag, 6-pawl design that alternates contact between two sets of 3-pawl groupings to provide a responsive 5 degrees of freehub engagement. Frequency hubs laced to CZR i23 wheels feature lightweight pawl springs that minimize drag and therefore improve efficiency for drop-bar usage. AERODYNAMIC WING SPOKES Pillar racing spokes that are cold-forged into an aerodynamic wing shape that reduces drag at the trailing end of each spoke. As a result, wing spokes improve overall efficiency while still retaining the gram-conscious weights of traditional bladed spokes. SAPIM ALLOY NIPPLES All CZR i23 wheels feature time-tested Sapim alloy nipples to further reduce overall wheel weight while still exceeding the durability requirements of gravel. Countless Configurations CZR i23 wheels are available in a 24-spoke option for riders looking to minimize weight and increase compliance, while the 28-spoke versions are best for heavier or more aggressive riders who prioritize stiffness and durability. All CZR i23 wheels are available with Centerlock or 6-bolt rotor mounts. CZR i23 front wheels use a 12x100mm Frequency hub, but 15mm end caps are also available separately. Why Choose CZR i23? Fast and light CZR i23 gravel wheels were designed to minimize weight and maximize compliance on rough gravel roads. With front-wheel weights starting at 620g and rears at 775g, they also deliver the greatest strength-to-weight ratio of any gravel wheelset on the market. We even stand behind them with our Ride With Confidence Guarantee for those few-and-far-between crash replacement cases.
