Learn More About the 2026 Santa Cruz Hightower 4 C 90
If you want a bike that rides confidently on everything from steep descents to technical climbs, the 2026 Santa Cruz Hightower 4 C 90 should be on your radar. It balances the strength and damping you expect in a downhill machine with the agility needed to hammer through tight singletrack. The frame is Santa Cruz C carbon, so you get a stiff, responsive platform without unnecessary weight.
Up front, the FOX 36 Float Performance fork offers 160mm of travel with a GRIP damper. This fork provides plush control and sharp response when the trail gets rough or steep. Out back, the FOX Float X Performance shock keeps the suspension active over chatter and supports you through big hits. It helps the bike stick to the trail without feeling mushy.
A SRAM 90 Eagle T-Type drivetrain provides fast, reliable wireless gear shifting even while pedaling. Tt features a wide 12-speed cassette that covers every gearing need, from steep climbs to blasting flats. The 32-tooth crankset is light but sturdy enough to take abuse and keep your pedal strokes efficient.
For braking, Santa Cruz went with SRAM Maven Base brakes paired with 200mm and 180mm HS2 rotors. They deliver the kind of stopping power and modulation that build your confidence when the trail pitches downhill fast.
The cockpit shows thoughtful touches. A OneUp aluminum handlebar and 42mm Enduro stem give precise steering control. Santa Cruz’s own House Grips feel secure and comfortable. The OneUp dropper post lets you lift or lower the saddle in a second. This feature is invaluable when the terrain shifts quickly. The Cane Creek 50 IS headset keeps smooth steering without cluttering up the front end, and the SDG Bel-Air V3 saddle blends comfort with race-ready shape.
Durability and traction come from the Reserve 30|TR aluminum rims laced to DT Swiss 370 hubs. This combo handles hard riding and is easy to service. Tires are Maxxis Minions front and rear, with a sticky DHF up front for corner grip and a DHR II out back that holds on under braking and resists punctures.
This bike is built to attack a variety of trails, whether it’s flowing jumps or tight, techy rock gardens. Every piece of the build shows Santa Cruz’s commitment to tough, reliable performance without sacrificing ride feel.
