At Base Camp Cyclery, we specialize in matching riders with the right bikes and the right components. And right now, we’re excited to announce that the SRAM Eagle 70 and 90 build kits for the Santa Cruz Hightower are officially in stock, bringing next-gen mechanical shifting to your ride, no batteries required.
When you’re buying or upgrading a mountain bike, one of the most important decisions you’ll make, outside of the frame, is choosing the right build kit. A build kit is the collection of components that makes your bike ride the way it does: drivetrain, cranks, brakes, shifters, and more. Whether you’re a trail rider looking for durability or an enduro racer chasing performance, the right combination of parts can completely transform your ride.
Let’s dig into what build kits are all about, and why the new SRAM kits are a great example of what a solid setup can do for your bike.
What Is a Build Kit?
A build kit refers to the group of components that are included on a complete bike or added to a frame during a custom build. This typically includes:
- Drivetrain (derailleur, shifters, cassette, chain)
- Crankset
- Brakes
- Wheels and tires
- Cockpit components (handlebars, stem, grips, saddle)
Most high-end bike brands, like Santa Cruz, offer their frames with a variety of build kits at different price points—each one offering a different balance of performance, weight, durability, and cost.
Why Your Build Kit Matters
Your bike’s build kit affects everything about how it rides, from shifting precision and pedal efficiency to braking power and long-term durability. It’s what turns a great frame into a complete riding machine.
A higher-end build kit doesn’t just mean lighter parts; it often means smarter design, longer lifespan, easier serviceability, and better ride feel.
Whether you’re a new rider or an experienced trail crusher, choosing the right build kit should match how and where you ride, not just what’s trendy. That’s where we come in.
SRAM Eagle 70 and 90 Built Kits: A Perfect Example of Smart, Modern Build Kits
This is where things get exciting. The SRAM Eagle 70 and 90 build kits that just landed at Base Camp Cyclery, offer a perfect example of how far mechanical drivetrains have come. Rather than relying on batteries and wireless signals, these kits bring next-generation mechanical shifting to your bike, keeping things simple, rugged, and dependable for serious trail riding.
Key Features of the SRAM Eagle 70 & 90 Build Kits:
- All-new derailleur design with SRAM’s Full Mount system for stronger, more stable performance and better shifting under load.
- Fully rebuildable derailleur, so you can service it season after season.
- Refined mechanical shifter for crisp control, especially useful on long climbs and fast descents.
- Forged aluminum cranks built for trail abuse.
- Durable steel chainring for excellent wear resistance.
These components are available as part of the Santa Cruz Hightower builds we’re currently offering, and they’re ideal for riders who want the latest in mechanical performance without the added complexity of electronics.
Why We Love Mechanical Shifting (And You Might Too)
There’s no denying that wireless shifting has become more popular in recent years, but for many riders, especially those who value reliability, simplicity, and serviceability, a high-quality mechanical drivetrain still reigns supreme.
The SRAM Eagle 70 and 90 kits are proof that mechanical isn’t outdated, it’s just evolved. You get:
- Zero battery anxiety
- Fewer electronic failure points
- Easier repairs and adjustments on the trail
- More affordable upgrades over time
In short, you get the performance you want and the simplicity you need.
Who Are These Kits For?
The SRAM Eagle 70 and 90 build kits are an awesome choice for riders who:
- Spend long days on Colorado’s rugged trails
- Want maximum reliability in all weather and terrain
- Appreciate gear they can fix and maintain themselves
- Are building or upgrading a Santa Cruz Hightower or similar mid-travel trail bike
And if you’re building up a frame from scratch, these kits are a smart foundation to start with, especially if you’re riding technical singletrack, alpine descents, or just want a bike that won’t let you down when it matters most.
