Delivery options
How delivery works
Your item’s shipping method and price are confirmed in the shipping calculator and at checkout. Here is what each delivery path means.
Driveway freight delivery
Your equipment is palletized and protected. The freight carrier schedules delivery, then uses a liftgate to lower it to your curb or driveway. Moving it inside and unpacking it are up to you.
Inside delivery & assembly
When selected and available for your address, the delivery team brings the equipment into the room, assembles and tests it, then removes the packaging.
Full truckload
For commercial builds and multi-pallet orders, a dedicated trailer keeps the full order together in one delivery. We confirm the unloading plan before the truck ships.
Size: 63" × 34" × 83" tall
Doorways: 34" at its narrowest, which is tight through a standard 32" door, worth measuring your access
What Remanufactured Means
Every remanufactured machine is fully disassembled, deep cleaned, repaired or re-parted to factory spec, then tested under load before it ships. Backed by one year parts and labor, with extended coverage available.
Warranty Coverage
New and remanufactured equipment are both covered for one year, parts and labor, backed by us. Extended protection is available on either through BAG Care+. Used equipment is sold as-is with no warranty coverage, and is described honestly before you buy. We service nationwide - every ZIP code in the country - so coverage travels with the machine.
30-Day Returns & Exchanges
Change your mind within 30 days of delivery and you can return the machine or exchange it for a different size, color or configuration.
Return shipping is the customer's responsibility and a 15% restocking fee applies to preference returns and exchanges. Freight items must go back packaged to the same standard they arrived in. We will tell you exactly what that means before anything is collected.
Anything that arrives damaged or fails under warranty is handled separately and carries no restocking fee. Full terms are in our Returns, Exchange & Refund Policy.

CTX/ Build-a-Gym absolutely CRUSHED IT! I had been struggling with numerous manufacturers trying to get a seated leg press/extension that’d ship to Alaska. When I found CTX, they went above and beyond to get my Fractal packaged and shipped with no hassle. I HIGHLY recommend these folks to anyone looking for solid commercial quality equipment for their home.

CTX stands by their products. I recently purchased a Precor elliptical from them & it arrived with a mechanical flaw. They coordinated with a technician to get my product fixed like new. They accomplished this despite the fact that my home was two states away. Special thank you to Nichole for staying accessible and attentive throughout the process!

Absolutely best in business! Not only is Dillon just genuinely a great human being, he’s real and honest. Loved everything I’ve gotten from him and the team.

Dillion was great to work with!! Super friendly, quick turn around time, and great at communicating! The guys who delivered it Robb and JJ were also amazing. They came prepared and were very fast and efficient. They offered to help us move around other equipment to ensure we loved our gym! Super nice people and an amazing company! I would highly recommend working with them. Oh and the equipment itself is high quality and looks great in our home gym!

Rebuilt in our Jarrell, TX shop
What remanufactured means here
Every machine we sell as remanufactured goes through the same process, whatever the brand or the price. Not a wipe-down and a price tag.
-
Inspected and stripped down
Assessed frame to console, then taken apart and checked part by part. Nothing gets judged from the outside.
-
Moving parts rebuilt or replaced
Every moving and touched component, from belts and cables to bearings, bushings and grips, is evaluated and rebuilt or replaced, then the machine gets a full cosmetic restoration.
-
Refinished and rebuilt to spec
Electronics bench-tested, frames and welds checked, panels refinished, then reassembled to the manufacturer's specification.
-
Tested under load
A full operational cycle under load before it ships. Anything that fails the final check goes back through service, not onto a truck.
Get an email when new machines land
Good units go fast. We'll email you when new machines land - nothing else.

Commercial-grade equipment, inspected and supported by warranty.
The StairMaster 10G Gauntlet Stepmill delivers a revolving 8-step staircase at 24 to 190 steps per minute across 25 levels, 8"×12"×22" step dimensions, 16" LCD with single SPM adjustment, Bluetooth connectivity, and telemetry and contact heart rate - 400 lb user capacity, 646 lb commercial frame. The revolving staircase format is the defining distinction between a stepmill and a stair-climbing machine with fixed pedals: on a stepmill, actual stair steps emerge from the bottom, are climbed, and recirculate - the user is always stepping onto a new step at the correct foot height rather than pushing a fixed pedal platform down. This produces a true stair-climbing biomechanical pattern - hip extension, knee drive, and ankle plantarflexion in sequence - which loads the glutes, hamstrings, and calves through a more complete range of motion than step-based or pedal-based alternatives. The 8"×12"×22" step dimensions (8" rise, 12" deep tread, 22" wide) match commercial staircase standards closely, which is why the Gauntlet is used in first-responder and military conditioning programs. Single-step-per-minute adjustment on the 16" console allows precise intensity dialing at any point in a session without overshooting the target rate. Bluetooth enables workout tracking, BLE headphone pairing, and heart rate integration.
Handrail-mounted stop button and level controls. USB charging port. 9" step-up height. 646 lb StairMaster commercial frame, 63" × 34" footprint, 83" unit height. Remanufactured.

Revolving 8-Step Staircase - True Stair-Climbing Biomechanics
Actual stair steps emerge, are climbed, and recirculate - the user always steps onto a new step at the correct foot height, producing true hip extension, knee drive, and ankle plantarflexion in sequence. This loads glutes, hamstrings, and calves through a more complete range than step-based or pedal-based alternatives. 8"×12"×22" steps match commercial staircase dimensions - the standard for first-responder and military conditioning.
16" LCD · Single SPM Adjust · 25 Levels · 24-190 SPM
Single-step-per-minute adjustment on the 16" console allows precise intensity dialing without overshooting target rate. 25 levels spanning 24 to 190 steps per minute covers slow recovery climbs through near-sprint conditioning. Handrail-mounted stop button and level controls keep hands on rails without breaking stride during adjustments.
Bluetooth · Telemetry · Contact HR · USB Charging
Bluetooth enables workout tracking integration, BLE headphone pairing, and heart rate monitoring without a chest strap. Telemetry and contact heart rate monitoring provide two fallback paths for heart rate data. USB charging port keeps devices powered during sessions. 400 lb user capacity.
