A 17-inch mountain bike frame can suit riders looking for a medium-size build, but wheel size, suspension, and component standards matter just as much as frame height. The DHNCBGFZ and YFGSFWTS hardtails are options for simpler 27.5- or 29-inch builds; HWEVDHJ lists a wider tire range; and Gravity and YFGSFWTS offer full-suspension designs. Compare the specifications below with your existing parts before choosing, since standards such as seatpost diameter, rear spacing, and bottom-bracket type vary.
| Frame | Style | Standout listed specification |
|---|---|---|
| DHNCBGFZ 27.5/29er | Hardtail | 135mm quick release; tires up to 2.25 inches |
| YFGSFWTS 27.5/29er | Hardtail | Approx. 1,740g; 135mm quick release |
| HWEVDHJ 27.5/29er | Frame listing does not specify suspension | 27.2mm seatpost; tires from 1.50 to 2.35 inches |
| Gravity FSX 29-inch | Dual suspension | Adjustable rear shock included |
| YFGSFWTS 27.5-inch | Full suspension | For a 165mm rear shock; tires up to 2.4 inches |
DHNCBGFZ 17-Inch Hardtail Frame
This aluminum-alloy hardtail is listed for 27.5- or 29-inch wheels and uses a 9x135mm quick-release rear end. The specifications include a 44x44mm straight head-tube standard, 31.6mm seatpost, 34.9mm seat clamp, and threaded BB68 bottom bracket. The stated tire limit is 2.25 inches.
Best for: Riders building a straightforward hardtail with components that match those standards. It was selected for its clearly stated fit dimensions and wheel-size options. Limitation: The tire clearance is listed up to 2.25 inches, so it is not the pick for a wider-tire build.
YFGSFWTS 17-Inch Alloy Hardtail
This rigid 17-inch frame is listed for 27.5- or 29-inch XC/enduro builds. Its stated standards include a 44x44mm straight headset, 31.6mm seatpost, 34.9mm seatpost clamp, threaded BB68 bottom bracket, and 9x135mm quick release. The listing gives an approximate frame weight of 1,740g and tire clearance up to 2.25 inches. It also specifies a disc-brake mount.
Best for: Buyers prioritizing a hardtail with detailed component dimensions and a listed frame weight. Limitation: Confirm the 2.25-inch tire limit and quick-release spacing meet your build needs before buying.
HWEVDHJ 17-Inch Multi-Wheel Frame
The HWEVDHJ frame is described for 27.5- or 29-inch wheels and has a 17-inch center-tube measurement. Listed specifications include a 120mm head tube, 44mm headset, threaded 68x34mm bottom bracket, 27.2mm seatpost, and 135mm quick release. It supports tires from 1.50 to 2.35 inches and is listed as compatible with hydraulic or cable-actuated disc brakes.
Best for: Builders who want a wider stated tire range than the two hardtails above or need a 27.2mm seatpost standard. Limitation: Its seatpost diameter differs from the 31.6mm standard listed for the other hardtails, so check component fit carefully.
Gravity FSX 17-Inch Dual-Suspension Frame
This Gravity FSX frame is specified for 29-inch wheels and is described as a 17-inch medium size, with a listed rider-height range of 5 feet 10 inches to 6 feet. Features include disc-brake mounts, a replaceable derailleur hanger, and an adjustable rear shock. The dual-suspension layout makes it a different choice from the rigid hardtail options in this list.
Best for: Riders seeking a 29-inch dual-suspension frame and a frame listing that provides a suggested height range. Limitation: The supplied specifications do not give detailed component standards such as seatpost diameter or rear spacing; verify fit before selecting parts.
YFGSFWTS 17-Inch Full-Suspension Frame
This aluminum-alloy frame is listed for 27.5-inch wheels and XC, downhill, all-mountain, or freeride builds. It uses a 135mm quick-release rear end, has a stated approximate weight of 2,755g, and accommodates tires up to 2.4 inches. The listing calls for a 165mm rear shock, specifies a threaded 68mm bottom bracket, and gives a 30.4mm seatpost size.
Best for: Builders looking for a full-suspension 27.5-inch frame with more stated tire clearance than the hardtail choices. Limitation: It requires a 165mm rear shock, and the listing describes a 30.4mm seatpost; confirm both before sourcing components.
Buying Guide: How to Choose a 17-Inch Mountain Bike Frame
Does 17 inches mean the same fit on every frame?
No. The 17-inch measurement alone does not establish fit. Frame geometry and the rider’s proportions also affect fit, while the Gravity FSX listing specifically suggests a height range of 5 feet 10 inches to 6 feet for its medium frame. Treat that as product-specific guidance, not a universal sizing rule. Check the frame’s geometry details and compare them with a bike that fits you.
Which wheel size and tire clearance should you choose?
Match the frame to the wheel size you intend to use. The listed hardtails offer 27.5- or 29-inch options, while the YFGSFWTS full-suspension frame is specified for 27.5-inch wheels and the Gravity FSX for 29-inch wheels. Tire limits vary: the hardtails list up to 2.25 inches, HWEVDHJ lists up to 2.35 inches, and the YFGSFWTS full-suspension frame lists up to 2.4 inches.
Which component standards need checking?
Compare the frame’s rear spacing and axle type, headset dimensions, seatpost diameter, brake mounts, and bottom-bracket standard with your intended parts. For example, these listings include 135mm quick-release rear ends, multiple seatpost diameters, and threaded BB68-style bottom brackets. Similar wording does not guarantee that every component will fit; confirm the exact dimensions and standards before assembling a bike.
Should you choose a hardtail or full suspension?
A hardtail has a rigid rear end and fewer suspension-specific parts to match. Choose one if its standards suit your build and you prefer a simpler frame layout. A full-suspension frame adds a rear shock requirement: the YFGSFWTS listing specifies a 165mm shock, while the Gravity FSX listing says an adjustable rear shock is included. Check what is included and which shock dimensions are required.
Frequently Asked Questions
Is a 17-inch mountain bike frame a medium?
Some listings label a 17-inch frame medium, including the Gravity FSX listing. Frame labels and fit can differ, so use the product’s geometry and rider guidance rather than relying on the size name alone.
Can a 17-inch frame use either 27.5- or 29-inch wheels?
Only when the frame listing specifies those wheel sizes. Several frames here list both options, but the Gravity FSX is listed for 29-inch wheels and the YFGSFWTS full-suspension frame for 27.5-inch wheels.
Are these listings for complete bikes?
The product names and specifications describe frames. Read each listing carefully to confirm exactly which parts are included; a frame listing should not be assumed to include a complete bicycle build.
Will a 31.6mm seatpost fit every frame here?
No. Listed seatpost sizes vary: some frames specify 31.6mm, HWEVDHJ specifies 27.2mm, and the YFGSFWTS full-suspension frame specifies 30.4mm. Match the post diameter to the frame specification.
