Overview
This is a bare 29 inch mountain bike hardtail frame, sold without wheels, fork, or drivetrain. It is built around a 12x148mm Boost thru axle rear end with post mount disc brake tabs and comes in M or L sizing for riders assembling or replacing a hardtail.
The frame uses welded aluminum alloy tubing finished in a glossy lacquer, with fully internal cable routing so housing runs through the tubes instead of along the outside. At roughly 2250 grams it is a frame only kit aimed at someone already sourcing a fork, wheelset, and groupset for a build.
- 12x148mm Boost thru axle rear end
- M/L sizing keyed to seat tube length and rider height
- PM74.2mm post mount disc brake tabs
- Glossy lacquer aluminum alloy build at about 2250g
Who it's for
Riders assembling a custom hardtail or swapping a cracked or outdated frame, who already know how to match a fork, wheels, and brakes to a given frame spec. Not for someone who wants to unbox a complete, ready to ride bike.
Pros and cons
- Lightweight aluminum alloy frame at about 2250g
- Full internal cable routing for shift and brake lines
- Works with a standard 31.6mm seatpost and 44/56mm tapered headset
- Includes derailleur hanger, thru axle lever, and seatpost clamp
- Frame only, no fork, wheels, or groupset included
- Requires matching Boost-spaced wheels and PM74.2 brakes
- Sizing tied to seat tube length, not just height
Performance notes
Sizing runs by seat tube length rather than a single number: M measures 430-440mm and suits riders roughly 165-175cm, L measures 475-480mm for riders roughly 175-185cm. The frame accepts a 31.6mm seatpost, a 44x56mm tapered headset, a BB73mm threaded bottom bracket, and tires up to 29x2.35 inch.

Frequently asked questions
What size fits a 175cm rider?
Bsfhqs lists M for 165-175cm riders (seat tube 430-440mm) and L for 175-185cm (seat tube 475-480mm), so a rider right at 175cm sits at the boundary and should compare against a current bike's seat tube length before ordering.
Does the Bsfhqs frame include a fork or wheels?
No.
What tire size does this frame clear?
It is rated for tires up to 29x2.35 inch.
