ARC MT-009F Boost Front Hub (28H, 110x15mm)
Core specs (what actually matters)
-
Boost spacing: 110mm (15mm thru axle)
- Standard for modern MTB forks
- Wider than old 100mm hubs → stronger wheel build
- Must match your fork exactly
-
28H (28 spoke holes)
- Lightweight setup
- Ideal for XC / trail builds
- Slightly less strong than 32H for aggressive riding
-
Aluminum alloy construction
- Typically 6061-T6 hub shell + alloy axle
- Lightweight and corrosion-resistant
Bearings (this is the “performance” part for front hubs)
- Sealed cartridge bearings (usually 2 bearings)
- Smooth rolling, low maintenance
- Easy to replace when worn
For a front hub, this is what actually affects performance—not engagement.
About “high engagement” (important correction)
- The listing mentioning “high engagement mechanism” is incorrect for the front hub
- Engagement (like 114 points, 6 pawls) exists only in:
- The front hub:
- Just spins freely with bearings
- No pawls, no clicking, no engagement system
Compatibility
-
Disc brake mount: 6-bolt → works with your Baradine rotor
-
Fork requirement:
- Must be Boost 110mm (15mm thru axle)
-
Wheel build:
Real-world performance
Pros
- Lightweight (~150–160g front)
- Simple and reliable
- Affordable
- Smooth rolling with sealed bearings
Cons
- Nothing “high-performance” beyond basic function
- Bearings may wear faster than premium brands
- No real upgrade feel vs other front hubs (they’re all similar)
Honest verdict
This front hub is:
???? A simple, budget Boost front hub that does its job—but doesn’t do anything special.
- ✔ Good match for your MT-009R rear hub
- ✔ Fine for XC, trail, everyday riding
- ✖ Not a meaningful “performance upgrade” by itself
Bottom line
- Your description is mostly right, except:
- ❌ “High engagement mechanism” → only applies to the rear hub
- Think of the front hub as:
- Support component (smooth + strong)
- Not a performance driver like the rear hub
