Wheel rim for e-bikes and heavy-duty cycling, promising a sturdy foundation for demanding wheel builds. Riders who carry cargo or tackle steep trails gain confidence from robust construction and spoke compatibility. Is the hammer-ebikes MTX39 Double Wall Downhill e-bike Wheel Rim the right choice for tougher, longer-lasting wheels?
⚡ At a Glance
- • Construction: Double-wall design for greater strength and rigidity
- • Best for: E-bikes, downhill riding, tandems and cargo/delivery bikes
- • Not ideal for: Wheel builds requiring other rim diameters or non-12G spokes
26-inch rim designed for 36-spoke wheel builds with compatibility for 12G spokes. Intended use includes e-bikes, downhill, tandem and delivery applications, with double-wall construction for tougher riding conditions.
Stiffer wheel builds - thanks to double-wall construction
Double-wall construction uses two rim walls to increase lateral stiffness and distribute impact forces across the rim cross-section. Higher stiffness reduces flex under load and helps maintain true over time.
More predictable handling and fewer spoke adjustments on rough terrain. Heavier riders and cargo racks benefit from a rim that resists deformation during hard use.
Reliable lacing options - with a 36-hole layout and 12G spoke compatibility
A 36-hole rim supports common lacing patterns that balance strength and tension, while compatibility with 12G spokes accommodates a thicker gauge suited to heavier loads. The combination suits robust wheel builds for demanding applications.
Wheel builders can choose sturdy spoke patterns and thicker spokes for load-bearing wheels. Expect a durable wheel that copes better with sustained weight and torque from e-bike motors.
Built for heavy-duty riding - with downhill and delivery focus
Specification highlights suitability for downhill, tandem and delivery roles, indicating a design intended to withstand repeated impacts and continuous load. The focus on these uses implies reinforcement where strength matters most.
Suitable for riders who frequently carry cargo or ride aggressive terrain, where rim resilience matters. Longer service life and fewer maintenance stops are realistic benefits for heavy users.
