Gurpil Zac 30 Bmx 20´´ Disc 6b Bakhjul, Silver, One Size, Shimano/Sram HG

Fordeler

• ETRTO 406 (20") with 36 spokes and Schrader valve — standard BMX sizing and serviceability
• Sealed bearings — better contamination resistance than loose-ball hubs
• 6-bolt rotor interface — wide rotor compatibility for disc setups
• 25 mm internal width and 31 mm external width — appropriate for common 1.75–2.3" BMX tires
• Low-profile aluminum rim likely offers compliant ride and easier tire mounting

Ting å vurdere

• Single‑wall rim — significantly lower impact strength and dent resistance than double‑wall BMX rims
• Quick‑release (QR) rear axle — uncommon for BMX; lower clamping strength and durability than 10/14 mm bolt‑on axles, especially for freestyle/pegs
• Critical specs not stated: rear hub spacing (e.g., 110/135 mm), driver/freewheel type, engagement, and axle diameter — major compatibility risk
• Disc‑brake rear setups are incompatible with most BMX frames (no caliper mount) and can interfere with pegs
• No stated weight or maximum system weight — difficult to assess suitability for jumps and street impacts

Oppsummering & anbefalinger

A 20" BMX rear wheel with sealed bearings and 6‑bolt rotor mount that targets disc‑equipped BMX setups. The single‑wall rim and QR axle reduce durability and clamping strength compared to typical BMX bolt‑on, double‑wall options. Due to missing hub/driver specifications and the rarity of disc‑ready BMX frames, compatibility must be verified carefully. Suitable for lighter use on compatible frames; not ideal for heavy freestyle or riders needing maximum wheel strength.

Bruksområder & tips

Best suited to riders with a disc‑ready 20" BMX frame (rear caliper mount present) who prioritize sealed bearings and standard 6‑bolt rotor compatibility for light street, pump track, or general riding without heavy pegs or big impacts. Not recommended for freestyle/street with pegs or hard landings, nor for frames without disc mounts. Verify hub spacing, axle diameter, and driver/freewheel compatibility before purchase.
