HD AXLE 26" rim wheel for single speed 110 to135mm frame drop out

Grubee Inc


Single Speed HD AXLE 26" WHEEL with 6-hole steel HUB for 6-hole sprockets, includes laced 12ga. spokes and disc brake steel hub.    

All steel axle body and hubs mean they are stronger than those made of aluminum.

This HD Axle wheel with a 6 hole solid steel sprocket hub can be used with 2 stroke pedal start bike engines such as the SkyHawk Gt5A-ES. 


 6-hole 36T to 56T Chain Sprockets are not included due to so many different sizes:  Order them separately. 

SPECS:  26" HD AXLE wheel with 12 ga. spokes with eyelets and double wall rim centered for a 135mm wide single speed frame drop out but can be adjusted for 110 to 150mm drop outs with proper technique. 

HD axle wheels can accommodate both Disc Brake attachment and can also use a Caliper Vee-Brake application on the CNC cut rim.    2 ways!  Can even use both at the same time for super-stopping power.

Comes with a steel 6 Hole CCW 36-1 screw on chain sprocket hub and spacer.    NOTE:  CCW treads are required so the drive sprocket hub does not unscrew under engine power.  

Commencing on July 15th 2021 we are now including M5 set screws on the 6 Hole CCW threaded sprocket hub to ensure the hub does not unscrew when the clutch lever is released for starting a 2 stroke engine. 

Some folks did not understand the necessity to use Loctite 271 thread lock and use the jam lock ring to securely lock the hub in place on the axle.  Therefore, so we are now adding the set screws for double securement.      Use a 2.5mm Allen wrench to lock down the set screws.

Read closely and review all the pictures.

Why would you want to buy 2 cast aluminum wheels when one HD Axle wheel matches most Vee Frame bike's front spoked wheel and can do so much more 

Keeps the original look of vintage bikes. 

  • HD AXLE 26" WHEEL with 12ga. spokes;   


  • Fits SINGLE SPEED standard 110 to 135mm drop out frames.

  • HD AXLE has (2) double row 5200 ball bearings. see pic. 

  • Our HD axle wheels come with a 6 hole solid steel 36-1 CCW screw on hub and spacer that use our exclusive 6 hole chain sprockets. 

  • (6 hole Chain Sprockets are not included due to so many tooth choices. )   Order the 6 hole sprocket you want and we will include in with the wheel at no extra shipping cost.

  • Steel hub with (6) M5 threaded holes for a disc brake rotor is included. 

    •  2 wheel rim positions to choose from.  This add is for one single speed 135mm drop out wheel.  The adjoining multi-speed wheel add has same features as single speed except the rim is spaced out to center in a 150mm multi-speed drop out.  Both are adjustable with proper spoke adjustment technique. 
    • NOTE: HD Axle Wheels avoid the troublesome and undesirable method of clamping a 9 hole chain sprocket to wheel spokes.  Clamping to spokes was never a good idea!
    •  If you are good at spoke lacing you can adjust the rim position to about any size drop out. > ie: 110mm to 155mm.   The 220mm extra long axle shaft allows custom fitting by cutting off excess length with hacksaw or angle grinder. 
    Here's what you get. 
    #1.   A double wall alum. wheel rim with 36 spokes laced to our World famous "HD Axle".    
    • HD AXLE wheel Rim has spoke eyelets found only in expensive rims.

    #5.    35-1 right hand threads on the HD axle left side are for the steel 6 hole hub used to attach disc brake rotors with M5 screws.  ( A Disc Brake Rotor threaded steel Hub is included. )   

    NOTE:   If a disc brake is not wanted you can use Vee caliper brakes as the wheel rim has a CNC cut edge band designed for Vee caliper pads. 

    Note:  To be on the safe side, Coaster Brake bikes will need to be field modified to have a rear brake system such as a disc brake,  drum brake or vee caliper brake.
