    handcycle racing regulations

    I have been searching for a set of handcycling bike regulations for some time. I am having a custom bike built and I need to clear some things up. Does any one if there is a standard set of regulations? I am specificly interested in drive hubs. I would like to to use a Rohloff internal gear hub. I know that it has 14 gears and if I ran a dual chainring at the dottom bracket it would give me more gears than the standard gear set up would have. I am planing on just running 1 drive gear. Any info would be helpfull.

    Thanks

    Here's the regs from the US Handcycle Federation. PDF link The main classifications are the level of injury.
    HC 1 - Tetraplegia or other mobility impairments without tricep, finger or thermo-regulatory function(s). May
    include SCI C1 - C6.
    HC 2 - Tetraplegia, Paraplegia or other mobility impairments with limited tricep, finger or thermo-regulatory
    function(s). May includes SCI C7 through T3.
    HC 3 - Paraplegia & other mobility impairments with limited trunk stability. May include SCI T4-T8.
    HC 4 - All others, to include SCI T9 and below, cerebral palsy, amputees, etc.
    Main handcycle restriction.
    A handcycle is defined as a 3-wheeled cycle with a standard bicycle drivetrain and standard bicycle
    crankarms. A handcycle must be operated by pedaling, shifting, braking, and steering using ONLY the
    upper body to perform said functions. The maximum wheelbase for a handcycle is 65 inches.
    Handcycles with a drivetrain operated by a mechanism other than standard bicycle crankarms, or
    handcycles with only two wheels are not recognized as "legal" equipment as stated in the definition
    above. All handcycles operated in IPC cycling events must have a guard to protect the rider from the
    outer chainring on the crankarm.

    For road races, your custom bike will need to have a rear draft bar.

    I have been working closely with the USHF on each individual item I am proposing. Thanks for all the help.

    Well my Bike is in the full scale drawing stage. The builder has been working with the UCI and the Handcycling Division to get some things approved.

    I pose a question to you: what is your thoughts on this statement " shifting controls have to be within the extremeties of the crank arms "

    My take on this statement is the the shifter has to somewhere "between" the two handgips. Using my interpretation the shifter does not have to be mounted on the grips it can be frame mounted somewhere between the crank arms. I am trying to eliminate all cables from both hand grips since I ride mostly open roads but I want to still be within the guidlines so I can compete at santioned events.


    I would apreciate your thoughts on this.



    Also we have not heard back on the use of a carbon drive system. I don's see why there would be an issue since the belt is completely sandwitched between two plates and this makes it virtualy impossible to get your fingers stuck on them. This would eliminate the use of a hard mounted sprocket guard. Thoughts?



    Thanks

    Yes, the shifter can be mounted on the frame or fork within reach. Some people have their chainring and derailleur shifters mounted on the front fork within finger reach when the crank arms are forward.

    I was planning on runing my break levers out there any ways so this will help keep everything clean and functional. Since am using a Rohllof hub and an elctronic shifter The lag in shifting will be obsolete while not moving the crankarms.


    Thanks.
