Empty Roller Drums
Filled Roller Drums

    Dynolight Rollers® were designed following a request from British Athletics in 2015.   They required race chair training rollers suitable for air travel to the Rio Paralympic Games.

    Portable training rollers were needed that would work effectively but be light enough to avoid airline excess baggage costs. For training rollers to work well they need to provide momentum to the wheels of the race chair.  The roller drums’ weight provides this momentum, so by their very nature training rollers tend to be heavy.  To resolve the weight versus momentum issue we incorporated fillable roller drums into our design.


    Two versions available

    Standard aluminium weight = 5.5kg

    Carbon fibre weight = 4.9kg


    Weights are based on empty drums and include a front wheel stand.


    By filling either one pair or both pairs of roller drums with kiln-dried sand the overall weight can be increased by up to an additional 8kg.  Each pair of roller drums will hold up to 4kg of kiln-dried sand. Filled roller drums will result in an easier training session than leaving all four drums empty.


    Some static single drum training rollers weigh in excess of 60kg, these will always have more momentum than portable versions due to the inertia of the rotating drums’ mass.  However, since launching Dynolight Rollers® feedback suggests some athletes actually prefer lighter drums as they don’t “run away from them”.  In other words, when the athlete is up to speed more effort is required to keep the rollers going at a constant velocity.  Empty rollers make it a harder but more effective training session - the choice to fill them is yours.


    If the rollers are going to be left in situ, for example during winter training most athletes keep them filled with sand.  Then in the summer racing months when being transported to events, they remain empty for portability.


    Both versions are light enough to take anywhere; outdoor track events in the summer and indoor training all year round.  They are perfect for use at competitions if there is no warm-up track available, or even if there is, take Dynolight Rollers® along for a more comfortable warm-up in the shade!


    As Dynolight Rollers® are of modular build they can accommodate race chairs of: any width, any size wheel, any track width* and any frame design.         *The distance between rear wheels at ground level.

    In the case of a child, replacement middle tubes can be purchased later to reflect the change in race chair size as the user grows.


    Dynolight Rollers® are shipped semi-assembled so no specialist tools are required to get your training started.  Connections are made with thumb screws.   Complete dismantling to fit in a rucksack with room for a helmet, gloves and water bottle will require a 5mm allen/Hex key.


    Why we use a stand...

    The pair of roller drums at each side of our sets are positioned much further apart than similar equipment on the market; meaning the race chair sits in a trough between the rotating drums rather than on top of them.   By incorporating a trough into the rollers’ design, it is gravity that holds the race chair down rather than a bulky and heavy clamping device attached to the end of a front wheel stand.

    As our aim was to make training rollers as lightweight and portable as possible, you may be wondering why we still use a front wheel stand at all...  If you have ever pulled a racechair along by lifting the front wheel off the ground you get a very unpleasant effect on the rear wheels called tyre scrub.   When the front wheel is either higher or lower than the rear ones the angle of the rear wheels is not parallel with the point of contact on the ground, which causes friction.   The same ‘scrubbing’ effect is seen on most training rollers if a stand is not used; not only creating an inefficient work-out for the athlete but prematurely wearing expensive tyres and leaving a rubber trail behind on the rotating roller drums.


    We use a very simple front wheel stand to raise the height of the front wheel, alleviating the problem of tyre scrub but not adding unnecessary weight to the overall product.


    We hope you agree our design means there is no compromise on weight, function or portability.
