Description

For 2021, the DK Sprinter Series bikes solidify their place as one of Australia's most popular race bikes. This bike is designed for serious BMX racing at prices that will keep your budget on track. All the Sprinter models start with a proven 6061 aluminium frame:

Light, responsive, and sturdy enough to withstand the rigors of BMX. On the front end of each Sprinter, you’ll find chromoly forks that can handle repeated harsh landings and keep you running straight out of the gate. All the Sprinters have sealed bearings throughout, linear braking systems, and alloy cranks in different lengths to accommodate each size in the range.

From the smallest Sprinter, the Micro, sporting an 18 x 1” wheelset, all the way up to the 24” Sprinter Cruiser, each bike in the collection features size specific specifications to accommodate riders for each class of bike. The smaller bikes see narrow tires and aluminum bars, while the Pro size and up Sprinters feature chromoly bars and more tire width to carry the weight of bigger riders, at speed. In terms of performance, quality, and value, you’ll be hard pressed to find better race bikes for the buck than the DK Sprinter series.

Check the brakes and tyre pressure before the first ride

Tools: Allen key set and a 15mm, 17mm or 19mm spanner for the pedals and axle nuts (bikes can vary between these three sizes). A socket is needed if installing pegs.

Race frames are sized by class, and the class you ride is set by rider height rather than age.

Size	Rider height	Top tube
Micro (18" wheels)	Under 120cm	16.25"
Mini (20" wheels)	110 to 140cm	17 to 18"
Junior	120 to 150cm	18.25 to 18.75"
Expert	130 to 170cm	19.5 to 19.75"
Expert XL	145 to 170cm	20 to 20.75"

Pro XXL	170 to 185cm and up	21.5 to 21.85"
Pro XXXL	175cm and up	22"
Pro XXXXL	180cm and up	22.5"
Cruiser (24" wheels)	175cm and up	21.5" and up

Heights overlap between classes on purpose. Where you land in two, a growing rider is usually better on the larger, and a rider who wants the bike to turn faster on the smaller. Some brands label the Pro size Pro L, with the same fit.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark.

Between two sizes and still growing? Take the larger size.
Racing gates and wanting the bike to turn faster? Take the smaller size.
Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Not sure? Send us their height and we will tell you what we would put them on.
