The specification of the aluminium track frame dimensions and geometry can be viewed here
The Pure youth track frames are hand made in Italy using 7005 series aluminium. The frames feature a rear wheel hugging seat tube to reduce the air drag around the rear wheel to make for a more efficient frame.
The frames use the internal headset that is used on all our frames we use the large 45/45 headset that reduces flex when you are up out of the saddle sprinting for the line on the velodrome.
The drop outs include stainless steel inserts that help to reduce wheel slip and also increase the life of the frame. The track frame is a no compromise frame using large section rear chain stays so that no power is lost in the frame.
The youth frames are made to the same spec as the adult frames there is no difference apart from the size. The youth frame allows the younger rider to be able to really enjoy the Velodrome as they will be in total control of the frame and not stretching for the bars.
If you want the edge, choose Pure!
