Here is a little update from Pegasus and Jason Forde. They improved Jason's Ukgrip pegs with a new taper design and added pivot caps. The caps are 15mm + base 97mm = total length of 112mm. They choose 6061 – t6 aluminium for the base and 7075 for the cap (plastic and delrin also available).
Official comment from pegasusbmx.com "Ukgrip version 2 feature smooth peg design with strong bottom new design they feature a shorter grip tape area offering a longer pivot area under the cap where the grip tape always gets warn down, the grip tape is recessed down to prevent peeling and ripping. Anodized Black blue red and polished, This new version of UK grip has a reducer washer in the base to reduce the 14mm axle hole downto 3/8″ axle hole. Cilindrical engraved to add slight grip in pivot area below the cap."
