Profile Racing – Why the Z Coaster?

Yesterday, we got a look at how the slack cam rings work on Profile Racing’s Z-Coaster, now we have two videos featuring Chad DeGroot explaining how the Z-Coaster works! There’s also some flatland riding from Chad putting the hub to good use to go with it. No word on exact release, but Profile Racing said this is the month, so keep your eye out if you’re on the hunt for one.

They have even released a video showing you how to change the slack cam ring which gives the first look INSIDE the hub since that has been top secret until now… Even the samples the team riders are on are welded sealed so they couldn’t open them!

igiBMX release Nylon Caps for the Microphone Peg


If you ride indoors, one of the problems you will face is the bike dropping and scratching the floor. This can be the difference between keeping the spot and losing it, in order to take full advantage of riding indoors. Dub has just released these new nylon caps for the Microphone Peg that if you use a full set will knock 4.5 oz in total for all of you who are weight conscious, but more importantly keep your indoor spot smoother and scratch/dent free. 21 grams a cap and are sold in pairs.

Plus in related news, Dub’s also making spacers to make the pegs longer for all of those with bigger feet, contact Dub via the site for more details.
