I've decided to make a comeback to trials after about 7 years. 
 
Ive always ridden stock but am going to have a go at riding a mod and im after some mod set up advice from anyone that can help really. 
 
I've just got hold of a Onza TPro frame and now need some bits. 
 
Whats the maximum length/rise I can get out of a decent stem? and does anyone know who's making them? 
 
Also is there any cheap sealed hubs that are worth looking at? and how many clicks should I be looking at for decent engagement out of a freewheel? 
 
Cheers,
