Hey man, i got my Onza T-rex, bout 3months ago now, and what can i say, its love at first sight. For starters, i found that the bike is really light, and is complemeted well by the 'ALex' rims that come with it as standard, and the Hydraulic brakes front and rear, work so well. The stock tires are well, good, dual composite, but after a while of riding they just are like normal tires. One of the only downfalls i found, was that the shifter for the gears, 'sometimes' slips when on rocks or such, but i have got used to it, so i just left it. The frame is very strong, and overall looks great, and feels great to ride, and handles like a dream. My advice is go for the T-rex, i was in the shop, and there was the choice of a Onza T-rex , or a saracen.. i made the right choice. Just bear in mind, the money you are spending is for quality, which you get with onza. good luck with it, i reccomend the ONZA T-Rex
