The frame of the CREWKERZ JEALOUSY ULTIMATE trial bike is made of hydroformed aluminium alloy tubes. The hydroformed tubes give the frame an instant response to every movement of the rider and a quick return to its original position. The frame is equipped with mounts for the rim hydraulic brake using IDM adapters (4-bolts with sleeves). The CREWKERZ JEALOUSY ULTIMATE is equipped with a lightweight carbon WAW ULTIMATE fork also with attachments for the rim hydraulic brake using IDM (4-bolt with clamps). The WAW ULTIMATE carbon handlebars further reduce the weight of the bike and create a racing edge! The JEALOUSY ULTIMATE trials bike comes with a TRIALTECH Jack Carthy front brake with MAGURA HS33 calipers and a HOPE Tech 4 Trial Zone rear brake with a 160mm HOPE TRIAL disc. This trials special really brings you the best you can get on the aluminum frame cyclocross market! The unmatched quality and strength of the frame, fork and other components has been unrivaled in this category for years!
