HERE WE HAVE A CARBON FRONT TRIANGLE AND ALUMINIUM REAR GT HELION EXPERT MTB FRAME IN XL. I BOUGHT THIS LAST YEAR TO BUILD UP FOR MY YOUNGEST BUT NOW A LOT MORE INTERESTED IN ALTERNATIVE SPORTS. IT HAS A HEADSET THAT IVE GREASED UP AND IS USABLE ALONG WITH SOME STEM SPACERS. IT HAS A RACE FACE BB FOR 24 MM CRANKS VERY SMOOTH. NO CRANKS INCLUDED I TRIED SOME OLD ONES TO CHECK BB SPIN. I HAVE REPLACED A PAIR OF STANDARD BEARINGS ON LOWER PATHLINK AS THEY WERE A BIT NOTCHY MUCH BETTER NOW THOUGH NOT PERFECT AS TOP COULD DO WITH A SWAP, I FEEL ABOUT USABLE AS IS. LIGHT FRAME UNDER 3 KG INC MAXLE SEATPOST CLAMP AND HEADSET. ORIGINAL BUILD SPEC CAN BE FOUND ON ISSUU. FOR SPARES POSSIBLE REPAIRS AS HAS A BIT OF CABLE WEAR ON LOWER SIDE TO CARBON +. THERE IS ALSO SOME CRACKING TO THE PATHLINK FRAME BRACKET- UNSURE IF IT AN ALLOY CASTING BONDED TO CARBON OR ALL CARBON- I CANT RECOMMEND FOR A RIDER WITHOUT REAPAIR. SO FOR REPAIRS OR SPARE PARTS. LOTS OF PARTS FOR THIS BUILD FOR SALE ON OTHER LISTINGS.
