Hi guys, I'm looking at getting my first trials bike and I've found one semi locally in Vienna (I'm living in Innsbruck) but I'm not really sure on it's worth. The frame is a 2012 inspire fourplay. Here is a Google translation of the upgrades. 1) Inspired Flow fork, 3 weeks old (150 €) 2) Inspired Arcade High Riser Handlebar (€ 50) 3) Shimano XT brakes (4 pistons). Including new brake discs, both brakes cost € 480. Front new since July 2020, rear is less than 3 weeks old. 4) New tires since summer (Continental Danny Mc Askill Airking) (also around 150 € Also given are a couple of brand new brake pads for the XT. Is a great bike and has served me well, basically the frame is just from 2012, otherwise almost everything is new. If I were to keep the bike, I might order a new sprocket for the front (chain sprocket), but as I said, everything works fine at the moment. And a new saddle. He said he won't go lower than €1300. Any thoughts or suggestions would be rad!
