Hi: what do you guys think of this bike and price tag? http://www.fahrrad-xxl.de/carver-pht150 A decent fork is important for me (this one has a RockShox Reba, adjustable from 80 to 120 mm). Im not very convinced about the Shimano BR-M395 disc brakes, I would rather have the complete Shimano SLX M670 groupset, which takes me to the question: How much can the price go up if I ask the vendor to change the parts from different groupsets to a full Shimano SLX M670 groupset? And another question: this fork costs, according to their website, anywhere between €470 - €602. The Shimano SLX M670 groupset can be bought at ebay for €400. A decent frame can cost... I have no idea, plus im gonna need a saddle, wheels and tires, frontset and manpower to arm it all... how much could it all ultimately cost? Would you have 29'' or 27'' wheels?
