My son and I are going to build this up over the winter for him. I have alot of parts laying around, so shouldn't end up to pricey in the end. We are hoping for under 20 LBS. geared, suspension fork, big tires & a wide riser bar. Claimed weight was 1150 grams ( no size specified - probably a medium ) so I was really happy when it ended up 1030 grams with the derailleur hanger. More pics to come of some of parts I already have.
