its the sig frame the one ridden by Martin Hawyes if you google giant team trials you'll see my frame setup for trials, how stupid can you get the frame says it down the side in bright yellow writing what did giant design it for xc, not, just jealous your bike dont look that good, the only difference is that mines a newer version as on the original the brake mount kept snapping, and yes the geo is a bit different for trials but thats why i got it, its different and i like to try new and exciting things, bin out all day, did the 20 footer again well about 5-6 times ask nova666 he was there,
