Managed to get out this afternoon for the first time proper on the 300 and I love it!
I know I have used a lot of newer, lighter parts to build it than my 200 and when I compared them by lifting one then the other the 300 did feel lighter but not massively, but, wow, during the ride the 300 felt like it could take off, which was a bit un-nerving at times as the back end felt quite twitchy compared to the 200. Need to get it on some scales to see how much lighter it is.
It feels quite a bit longer than the 200 too, the top tube is 5mm longer on the 300, but I have a slight rise on the stem on the 200 and a 0 degree rise stem on the 300 so maybe its that.
I really like the rapid rise rear mech too, never used one before and after about 10 minutes of changing up when I wanted to change down it finally clicked and its so silky smooth.
All in all I'm chuffed with it, so glad I managed to get one in the end, it definitely feels quicker than the 200 but that might also be down to the better drivetrain fitted to it.
Here's a few pics of its first 18 miles
I met Mint out on the ride too and gave him a quick go on it for old times sake, he couldn't take his eyes off it afterwards!!!
