Had a soul years ago which was good .went back to FS then got pink 456 and did not get on with it at all . Then many years later got a cheap 2nd hand old inbred / 456 and loved it so much so I now have got me a 456 evo 2 . And that’s even better as it sits half inch lower BB and steeper ST with a slacker HA = Fun fun
Mate has got a SS 456 and says its was like a gate of a bike and felt like one ( now has a slackline)
So go for the std 456 evo 2 and save some cash or just go for Ti .
Ps evo 2 comes in at 5 half pounds all above was 18″ frame .
Hope this helps
