Looks like I missed a good day out, however we had a great ride around Dalby the day after
Thinking of 2013 would a 1997 Marin bobcat trail with v brakes be classed as retro, it does have some 1999, shimano 9 speed parts as well, I know 97 is generally the cut of point, would this change over the years ?
A 1997 bike is ok. Post 1997 parts may encourage general tutting and comments like "it's a shame" or similar. 1997 date doesn't, and probably won't ever, change.
Seriously though, just come along, you'll have a great time, I guarantee it. Especially if Andy comes along for his first half of the ride to show off his new NOS Klein he's ruined.....
