sizing for mountain bike
All the charts put right in the middle between 14' 16' frames. I've ridden 14s and 16s and they both felt fine (but I think I might have needed a slightly longer stem on the last 14 I can remember b/c it had a really short one) I like just kind of chilling on MTBs; riding upright and taking in the scenery. I also like longer casual rides rather than hard riding. But I'd like to actually do some group trail rides this year. Is it better to go down a size or up a size?
What's the difference really long term? Seems like a larger frame might be more stable for descents but that's all I can figure.
