Is it time to admit that the whole bar tape debate is just a placebo effect and the only thing that really matters is the type of grips were using on our trail bikes, or are there actual performance and comfort benefits to be had from choosing the right bar tape, and if so, how do we even begin to quantify those benefits - are we talking about grams saved, watts gained, or is it purely a matter of wrist and palm comfort, and whats the real difference between a $5 roll of tape and a $20 one, aside from the obvious difference in cost, is it just marketing fluff or is there actual science backing up the claims of the more expensive options?
