for most folks riding rigid is fine im sure. ITs more a case of want than need.
ive recently got a bike with a pace rc31 rigid upfront and even on 26″ wheels i dont miss the suspension – its only gonna get better on propper wheels !
taken it down rocky fast trails no bother in more ways than 1 it felt better than my 2009 sids , less flex in steering and no hand ache (although could be the carnegie bar position) but im sure id go faster with my reba upfront but for the fraction of my rides that need em i dont see the need to carry them round – just another service hungry item ! – rigid , rohloff , hardtail – very little to service !
Hope skewars on the other hand – fooking garbage – even when super tight the wheel keeps cocking when i ride hard into corners and other such things and makes a hella crack along with it !
