I can not say nearly as much of this double pedals. I bought it there are few ready 5-6 months and I still discovering!
Of course, this is my first double pedals but the comfort and the many possible rglage ca either at the hardness with the Systm powershift and the angle of the chain (the hammer). All this makes up what MRIT ca!
The only problem that I think it could have is a problem in the chain is too small for my taste surment so fragile!

Regarding the price quality RAPORT I think what the market has qur 232 euros which dja rsonable a price.
