Soloist sits right between S5 and R5 on the performance scale, while having a price tag that’s less World Tour, more Road Trip. It’s about 250g heavier than R5, and 250g lighter than S5. It’s 190g slower than S5, but 126g faster than R5. You get the idea. It’s the ‘just-right’ answer for the rider trying to find a smart, intentional compromise..
