A quick calculation from my journals has confirmed that, over the three years that we have had our Ravens, Leigh and I have toured over twenty thousand kilometers on four continents on them (this excludes other cycling in between tours). The only problem we have had was when the clamp holding a Rohloff twist-shifter was broken when Leigh fell in Somerset during our tour of the UK last year - and you can't blame that on the bikes. It would be a pity if SJS were to discontinue the Raven because they are really are very reliable.
