Owning and really liking an SL2 Raw Brompton I have considered changing the gearing of my beloved Orange Brompton to that of a 2 speed. I have even considered changing the M bars for the flat S bars. This morning I went out on the Orange Brompton for the first time in ages.
I have come to the conclusion that I will keep the Orange one exactly as as it is. To change things that drastically would be costly and just not worth it.
I have written many times about how much I love the weight, agility and simplicity of the 2 speed and the lower more sporty riding position. Cycling through London this morning I really enjoyed the very different, more upright riding position. Added to this was the fact that with a huge amount of 'stuff' to take to work, I welcomed the cavernous capacity of the C Bag.
So, I have the best of both worlds. The more leisurely upright ride of the M and the lower, firmer and sporty ride of the S.
If I change anything on my M Type it will be to the newer 110 psi Marathon tyres that really do bring a nippier ride.
