[QUOTE=tk1971;16454724]Got my first Brompton (S6L).

It came with standard gearing, but thanks to the new 2013 cranks, I was able to slap a 39t Ultegra chainring for about $25 (removed 3 chain links). Now it has a similar gearing range as my MTB in middle gear (32t middle w/ 11-34t rear).......................[QUOTE]

Nice bike! It's identical to my 1st Brompton(2012). It also had the standard gearing, 50T chainring and I swapped it for the
44T chainring/crank combo from B'ton. I got the reduced gearing for my 2nd B'ton. But I still want even lower gearing for the
hills. I have a 39T Dura Ace ring on order, actually wanted a 38T but the dealer said they can't get it.

How do you like your Ultegra ring? You had to lose the protector?
