[QUOTE=1nterceptor;16466587][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).......................
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?
The 39t is good, especially for my wife when lugging the Weeride. Like I described above, the gearing with the 39t is similar to my MTB in middle gear (32t) and 11t - 34t cassette. Should be good enough for leisure / travel, which is what this bike is for.
The wife liked it so much that she commandeered the white Brompton, forcing me to order another for myself. I'm getting a black one with standard gearing. I will swap out the chain ring with another 39t Ultegra as soon as I receive it.
Yep, I did loose the chain guard. I've recently bought two 42t 130 BCD chain rings that I plan to machine the teeth off of. With longer chain ring bolts I should be able to mount it on the outside of the cranks as a chain guard. It's just a shame to grind off teeth from perfectly good chain rings. I may resort to placing a WTB ad for worn out 42-44t 130 bcd chain rings.
