Mod ideas..
The new spider crank & BB would be 1 nice replacement allowing a 39t chainring.. Or their 44, 50 or 54t
More gears , faster shifting, a Schlumpf Speed drive with 110 spider & 34 t chainring integrates its own BB, and has a 2nd overdrive internal gear ,
as if a 54t
left pedal core can be replaced with a Titanium one,
Or even the new steel ones save weight over the big 24mm hex bolt head solid ones..
I got a few of the Fizik for Brompton QSADVIT -A lightweight saddles.. which are a version of their Vitesse HP with a different steel rail bend
room for the pentaclip above the saddle rails ( from a now closed dealers' stock..)
A Brooks C 17 all weather would be more durable ..(but weigh more an have no padding , they use rubber instead of leather.. suspended between nose & tail..
& of course you have their front bag selections to explore , + Carradice makes a nice bag using their classic materials,
that slips over the B bag support frame , bought separately..
Ergon GC 2, 3, 4 are progressively longer integrated bar ends I use the 3 on my M3l Brompton..
