This year’s my Easter – Converting 3-pd B75 to 5-Spd P Line Style Drivetrain weighing 10.3 kg

I spent this year's Easter modding my friend's 3-Spd B75 to 5-Spd P Line style drivetrain.

Key mods:

– Swapped rear triangle to original Brompton titanium one

– C Line style H&H tensioner with ceramic axle pulley (yes a bit of an overkill but had one lying around)

– Suncord C Line style derailleur

– SRAM GX 11-Spd Shifter

– Increased chainring size from 44T to 50T cuz another friend suggested that 44T may lead to skipping

– T Line rims; custom anodized to silver

– Brombacher/Hubsmith 4/5-Spd rear hub and front hub

– Swapped from original pre-2017(?) M-handlebar to post-2017(?) M-handlebar

– Swapped from original pre-2017(?) brake levers to post-2017(?) brake levers

– Titanium seatpost from Ali

– Swapped to P Line saddle

– Reduced weight down by 2kg (4.4 lbs) from 12.3kg to 10.3kg

Sent pix to my friend and think he is very happy.

Had fun with an interesting project and time well spent.

Hope this helps whoever is thinking of something similar.

Happy Easter everyone!
