My next major update for Piplup is an 44-tooth chainring. The bicycle’s standard configuration comes with a 50-tooth chainring which is a little too high for me. In other words, the gearing isn’t low enough to provide a comfortable “granny gear” for climbing hills, and the common 44T switch should help with that.
I ordered the black chainring, so the silver ring part just inside the black chain-guard ring in the photo will change. I really like the look of the “black edition” Bromptons, so I am going that route with the new components, which include the chainring, fenders, and rear rack. FYI, the 2023 Bromptons have an option for black edition, but it costs more than the silver version. I would have liked to go that route, but I can’t complain since I bought my Brompton during the 20%-off sale.
