Next time I need to change my chainring, I might look at something a little smaller than the 50T I currently have.
Tried the 44T in the past and it wasn't right. So looking at a 46 or 48 if I can find the right thing.
Why? After almost a year and a half of not using my Brompton, I was in at work for a week last week and noticed how much my cadence has changed since riding a road bike in that time. Whereas I was quite happy in the past sitting in 5th a 70rpm, I've been more used to 90rpm on my other bikes.
Changing down to 4th at the same speed meant my legs were going too fast for the Brompton as it bobs a bit, so I'd like to up the cadence (a bit) so that 5th at +/- 16mph is more comfortable. I was thinking of a 48t as it wouldn't change things too drastically.
Anyone done it? Can you recommend a particular chainring? Or is is a case of any old 5 arm PCD130 will fit?
Thanks in advance.
