Just added a thudbuster suspension seatpost to my birdie. Intended mainly for my off road birdie with big apples fitted and no racks,or mudguards. Nice and light and very comfortable. Used a Kogna telescopic post for folding bike and swooped inner for thudbuster. Bought narrow thudbuster so it can go on other bikes with shim.

Anyone recommend a double chairing guard , other than the plastic birdie one, for a 56t. Preferably metal. I have only seen the 46 pound birdie rspeed version. Surely chain rings with built in guards for reasonable prices. I want to keep with 56 gearing.
