After a highly successful trip out on the FoD last weekend, I've just bought my 4 y-o a tagalong. It has a clamp for my seatpost, that is designed to stay attached, but I'd like to put a nylon collar into the clamp, then attach/detach the tagalong by just removing.g the seatpost from the bike and sliding the loosely fitting collar off.
So, any ideas where I can get a fairly substantial nylon collar with an internal diameter that fits loosely on a size 27 seatpost?
TIA
