What Diameter Seat Tube Will The Fitting Go To ?
15 Sep 2015
SJS Customer Service:

This Topeak seatpost mounted bag can fit to seatposts anywhere between 25.4mm and 34.9mm in diameter.

Would This Fit Onto The Down Tube Of A Tricycle.
09 Jan 2015
I am looking for a bag to fit to the down tube (not the seat post) of an upright tricycle. I want to fit it low on the tube below the seat stays, to keep the weight low. I have just bought a 16 L carradice bag from you, unfortunately although the attachment rings are large enough, they will not open out to fit on the frame. How does this bag attach? Will it fit onto a dwn tube? Can the bage easily detatch to be carried.

Although this bag can be easily removed from the bracket to be carried separately the fitting of the bracket will prevent it from fitting on the down tube of your bike. The bracket is bolted to a metal band style clamp which has no opening as such and has to be passed on over the end of a seatpost normally.
