Topeak
I purchased a small bag intending to use it as a tool bag I could leave on the bike. I have a Toppeak Beamrack and found that with the rack as low as I could position it there is still not room for the bag. I kept the bag because I expect to find a use for it in the future and it looks as if it will be durable but I can't comment on how it actually performs. This is not a problem with the bag, just a compatibility issue with two add on accessories. The Beamrack has a raised bar at the front which the various baskets and bags attach to that caused the interference. A flat rack would probably allow the bag to fit, but I like the quick on, quick off mount so that is what stays for now.
I bought this for my 26" MTB. Turns out that the description is incorrect and the one advertised is for a 29". I ended up giving it to a fellow rider and bought the M1 (elsewhere) for the 26" MTB.
The fender looks great on my bike after a couple of minor adjustments to the mounting hardware to get it even with the tire. It has a lot of coverage for a 2.5" tire and keeps the spray down pretty well. I also have the M2 for the back, great fender.
The mounting bracket and hardware is OK but not optimal. A couple of size options for the frame tube would be nice as I had to trim down the tube insert to get it to fit my bike. The bracket and fender attachment points are a bit wobbly (fixed with gaffer's tape). Also, The plastic bracket where the fender attaches WILL snap off if it is tweaked against a tree just right (also fixed with gaffer's tape).
I've had this bag on my vintage Italian Steel bike for 20 years, never a problem. I just jammed it with everything i could think of for a recent bike tour, weighed it and was stunned it was over a Kilogram! The seat mount is perfect as i never notice the weight. The clip is great when I want to ride without it. I recently bought the strap mount model from BTD for my wife's ebike. The quality of the bag is still pretty great. I like that it is Aero-ish and there are several sized to choose from and the price is very good value.
