Remarkable product

On: 2008-07-26

This is precisely the product that I was looking for and didnt know it existed. My bike store did not have anything like it. It is very well built and has features that demonstrate the designers understand bike riders needs. I did have to get a bit creative when I installed the product because my bike seat wasnt really high enough above the back wheel so that the bag would clear the rear wheel. I had to put a wedge into the mounting bracket that would cause the rear of the bag to tilt upward and then I put 1/4 inch dowels on both sides of the bag above the mounting bracket which surrounds the bag. Both of those changes gave me one inch clearance above the rear wheel. There isnt any good way to know ahead of time if you will have this problem because the manufacturers web site does not provide enough dimensions for you to check your bike ahead of time. I would say that if your seat isnt raised very much, you may have this situation. Be prepared to be creative like I was or accept that you may have to return the bag. If you can get it to fit, it really is a very good product. Had the manufacturer put an adjustment onto the mounting ring, there would not have been this problem. But in spite of it, I really do like the product.

My apologies to George de Mestral

The velcro holding the bag to the cage is inadequate and has freed several times during road rides. Still considering returning this product. I would hate to consider using this with a mountain bike on rough terrain. Perhaps Ill modify this thing with some snaps.

Sleek and light with lots of room

I own two other Topeak racks with bags and this has become my favorite. I actually owned the original design for this rack made by a different company until I destroyed it by putting too much weight on the rack. You should only use this rack/bag combo if you just want to carry some extra things like a lock, a wallet, lunch, or something like that. Anything heavy or bulky - forget it - go with a regular seatpost rack. The nice thing is that with the push of a button, the rack and bag come off. Then, if I need to carry something heavier, I just attach one of my other racks on the seatpost above the fixer. Alternatively, if I dont want any weight at all, I just leave the very light fixer on the post and then attach a small bag with my pump and patch kit. If you use your bike to do everything and go everywhere, this rack bag is perfect if you want a little more room, but dont want the heavy weight of a postrack and bag.

Best saddle bag

If you are searching for a saddle bag that will hold lots of stuff ( keys,wallet,cell phone, camera, spare tube, tools,etc.) and is very durable, detaches in a second, is stylishly attractive then you must purchase this bag. I bought one last year from another vendor and am now ordering another for my daughter. People are frequently asking where I got this. Amazon price is great!!!

Great alternative to pannier

Git tired of cramming too many things into under-the-seat bags, so moved up to this gem. Holds TONS of stuff (cell phones, xtra tubes, multi-tool, energy bar, etc), and stays securely in place. Removes quickly and easily for storage. Rain cover is great too. Get one today!!
