Question: can this fit a bike with rear disc brakes?
Document: Poor quality of both design and implementation.Screws have bad threading. None of my Allen keys fit the head. Had to run to the Home Depot to get better bolts.It is not universal! Once installed it gets on the way of the disk brakes mechanics. It tights the brakes and make the either squeak or stock in breaking position.
I like the fact that you can configure it to fit almost any bicycle, truly a universal fit. I would recommend this if you need a rack for a bike thats difficult to find a rear rack to fit.
This rack is garbage. Mine was poorly welded and poorly bent, so it wasn't even close to straight. Then it simply wouldn't fit on my bike over a rear fender. Even before I took it off though, I was chuckling about what a dope I'd been to expect something so inexpensive to do the job.
Its a good thing I had some extra hardware laying around. The screws it came with needed nuts and don't fit in to the pre-tapped holes of the bike itself and there was no bolt for the part that bolts the front of the rack to the rear brake bar. Save yourself the trouble and buy a pre-assembled rack.
Great rack.. fit my Schwinn perfectly, but I had to remove the rear wheel to get the bolt on the side with the sprocket...  this is probably a feature of all these types of racks and is more of a problem with the design of the bike than the rack...  but I wasn't prepared to undertake such an operation... I should have taken it to the bike shop and let them install it...
My concern was that it would not fit over a tall tire but it did. The brackets all fit well on the bike. No modifications were needed.I just wish they would have included a couple more screws and nuts to compete the job. It was short screw & nut. Also I have to figure out or make an additional bracket to relocate my rear light as it is blocked now with this addition.
This could be IMPORTANT as my wife's bike frame was threaded to this exact size. Bigger wouldn't have fit and smaller is less sturdy! This is the same size as the hardware that came with the rack. All in all, the replacement mounting hardware cost about $5 so even then the total cost was still comparable to the other rear racks out there. Overall study and a nice low price, it just loses that one star for the mounting hardware.
Please watch this video first to determine if the rear rack you are buying will fit on your bike.[... ]For my bike I needed a seat post adapter. (realized it AFTER I bought the rack). It is not easy to get a seat post adapter like the one mentioned in the video. S I went to performance bicycle and special ordered it from their catalog. Took 5 days. . Once done it is easy to install this product.
OK, it came without instructions...But after figuring out how it mounts to the bike, I was able to install it using the supplied hardware  I did not need to use the extension arms, so I had 2 screws and 2 nuts left over.The front mounted to the bolt that holds the rear brake calipers and the lower arms fit 2 pre-threaded holes on the frame near the rear drop-outs.It seems heavy-duty and durable. I'm very satisfied with this purchase.
This item is not as universal as it claims and I would warn anyone thinking of buying this to consider spending the extra $20 to purchase a better built rack from a popular manufacturer. This thing requires more assembly than the major models, and it will not fit a disc-brake configured bicycle. It is also considerably heavier than some of the other major players - despite being spec'd for carrying a similar weight load. Save yourself the fuss and avoid this one.
Answer: yes
