Question: I lost the 4 black screws that screw into the bike. Any idea how I can get replacements? If not, anybody know what size screws they are?
Document: The bottom rear of my bike frame where a rack attaches is 6 inches wide, so I emailed Topeak's outsourced customer support to see if this would fit. They said it should fit. When I received it, I found that it was 4 inches wide at the bottom connection points and could not fit. Topeak's customer support did not even know what the actual width was, just that "it fits most disc bikes". I've returned it to Bikesource; they've been fine.
My Novara panniers fit on the rack without modification. I am having difficulty figuring out how to mount my Vista taillight to the mount provided on the rack. I am satisfied with this rack. The reason for the 4 stars is the large size of the disc mounts and  the problem of mounting the taillight.I ordered the rack on a Saturday from Amazon and it arrived on the following Tuesday in undamaged condition. One review had complained his arrived damaged.
I installed this rack on my commuter a few weeks ago and its been getting used each day. Install was easy, bending the top brackets to fit took about 2min to get correct, all together it was about a 15min job.. I also got the MTX EXP bag for this and they work together very well. The only thing I dont care for on the rack is that the brackets that attach at the top are silver and everything else in black, a little spray paint will fix that soon.
You'll have to bend them in two dimensions.3) The hex nuts are high quality, however, I recommend you use loctite on the threads or you may lose them on the trail. Yes, this happened to us.4) When installing, read the directions, they should have a definite tilt towards the FRONT of the bike5) These work fantastically well with the Topeak MTX line of bags. We're using the DXP size (largest), which is nice mounting sys
Excellent, sturdy rack which mounted fairly easily. Nice idea with the offset mounting for disc brakes. I was happy to find this rack since the alternative for a traditional rack would have meant fabricating some spacers to get the dropout mounts far enough from the disc brakes. Typical of Topeak's high quality - very sturdy, yet still reasonably light.
This product works well with my bike that has disc brakes. It was hard to find a rack for this type of brakes. I did have to alter the installation by removing extra screw on brakes and then using supplied screw to replace from opposite side.
I have had this on the bike for three weeks along with the MTX Trunk Bag EX. So far, no problems and works like I expected. My only caution to new buyers is to take your time in the installation. The hardware is stainless and my bike frame is aluminum - it's was hard to hold the rack and screw in the fastener correctly - patience. Other than that works nicely.
These are awesome for regular bikes, but fitting one to my 29er was a challenge. I managed though, but had to use longer screws. Almost too small for the bike, but once I got it on it's fine.Otherwise, no complaints...
I purchased this bike rack together with the bike as carrier for my DSLR camera and lens for photography purpose...The black colour really matches well with my bike...it took me sometime to figure out the installation. One thing that I just want to point out is that you may need to bend the accessory brackets in order to fit the bolts. Also, the manufacturer should have just made the brackets in matte black colour rather in stainless appearance as it really gives a cheap impression look.
This didn't have enough parts to mount directly to a 2012 Diamondback XE (20&#34; frame). I borrowed some mounting brackets and screws from an old bike in order to make it work, and it's still tilted forward a bit, but not enough to interfere with attaching the Topeak bag.Using the Topeak bags with this rack is an unbelievable improvement in the bike-to-work experience.
