Rated 5 out of 5 by from Very happy with purchase. I just received this rack for my Trek X-caliber. There are no mounting points on the bike for a rack so I ordered a seatpost clamp directly from Trek that has integrated mounting holes. The rack was really easy to install and required absolutely no bending of the mounting brackets. Living in Western WA I really like the integrated fender since it is next to impossible to avoid going through water on a trail ride. I won't be using the rack often for carrying gear but the fender will get a lot of use so it is very dual purpose for my application. My wife likes my bike so much we ordered one for her and I will be getting another one of these racks for her bike.

Rated 3 out of 5 by from Good - but the design work stopped short Overall a decent piece - nice welds, good finish job, etc. The versatility of the design speaks for itself (arguably all I've purchased is the rear basket, but that seems great so far) Fitment wasn't too difficult (my bike is a Novara Ponderosa) but that's where my only complaint comes in. Not the point of THIS review, but the mounts under the seat on my Novara frame are ABYSMAL - there was clearly ZERO effort made to align these things in anything resembling a single plane. This was the start of trouble mounting this rack. The pair of shiny metal brackets provided to connect to the under-seat mounts are about the least Topeak could have done. Stamped metal. In my case (and I can't believe it won't be the same in most cases) the brackets really require COMPLEX bending in several planes to truly fit well. They jut STRAIGHT forward from the bottom mounting - so unless you're lucky enough to have you seat post mounts RIGHT THERE and TWO INCHES APART be prepared for some serious bendidn'. I realize that some customization is likely to be required in most rack installs - but the mutilation required on these pieces REALLY cheapens the look of the finshed product. Short of a CAD drawing and a metal brake no one is going to have a great looking install when complete. I would also comment that I was not able to get fenders to mount - but I can't fully blame that on the rack - once again this Novara frame is proving to be less than the greatest piece if engineering in the REI catalog. I have included a photo of the clearance so that folks can see the distance between the bolts and the top of the tire. Bottom line - I'd get this again if I needed it on another bike, but I'd steel myself for the inevitable flashback to shop class required to make it fit well, and know that it's going to look a tad hacked......

Rated 5 out of 5 by from Ideal RAck This is the ideal rack for me. It fits my 29er wheels with disc breaks and is sturdy. I had to buy longer arms though as the ones that came with the rack weren't long enough to secure the rack to my frame.

Rated 5 out of 5 by from Rack for a 29 inch wheel bicycle Was hard to find a rack for this bicycle and this rack works well. Was easy to install. As a bonus I can use my Top Peak pack with panniers that I use on my other bike.

Rated 4 out of 5 by from allows easy mounting of panners Bought this rack to have the same setup across several bikes. Allows me to use the same bag setup on multiple bikes. Love the solid feel this gives to the planners. Product needs to have a mount added for securing to the seat post.

Rated 5 out of 5 by from Very sturdy This is a great rack that feels and looks very durable and sturdy and has proven to be so far. I will state that installing this is a little bit of a pain in the butt on my Cannondale, but otherwise it's great.

Would this rack (Topeak, 29er rack for disc brakes) work with a bike that uses 29+ tires (not just standard 29er wheels)?

I just ordered this rack for my Cannondale Flash 3 29er; however, I don't see any holes on the frame (near the rear hub) to use for mounting.  Is this rack compatible with my bike?

Asked by: Cannondale Don
Unfortunately, we are unable to determine compatibility with your bike. It may be best to take the bike to your local bike shop so they can assist you.

Can this frame be used to support a child seat? I have a child seat but the frame doesn't fit the ponderosa 29r 

Asked by: Lorenzo
This cargo rack works with a child seat if the child seat is designed to attach to the cargo rack (like Yepp or Topeak), and if the total weight of the seat and the child do not exceed the 55lb load limit.

I have this product. On the road, I lost one of the screws that attaches the rack to the rear axle. Where can I purchase a replacement screw?

Asked by: mfeltes
To find spare parts for the Explorer 29er Rack with Disc Mounts, we recommend inquiring with the nearest bike shop. They may have some hardware that would be an acceptable replacement. Alternatively, we would direct you to inquire with Topeak directly.

I am thinking of puechasing the San Aselmo for my wife and I was wondering if the Tpoeak Explorer would fit this frame? Thank you! V/R Greg Murakami

Asked by: ANJIN SAN
This would not be the best choice for the Marin San Anselmo as it has 700c tires. If you purchase the San Anselmo with disc brakes, the rack below will be the best choice. If you purchase the San Anselmo without disc brakes, the rack below will be the best choice.
