Ibera Seatpost-Mounted Rear Bike Rack - Quick-Release Bike Cargo Rack for 26"/700c Frames - 22 lbs Capacity & Adjustable Length - Weather Resistant Bicycle Rear Rack, Lightweight Anodized Aluminum

I bought this Ibera rack for my high school age son, after buying a sort of generic frame mounted bike rack at a local bike shop, that absolutely failed because there was no where on the frame to mount it to, it was impossible. I returned it then came home and spent alot of time looking online at various styles of racks, to decide on this one. His cargo need is for his overladen backpack, which weighed in at 11 + pounds. This is rated up to 22 pounds. The rack itself is beautiful, great quality, well made, nice clean lines, welds, and it's very lightweight. This rack came with two sizes of rubber shims for the inside of the rack clamp which easily fastens on with an screw that tightens with an allen wrench, to fit a variety of seat post sizes. His larger diameter MB seat post required using the thinner rubber shim. I moved his under seat reflector to the end of the rack, which has space to accommodate a rear light, as well.I liked the idea of being able to buy the commuter bag that fits it, tho we likely won't. I watched a YouTube demo/review of the bag and rack in use, to check it out. I bought this also because the photos here showed it mounted on a Giant Bike, which is what he has, I was able to see what it would look like in use, mounted. It did shift a little sideways in it's first use, but it likely just needs extra tightening. I liked the larger tubing portion of the rack that forms the outside rim of the rack deck area which seems as though it will help keep anything you place there, inside and centered.Attaching the backpack securely I think will be best achieved using a small nylon ratchet or tie down strap of some sort, maybe two; one length wise, another around the rack and backpack midsection. We tried a bungee which worked OK..but I'm leery of eye/face damage and flying bungee hooks. Might send for one of the bungee nets, and see if they work. Overall, I'm very satisfied, and he likes the look of this better than the trad bike rack with frame mount, too. Mom and Kid approved. In review honesty, he has only used it once, as the bungee we used was long and impractical. Getting a heavy laden pack OFF of the back, frees up a cyclist to enjoy the ride! The seller sent this out quickly as well, I love shopping from home:-)

This is a great product! It’s built well and does exactly what I wanted. It’s a nice storage solution for a commuter that doesn’t want to use their bike just for commutes. I would not put on a carbon seat tube but for alloy you’re good. It’s one giant screw so I put on when I ride to work, then when you want to just ride with some friends takes off in 1 minute. Overall it does what you need.The only caveat is how much weight you want to carry matters. Even an alloy seat post can break, especially over time. So your 20 lb backpack is fine, but a 40-50 lb touring setup needs the support bracket.Overall great for the money!

I purchased this to use with the Ibera PakRak touring carrier. I formerly was using the Ibera PakRak Bicycle Touring Carrier Plus+, but it was big and bulky, and one of the frame bolt holes was stripped, so I thought this new carrier could solve my problem. This is easy to mount (one hex screw). Without additional support, I was concerned that it would not be stable, or hold the weight of a fully loaded commuter bag. I discovered that there are two mounting holes near the front of the rack (closest to the bicycle seat). I re-used the two brackets from the larger carrier to support the new rack better, and to prevent sway. With these extra supports, the rack is solid, stable, and strong! I don't know why Ibera does not supply these brackets, but they make this product completely reliable! The aluminum bracket is a bit short, so I ended up having to move my seat forward about an inch. If the bracket was longer by and inch or so, and included the extra two support brackets, I'd easily give this five stars! Recommended!

I bought this Ibera seat pole mounted cargo carrier along with the matching Ibera cargo bag which are both impeccably made. Excellent high quality all around. I wanted a seat post mounted carrier because I have quick release wheels on my Bianchi commuter bike and didn't want to have any attachments down at the wheels. I also wanted to be able to (relatively) quickly be able to detach the carrier when I wasn't carrying a load. Because the carrier clocks in at 1.8 pounds and the matching custom bag is also built like a tank, this is not a super light addition on your rear end. But one of the beautiful things about this combo is the ease with which the bag secures and detaches from the carrier. No need for any bunji cords or tie downs: click, click and it's done. Great design! So buying the matching bag with this carrier is THE justification for the carrier purchase. They work beautifully together. (Make sure you get the correct matching bag for this model carrier, because Ibera makes a smaller bag for a different model carrier and I don't think it will fit this carrier.)Installation is fairly simple, but be prepared; The carrier requires two metric Allen wrenches that are not supplied with the purchase (Do you hear this Ibera? You should include them.) I believe they are a 5mm for the seat post attachment and a 3 mm to slide the basket back and forth to your liking for clearance behind your seat. Easiest way to attach the carrier is to take out your seat post and slide the carrier on, then reattach you seat post, then tighten up the carrier. My slender seat post required the use of 1 of the 2 rubber shims supplied to get a tight solid fit.I tested my new rig out the other day. I packed 3 500ml bottles of water and 3 cans of cat food (I feed a stray along my route) along with wallet and keys, etc in a side pocket. It's 95 and bloody hot here in Nashville this time of year, so I always want more water than my single water bottle holder on my bike can accomodate. I also noticed that the well built Ibera bag is somewhat insulated, so I put some ice in a small ziplock bag and laid that on top of the 3 bottles of water. 2 hours later the ice was still ice and the water was still very cold. This is very impressive and not a feature that Ibera mentions. But it's a very welcome freebie!.As I mentioned, the one downside to having a well made carrier on the back with a load is it throws off the balance of the bike. It's not so bad when you're moving, but when stopped the bike can get away from you unless you're used to it. I'm so used to having a very stripped down light bike that it took a little getting used to. But, really, what's the alternative? I used a backpack for a while, which solves the weight distribution problem, but it's way too hot and uncomfortable in the summer.Ibera makes a very fine product, the best. This is the Aston Martin of carriers and matching bags.
