Ibera Bike Rack - Bicycle Touring Carrier Plus+ for Disc Brake/Non-Disc Brake Mount, Fat Tire Bikes, Frame-Mounted for Heavier Top & Side Loads, Height Adjustable for 26"-29" Frames

Good rack, not designed for bikes with Boost rear axle spacingI knew when I bought this rack that it was designed for the ‘standard’ rear axle spacing of 135mm that is used on bikes with 9mm quick-release skewers, and not the newer ‘Boost’ rear axle spacing of 148mm that is used on most modern mountain bikes that have 148mm x 12mm thru-axles. What that means in practical terms is that the cylindrical spacers provided are twice as long as necessary when the rack is used on a bike with Boost spacing. These spacers are 7/8” long and made of aluminum so they are very easy to cut if you are comfortable with that sort of thing. I simply cut one exactly in half and that made the width of the rack a perfect fit for the mounting lugs on my bike. Shortening the spacers required me to also grind down the length of the provided mounting screws to match the shorter rack+spacer dimension. You could simply go to the hardware store and buy shorter machine screws, but it was easy for me to just grind the provided screws to the length required.There was one other fit issue that was due to the frame geometry of many mountain bikes. The provided front carrier mounting arms were too short to work on my mountain bike. In general the angle of the seat tube mountain bikes use is quite a bit steeper than what was used in the past. The end result of that geometry is that the top rack mounting lugs on the bikes frame are a bit farther forward on the bike than older design bike frames. My bike is a 29er and that also stretches out the length of the bike a bit due to the larger wheel and tire. Bottom line is that the provided front carrier mounting arms are too short. To their credit Ibera does sell longer front carrier mounting arms on their US distributors website and they are a reasonable price. One other small bit of information that may be helpful to anyone trying to order the right parts is that the chainstay length of my bike is pretty short, 440mm. Before I had the actual rack in hand to check the fit, I hoped that short chainstay length might allow me to squeak by with the provided front carrier mounting arms. Even with that fairly short chainstay the arms were still too short for my bike. My guess is that any 29er with longer chainstays would also require the accessory longer front carrier mounting arms. I also bent the carrier mounting arms to match the radius of my tires just because I thought that looked better.I bought the rack knowing that I would have to do a bit of work to make it fit my bike properly. As far as I could determine at the time I bought this no company makes a rack that is specifically designed to fit modern mountain bike dimensions. But this rack can fit perfectly with the addition of the optional longer front carrier mounting arms and just a wee bit of work cutting the supplied cylindrical spacers to the length needed. The rack is good quality, fits perfectly with the changes detailed above, it easily clears my disk brakes, the provided machine screws are excellent quality, and it is rock solid on the bike. Just an FYI for comparison, I have installed the non-disk brake version of this rack on two other bikes in my family, not modern mountain bikes, and those racks fit their bikes perfectly with no modifications or extra work required.

When my bike became ancient history, I went and purchased a new 2020 Trek 5 xs (extra small) for women. I have short legs and I am only 5' tall. The rack seems to be built well, and so far no problems with it. It lost one star because the bars to the frame under the seat were not long enough, plus with arthritis in my hands it was slow going, plus I am older. Now 68 years old, yet otherwise it was easy to install.Reading the other reviews, I went to the bike shop and purchased some extenders, measured them, and cut them to the length needed. I used a horse rasp (course file) to smooth the cut ends and get rid of the snags. I also went to Lowes and purchases all new bolts for it which I have in the pictures. I also used lock-nut washers instead of theirs for a more secure fit. I wanted to use as many of the original parts, (except the bolts and washers) as I could.I rode the bike for about 10 miles and everything was great on it and worked fine. I did not use the panniers by the same company, Ibera, because my bike is an xs and I did not want the panniers too low. The panniers I used are Vincita and they fit just right on the rack. As the pictures show, the rack has plenty of clearance from the tire and my seat, and it is level. I purchased the rack for disk brakes as that is what I have.Later I will remove the 2 pieces of extenders and spray paint them black to match the rest of the frame. Presently I am extremely satisfied with this rack. I ride in the lower hills for pleasure and do not foresee any problems.Update: I forgot to thank another person who posted, @Bailesie who originally posted about which bolts to get. Thank you very much @Bailesie.

UPDATE:I received the lights I ordered, the Blitzu Gator 390 set which includes the rear light as well. It was an amazing value, and the lights work well. But more importantly, the rear light fits on the back of this rack. I mistakenly thought the rear light in that set would use a standard clip rather than a quick-release mount, but it uses the same mount as the front light. However, as it turns out, wrapping the rubber band around the rear tab fits like a glove. It's not as nice as a properly bolted bracket of some kind, because I'm afraid the rubber may wear out eventually, but for now, it fits perfectly. So if you need lights for your bike and want to run this rack, I highly recommend the Blitzu Gator 390. See the attached pictures for the fit.ORIGINAL:What an absolute steal for a quality rack. While there are some cheaper, more generic alternatives, they all seem to have less support for heavier loads, and of course with this, you get the PakRak system if that's something you're interested in. This rack, along with the PakRak trunk bag I bought, does have some flaws. I gave the trunk bag 4/5 because of some of those flaws. However, I don't think I will dock a point for the rack, because quite frankly, it's hard to find a generic touring-quality rear rack of comparable quality at a lower price. So even if you never use the PakRak system, this is a good value. Getting PakRak is just icing on the cake, and the bags are where you incur most of the additional expense.One thing I was worried about was size. I have a 2017 Giant Escape 1, frame size small, and I had read and heard on multiple occasions that the arms on rear racks need to reach further for smaller frames because the seat stay eyelets are relatively lower. On my bike, the length of the arms is perfect. They're pretty much fully extended, but with enough extra to know there's no risk of them slipping out. The bag is also not pressed up against or under the saddle as I had feared, nor is the rack leaning forward or backward. In summary, I had no sizing issues whatsoever on my small frame. That's not to say other bikes won't have sizing issues, but if your bike geometry is similar to the Giant Escape 1, a pretty typical city bike, then you shouldn't have a problem.I wish this rack had a solid section similar to the Topeak MTX system, because my bike does not have built-in mud guards. The Topeak racks effectively work like a rear mud guard, which is a nice added bonus, but the Ibera PakRak racks do not. Instead, the bottom of the bag is a hard shell, so while the bag will keep your back clean and dry, it will also carry dirt indoors. It's not the end of the world, and the PakRak system is a much better value at current prices, but it's something to keep in mind.One thing I find a bit awkward is the rear tab where one would mount a reflector or light. It seems like there are some reflectors which would mount without additional hardware, and Ibera does sell some lights which fit natively onto the rack. But the choices are limited, and I wanted a specific style of rear light which uses a quick-release mount as opposed to a standard clip. I also wanted the rear light to be USB rechargeable. Ibera sells no such lights, so it seems I may need to fashion something myself out of parts from the hardware store. I'm not sure why rack marketers sell this as a big feature, because there doesn't seem to be any standard across the various racks I was considering. Honestly, the most standard thing they could have done was add a small section of post in the back so that lights meant to mount on a seat post (which appears to be the majority) could fit without a hitch. Unfortunately, there don't seem to be any racks with such a post included.Overall, this rack is a fantastic value for the money, and its minor flaws have more to do with the design of the PakRak system and the rear tab than the build quality. This is easily one of the best rear racks currently on the market, with a good load capacity, and space for simultaneously mounting side panniers and a top trunk bag.
