Axiom Fatliner Bike Rack

This is a FAT Bike rear wheel bike rack. Even the bike shop was impressed at the quality. However, there are extremely few people who will attach a FAT bike rack to a mountain bike. There are other products which are only available in the USA and cost two hundred dollars MORE to get to Canada. And will take six weeks at least. This product was my substitute to this nonsense. The bike shop however, lacked the training required to secure this rack to a mountain bike. I know, because I spent an hour on the trails having to reinstall it correctly. To be fair, this is the type of training that is specialized. I chose this rack originally for a FAT bike, but was advised by professional bikepacking cyclists, to purchase a mountain bike for my localized terrain in British Columbia, Canada. After correcting the installation on the Myra Canyon Kettle Valley Trail, it holds an enormous amount of weight. It could use thicker steel plates at the rear wheel. However, I tested this rack in a “Shake” test. This is where we straddle on at least 50 pounds and physically and violently shake the bike sideways and banging it up and down for at least two minutes. To see if there is any flexing in the metal used and if anything will fall off the rack? Success! It passed. I ride some really rough washouts and ponds (yes, large shallow ponds past the pedals) and potholes that are deep and rough. At no time (over one hundred miles) did anything ever move or come lose. So if you are looking for a bike rack that is super strong and you worry about losing stuff falling off your bike rack deep in the forest, this is well worth the $200+ I paid for it.

I’ve used both the streamliner and the fatliner. The fatliner is about 1.5in too wide, and the streamliner is about 1.5in too narrow. But they’re both really good. Well made, though the coating will wear off. The thing I like most is the offset to give you more room for your pedal stroke. You may want to get some loctire (222 I believe) as riding tends to slowly loosen bolts.

excellent merci encore .

Fits on my new Motobecane Boris the Brut 21 inch frame. Tires are 26 x 4.7 inch wide. I had to shorten the extension arms with a hacksaw, but that was no big deal. I needed to stretch the rack open a bit wider to fit on the outside of my 197mm frame at the rear axle, which made it a little tricky to hold in place while I installed it. I ended up mounting it to the attachment points for the rear derailer hanger and disc brake. I see now that the product description says “Fits 170-190mm dropout spacing” -which explains why I needed to stretch it. I also needed to file down the rear derailer hanger slightly (about 0.5mm) where it was contacting the mounting bracket for the rack, in order to allow the rack to rotate forward into a level position. I was able to file down the rear derailer hanger without removing it from the frame, but it might have been easier to take it off to file it because it was delicate work trying to file it without accidentally filing the frame. You could also file a bit off the rack mounting hardware, but I didn’t want to weaken the integrity of the rack. Once installed it seems solid and I like the way it looks. Not many options out there for fat bike racks. I think this is the best looking one and one of the least expensive. Good product.

It also comes with an additional bar for set post attachment. I did not use this, but I included a pic of it next to my seat post so you can see what it looks like. I guess this piece is for quick release seat post attachment, which my bike does not have and I never intended to use this installation method.

I wanted a rack to fit a mid-fat bike with a tire size (in my case 27.5×3″ tires) with a 148mm boost rear hub (which is probably ~175mm wide for the rack mounts). This rack fit absolutely perfectly onto my Jones Plus SWB bicycle. I made one easy mod, which is not necessary: I drilled wider holes into the top of the rack for the seat-stay mounts to be wider. Otherwise this rack is perfectly sized and everything lined up exact. Nothing needed to be bent or pushed to fit. I have loaded up the rack with a basket and some groceries and its very stable. No swaying, movement or noises. The rack feels like an original part of the bike.

*Side note – the pics include a Wald basket attached with 2 Nite-Ize 18″ twist ties. These are not included with the rack. I also paid for this rack and was not compensated for this review.

I bought this as it was one of the only racks that people said may fit my new fat bike. My bike has 27.5 inch wheels, so the rods don’t reach to attach to the frame like I had hoped, but I made it work with a replacement seat tube collar that has mounting points on it. I really don’t like the pieces that attach down by the axles, but they probably won’t fail before a bolt would break. I don’t plan on reaching the weight limit anyway, so I think it’s going to work out fine. Seems to be well made. It was half the price of what I was going purchase, so I’m giving it a try. So far, I’m liking it.
