"Perhaps it’d be better to just put it this way: were we in the market for a gravel bike like this, either Mikey nor I would hesitate to own one of these ourselves, and you shouldn’t, either."
"Perhaps it’d be better to just put it this way: were we in the market for a gravel bike like this, either Mikey nor I would hesitate to own one of these ourselves, and you shouldn’t, either."
"The Shafer is a versatile drop-bar machine that can handle just about anything. Use it as a fully rigged bikepacking vehicle, winter training bike, or lightweight race-ready gravel grinder."
"Typically we get a few gravel bike introductions sent to us in press release format here at Riding Gravel every month. Not very many make the page here because, honestly, they are not all that interesting. The Fezzari Shafer being an exception here."
"The Shafer handled tight, fast turns with confidence, and I had no problem rolling roots, rocks, and even a few scary drops."
"Mounting points galore will accommodate whatever racks or fenders you want to adorn it with. Go out, go long, and tell great tales with the Shafer."
"If you are looking for a bike that can confidently take you on an adventure where a little less under-biking will increase the fun factor, you cannot go wrong with the Shafer."
"The new Ari Shafer has been updated to offer better handling, more bikepacking-friendly features, and bigger tire clearance."
"Ari’s newest bikes look to be just as, if not more up to date with the latest trends as most major manufacturers."

Common Questions*
Do you offer financing?
Yes, at checkout there are several options available for financing.
Who is this bike for?
Shafer cyclists appreciate versatility in cycling, combining the love for both on-road efficiency and off-road adventure. This cyclist seeks the freedom to explore less-traveled paths, such as gravel roads, forest tracks, and light trails, without being limited by the capabilities of a traditional road bike.
How long will it take to arrive?
Estimated lead times are listed under each model's size in the bike builder. Times may vary a little based on current conditions, frame size, color, and availability.
Can the Shafer run a suspension fork?
Suspension gravel forks such as the Rockshox Rudy, 32AX, MRP Baxter or Suntour GVX, can be installed on the Shafer frame. You can add it during checkout on our website. If you choose to get one on your own later, we recommend running the longer fork offset option (as close to 50mm as possible).
What is the bottom bracket frame spec?
68mm English thread. Our philosophy is simple: if the bike is intended to be ridden in the dirt, it gets a threaded bottom bracket. Threaded bottom brackets are easier to service.
What are the dimensions of the front hub and fork axle?
The front hub is 100mm x 12mm. The axle dimensions are M12 x 120mm long x 14mm thread length x 1.50mm thread pitch.
Can the Shafer run an internal dropper post?
The Shafer can use an internal dropper post with a diameter of 27.2mm. The Shafer AL can not run a dropper.
What testing was done on the Shafer? Will it hold up to the demands of gravel and off road riding?
The Shafer was machined-tested to cross country mountain bike standards. We also added additional tests, like a rear impact test, to be sure the frame exceeds expectations in durability. Many different frames and frame sizes were also test ridden thousands of miles in all types of conditions. In ride testing the Shafer saw podium finishes in gravel races across the US, and thousands of miles of bikepacking across Iceland in rain, sand, and mud. You can ride confidently on the Shafer knowing it is backed by our Limited Lifetime Warranty.
What is the biggest tire size the Shafer can accommodate?
700x50c is the max recommended tire size. When equipped with a front derailleur, the max recommended tire size is 700x45.
What are the headset dimensions?
The Standardized Headset Identification System (SHIS) is IS56 / 28.6 | IS56 / 40(45°). This is used with the 1.5”/1.5” headtube. We have chosen to use the FSA SRS headsets for simple, clean cable management. FSA ACR is also compatible if the matching stem is also used.
What are the dimensions of the rear hub and rear axle?
The rear hub is 142mm x 12mm. The axle dimensions are M12 x 173mm long x 15mm thread length x 1.75mm thread pitch.
How are the cables routed?
All cables are routed through the headset. We have chosen to use the FSA SRS headsets for simple, clean cable management. This also helps keep the cables out of the way if you install a handlebar bag.
What is the frame weight of the Shafer?
The Shafer frame weighs 1160g including the derailleur hanger, seat post clamp, and full color paint. The Shafer is tested to XC mountain bike safety standards to be sure it can hold up to the toughest riding conditions.
How many water bottles can the Shafer hold?
Sizes Medium, Large, and XL can fit 3 bottles inside the front triangle, along with additional mounts on the top tube, underside of the down tube, and fork legs. Sizes XS and Small can hold two bottles in the front triangle along with an additional mount for tools or a bag requiring 64mm bolt spacing. Simply put, if there was an Olympic event for gear and hydration carrying options on a gravel frame, the Shafer would take the gold medal.
What about service?
You can work directly with us, one of our recommended shops, or work through your local shop.
What is the guarantee?
It comes with a 30 Day Love it or Return it Guarantee.
How will it arrive?
All Ari bikes go through our Custom Setup process, making sure the bike is fit and tuned specifically to you. They are test-ridden before delivery. If your bike is shipped to you, it’s still tuned and ready to ride and requires just a few minutes of assembly.
What is the warranty?
Each frame comes with a Lifetime Warranty. Ari branded frames come with a transferable warranty as well.
How does transferable warranty on Ari bikes work?
Ari branded frames come with a transferable frame warranty available to the second owner. The second owner can receive a one-year frame warranty from the date they purchase the bike from the original owner. Warranty only transfers once. All Ari bikes must have the transfer documented from the original owner to the new owner here in order to qualify for a transferable warranty.
