Reviews

Very nice bike. I swear

"Very nice bike. I swear it rides better than my carbon Felt. Low quality bar tape but Ultegra components are top shelf and work perfect out of the box with no adjustments."

— PAUL S. (5/5)

Bike was impeccably packaged &

"Bike was impeccably packaged & delivered w/o a single blemish on the box. Noticed cobwebs in the spokes, which was no matter yet I did make it a point to lube fittings, apply some Wolf Tooth bar tape, install toe cages, a modest CatEye cyclometer, some 30mm GreenGuard tread & a ShockStop stem ~ All told, am one happy clam & I believe my son will enjoy it for years to come ~"

— John R. (5/5)

The bike is amazing. Very

"The bike is amazing. Very lightweight and fantastic groupset. The ONLY negative is that Vaast cheaped out on the bar tape. Less than 200 miles and it’s shredded. I’m 5’11” and the 56 frame is perfect for me."

— Matthew A. (5/5)

The bike is a great

"The bike is a great value. Looks great and rides really well. The 54cm frame fits me great at 5'9". The fork steerer tube is long and has quite a few spacers to dial in the fit. The frame is fast and comfortable. Accelerates well but isn't too harsh. Nice parts spec with 11 Speed Ultegra. The finish of the bike looks really good. A couple of downsides, as others have noted the handlebar tape is a joke. Literally coming off on the first ride. I wish they wouldn't have wrapped it and saved me the trouble of undoing it. Also, the derailleurs weren't dialed in. Not a big deal if you are comfortable with doing your own adjustments. The seatpost takes a second to figure out but not sure why so many people have problems with it. Same with the seat clamp, it is a different design than what is common but it works if you pay attention setting it up. Overall, I am really pleased with the bike and the value. I would give it 5 stars but having to immediately change out the bar tape and fiddle with the derailleurs drops it one star."

— Kyle F. (4/5)

great buy

"It was easy to put together. The tools were pretty good too. The instructions were a bit vague, but I have a cyclist friend that really helped me. I really love it. Shifters are responsive and the breaks stop quick. Thats helpful as sometimes stopping quick is definitely needed."

— Sherry (5/5)

No Regrets!

"I took a chance having never owned or ridden magnesium before. Wow! So happy I got one of these. Fantastic ride quality. Plenty of snap. Long-ride comfort. Great fit. Such a well-equipped bike, too. Probably going to be my forever bike."

— Kevin P. (5/5)

Amazing deal!

"Can't believe you can get a bike this well equipped at this price. I have the Vaast R1 Ultegra. Magnesium is amazing. Lightweight. Smooth ride quality. Rides more like carbon than alloy. Love this bike and it is a steal at this price. I bought this bike having no prior experience with a magnesium frame and I have no regrets whatsoever. I really like the black cherry color. Praxis Carbon cranks a big plus."

— Kevin P. (5/5)

Seatpost clamp is dangerous

"Like others have said the handlebar tape is terrible and reflects poorly on the brand. I wish I would have called Cambria like others did before spending $35 on quality tape. The bigger issue is the seatpost clamp. The bolt comes loose. Twice now at almost 1,000 miles of riding, the seatpost has collapsed into the frame after hitting a small bump and is constantly loosening with my seat slowly lowering. I am 6'2" and 270lbs, but also 55 years old and only riding on pavement. I've reached out to Vaast to see what I can do. Otherwise the bike was a tremendous value during the black friday sale."

— Ken K. (4/5)

Best Bike

"It is vey comfortable and fast"

— David (5/5)

AS I started to shop

"AS I started to shop for a Road Bike to replace my ten year old Ridley Orion, mechanical Ultegra, I read the reviews of the Magnesium Ally VAAST R/1 Road Bike. After reading positive reviews, I purchased the VAAST R/1 Ultegra (mechanical) on May 6, 2025. After 4 rides total of 109 miles, I can say that I like the bike and highly recommend it. The VAAST Magnesium Alloy road bike is one pound lighter than my Ridley carbon fibre. It rides and handles great. Having mechanical Ultegra derailleurs on my Ridley, I could not settle for anything lower on the VAAST. The VAAST shifts precisely and crisply. Overall the ride is great, comfortable, smooth and forgiving on 30+mile rides with more to give in even longer rides. The CONS: 1) As sure as reviews on VAAST bikes, the handle bar tape tore and deteriorated only after the first 30 miles. Couldn't VAAST have installed more durable bar tape? 2) The semi-internal cabling is not pretty on the cockpit. Other carbon fibre road bikes of similar caliber with internal cabling systems are much better and neater looking. 3) still getting used to the wheel release system which is different from the flip lever style. To conclude, I have no regrets purchasing the VAAST R/1. I will enjoy riding it and putting more miles. Good riding all!!!"

Q&A

what bike size is recommended if I am 5' 7" tall ? any other measurements needed? I prefer riding upright.
I feel that if you want a more upright position, the 52cm would bring your hands in closer to your body to give you that feel. The medium might stretch you out a bit and make your position drop downard a bit. But that’s just my opinion...
How long is this sale? What size is recommended for 6'? Note recommended is 180 cm but ordering says 54cm?
If you're 6' tall, depending on your leg length, I would look at getting the 58cm. I'm 5'11" but have shorter legs and longer torso so I bought the 56cm and if fits me perfectly.
Hi, for a 5'6'' and 28.5'' inseam, the manufacturer's online sizing tool suggest XS. But the geometry chart recommend a size S. What would you recommend?
I recommend you buy another bike. This bike has a poor design for the seat post. It slips badly and when not slipping it creaks. I can not return the bike to Cambria because I rode it some and Vaast refuses to answer any of my messages. Seems I have wasted my money.
Are assembly instructions included? how hard is it to assemble this bike? I have never assembled a bike before.
This bike comes pretty well packaged and partially assembled. You will need to install the handlebars and wheels. Plus the stem and seat post.. You don't need to do any of the hard stuff like install brakes or derailleurs. The seatpost is tricky on this bike. Changing seats is the only thing I don't like about this bike. If I could id buy another one of these, it's a sweet ride for the price. And yes, instructions are included and even comes with a miniature tool kit for putting it together
What size would the manufacturer recommend for a 5'8 rider, 145 pounds and 29 inch inseam? Thanks.
I am 5'10 and ride the extra large very well...For the above question, I would opt for the large...
