Our take on the ultimate all-round gravel bike. Go anywhere, bring everything and then keep on going.
One chainring, endless possibilities. The Topstone 3 GRX - 1X delivers simplicity without sacrificing performance. A Shimano GRX610/820 blended group keeps shifting precise and reliable, while KingPin suspension takes the sting out of rough terrain. WTB tires keep you connected to the trail, making every ride a good one—whether it’s a quick lap or a full-day escapade.
FEATURES:
- Smiles for Miles: Kingpin is our lightweight, go-for-longer rear suspension. Maintenance-free and complexity-free, it gives the Topstone frame legit rear-wheel travel without compromising stiffness for the sprint. Kingpin provides a smoother ride, more traction to push harder, and more give to take on the rough stuff. You’ll hardly know it’s there, but you’ll be very glad you’ve got it.
- Bring It All: Our all-new StashPort storage system in the downtube is designed to be concealed yet convenient. Paired with the special StashBag, you can bring your essentials along for the ride and know that they’ll be kept safe, whatever you get up to out there. Meanwhile, multiple mounting points on the frame, mean more gear and more adventures.
- Tuned Ride: A dialed-in ride, just for you. AKA: Proportional Response Construction. Everything from the carbon layup to the geometry on Topstone is individually tuned by frame size. So that the bike – including KingPin suspension – works in harmony to give you the best ride for you and your dimensions.

Great suit, but size up
Size: Large, Color: Black, Size: Large, Color: Black
This set comes with a jacket, pants, extra buttons, and a bow tie with an easy clip to remove it. The suit itself is really nice and I love the pattern, however, I thought I purchased a XXL, but seemed to have ordered a L instead. Not quite sure how that happened, but suffice to say, he could not fit the suit. He is normally an L in pants, so based on the fit, we would have needed to size up anyways. He couldn't fit his leg in the pants or his arm in the jacket. I automatically size up on items like this because you can take clothes in, but can't take them out if there is not enough cloth. The suit pants are not lined, but you can see that they did leave room for the legs to be let out. Perhaps if we have the pants let out, he would be able to wear the pants. The jacket is fully lined and it comes with two inside pockets, one can be buttoned. I cannot tell if the jacket has room for alterations, but I might have him fitted for it just to see. It comes with a slit on the back of the jacket, so it has that going for it from a quality standpoint. It does come folded so you have iron or dry clean it before wearing. The quality is good for the most part. There are some threads coming out of the bow tie, but that's all I seen that is less the good. I'm giving it four star based solo on it's look and feel. Of course, I can't comment on the fit. For around $80, I definitely think it's worth checking out for a school semi-formal or fancy dinner out. It might be a little lightweight for a higher end event. Did I say I love the pattern?

Stylish look and great value for special occasions
Size: X-Large, Color: Blue, Size: X-Large, Color: Blue
This suit looks really good in person. The pattern adds a nice touch that makes it stand out without looking too flashy. It is a great option for events like weddings, parties, or prom where you want something a bit different from a basic suit.
The fit is slim and modern, giving a clean and sharp look when worn. It feels comfortable enough for a few hours, and the overall shape looks more tailored than expected for the price. The jacket sits well, and the pants match nicely to complete the set.
The material is lightweight and decent for occasional use. It does not feel like a premium suit, but it looks good and photographs well, which is what matters for events. The bow tie included is a nice extra and helps complete the outfit without needing to buy more pieces.
It may need a quick steam or ironing out of the package to look its best. Also, checking the size chart is important to get the right fit.
For the price, this is a very good value. You get a full outfit that looks stylish and put together without spending too much. Great option if you need something affordable for special occasions.

Stylish Statement Suit for the Price
Size: Medium, Color: Gold - Embroidery, Size: Medium, Color: Gold - Embroidery
I really like the black with gold embroidery on this suit - it really will make you stand out. The gold does have a slight green tint to it in certain lighting, but overall I like the unique design and think it looks great.
The pants have some flexibility, which made them more comfortable than I expected. I got a Medium - and im usually a 32W. I could see it fitting a 30W or34W too. It arrived in great shape and was not wrinkled at all, though i'm likely going to have to hem the pants 1-2 inches. The pants are neutral and could be worn with other black jackets.
I am usually a size 42 bust in jackets, and while the size chart says medium is a 44 bust, i think this fits me like a glove.
It also came with a bow tie, which is a nice added bonus. Overall, I think this is a great deal for the price and a solid choice for anyone looking for a versatile standout suit for a formal event or a costume party.

Way better than expected - Not a "costume" at all!
Size: X-Large, Color: Christmas Green
I’m going to be honest: I was fully prepared to open this package and find a cheap, shiny, flammable-looking costume that belonged in a discount Halloween store. Buying a tuxedo on Amazon feels like a total gamble, and I was definitely a skeptic.
I couldn’t have been more wrong. This suit is actually fantastic.
First off, the fabric. It doesn’t have that "plastic" feel I was dreading; it actually feels elegant and has a nice weight to it. The floral pattern is sharp and the colors are vibrant without being "too much." It looks way more expensive than the price tag suggests.
The fit was the biggest surprise. I’m always wary of "slim fit" labels, but this hit the mark perfectly. It’s tailored in the right places without feeling like I’m about to burst a seam if I sit down.
I originally bought this thinking it might work for a one-off event, but now I’m genuinely excited to break it out for an upcoming casino night and a wedding later this year. If you’re on the fence because you’re worried about Amazon quality, just go for it. This is a legitimate suit that’ll definitely get you some compliments. 10/10 would buy again.

Showstopper! Incredible Fit and Stunning Floral Design!
Size: Medium, Color: Black
I bought this Mgnaie floral tuxedo for a special event, and I was absolutely blown away by the quality and the fit! Getting a slim-fit suit online can be a gamble, but this two-piece set fit perfectly right out of the package. The blazer hugs the shoulders beautifully, and the pants have a modern, sleek profile without being too restrictive or tight.
The floral pattern is exactly what I wanted—bold and eye-catching, yet elegant enough for a formal setting like a wedding, prom, or gala. I received compliments all night long! The fabric feels premium, breathable, and comfortable enough to wear and dance in for hours without losing its shape.
For the price, you are getting a high-end look that rivals much more expensive designer tuxedos. If you want to stand out from the crowd in the best way possible, I highly recommend this suit. It is an absolute must-have for any formal wardrobe!
