What They Say...

One of the first gravel-specific bikes released, the Curve GXR model has been around since well before gravel became cool. Now, with wider tyre clearance, improved mounting options and UDH compatibility, the latest version of our Swiss Army Knife of bikes is more versatile than ever.

We have been ahead of the Curve when it comes to gravel, and the GXR has years of adventure cycling experience woven into its DNA. The Curve titanium GXR has been tested heavily on gravel adventures worldwide. Across South America, New Zealand, Switzerland, Swaziland, and more, the Curve squad has traversed the globe on this magnificent bicycle.

Originally a playful jab at the bike industry's bike naming terminologies, the name “Kevin” soon caught on, and we couldn’t resist making it official. Kevin, the reliable Aussie all-rounder, is here to stay as a permanent nickname for our beloved GXR.

The GXR has been designed with gravel cycling versatility in mind. While the GXR geometry is optimised for 700c x 44mm tyres, you can go as wide as 50 mm tyres on 700c wheels. In 700c mode with narrower tyre options, Kevin is ready for fast gravel missions, but you’ll be surprised how capable Kevin is on chunkier terrain with a 50 mm tyre. With 650b (27.5”) wheels you can move into gravel-plus territory with 2.2” tyres which offer plenty of comfort for the most rugged gravel adventures. Curve has the above wheel options in carbon and aluminium available and ready for complete Kevin builds.

Great product
Size: Medium, Color: Black,navy,melange,london Blue,burgandy
I adore these! They're so comfy. When they first arrived they felt a little snug in the waist and leg holes, but I gently stretched them out before putting on and have had no problems since, even after washing/drying, i just put on delicates cycles. The slight snugness normally wouldn't bother me at all and most of my other undies are tighter, but I had surgery for endometriosis back several months ago so I need/needed something comfortable. I'm used to wearing hip huggers or bikini briefs. I was concerned that boyshorts would ride up or that the legs would roll-which they do roll up slightly, but it's easy enough to adjust when putting on clothing and then I have no issues!-Once I tried these, they've become my favorite underwear. They're very soft and "seamless" and I like the fact they have no elastic. I have pain down my inner thighs that makes seams or elastic leg holes uncomfortable, but these undies are long enough and soft enough to provide coverage/protection in that area when wearing pants or leggings with inner seams, and makes it so much better to deal with. I just ordered another package and I'm excited to have more pairs to replace my old undies with! Really happy with this purchase.

A Bit Too Smooth
Speaking as a petite person, these following boyshort underwear passed so many comfort levels down from the fit, stretch, fabric feel, and describe shape of the material. When it comes to undergarments and living in a hot desert, breathable clothing is a necessity. It maybe "just underwear", but they are very complementing on the body and invisible in your movement. The crutch however, while the soft fabric maybe great with skin-contact - results with little grabbable or stickable surface for pads or panty liners that I own. Not having tried alternate pad or liner brands, I can't give a thorough idea of "Does it stick?" when it comes to this underwear. It's not to say it is completely unstickable, it'll will stick, but you really need to press in place. Major movement will crunch the pad/liner and you'll have to replace later in your day because you will feel it amiss.

Incredibly comfy and sexy but watch for health variables
Size: Large, Color: 2 Black,2 Blue,light Coffee
I love these so much. Incredibly comfy and no more awkward panty lines (with no awful thong string needed). I would have absolutely loved a grayscale-colored pack (black, gray, ivory). The gray ones are fantastic and subtle if the top band sticks out a bit with jeans (I thought the blue ones would blend better, but they stand out in a weird way? Maybe a darker denim color would be less noticeable.) These are SO comfortable I actually enjoy getting dressed in the morning more, lol. My husband also really likes how these look. I feel way more everyday-sexy than regular cotton briefs or bikini-style underwear or the like. *A big thing to be aware of is that these do not breathe the same way as cotton, so you need to make sure your netherparts get adequate opportunity to air out so you don’t get a yeast infection. Your vaginal ecosystem will get out of balance if it’s too hot and/or compressed on a regular basis (like with yoga pants or etc.), so make sure to trade off with other more breathable underwear and give your body time to breathe and cool down. If this same company also made 100% cotton boyshorts in a multipack, that would be all I’d ever need!

I have bought 2 packs of these now, I love them! I wear them mostly to bed or under sweatpants, they're super comfy and good coverage. I don't really care about how these look, I just like not feeling like my underwear is too small for me with my belly or my butt hanging out! I followed the size chart and 3XL sounded way too big but these fit great, tight enough to stay up but don't hurt or leave marks on my thighs/stomach. (for reference: 5'5, 200lbs, waist 32, hips 46)

Love everything except for the seams
Size: Medium, Color: 2 Black,2 Blue,light Coffee
This material of the "2black, 2blue,1 light coffee" color pack is wonderfully silky, soft, and stretchy. The colors are great and they look good on me. The only issue I have is with the seams. I'm very glad there are no seams at the hips, and I know because of that, the seams have to go somewhere. Isn't there a better place to put them than across the most sensitive female area and under my rear end so I sit on hard seams all day? I use these for my sleeping undies, and they are great for that because they're soft and pleasantly snug and so comfy to sleep in. I couldn't wear these during the day and sit on these seams for even 15 minutes. I'll admit I'm sensitive to seams but these leave a significant hard lump (especially contrasted with the wonderful material) and it's such a bummer to have them right under the bum! And across the female parts! The first women's underwear manufacturer that figures out a place to put the seams that aren't digging into hips, scratching sensitive female parts, or situated directly under my rear end while sitting will get ALL MY BUSINESS AND PRAISE. Edit: I purchased a second pack in different colors called "Black,navy,melange,london Blue,burgandy". The material of this second order is not as soft and silky as the first. It's wearable, but has a scratchy roughness to it. The material of the first pack I bought (2black, 2blue,1 light coffee) is much much better.
