"I've reviewed this before."
"Super light, we'll constructed frame and fork combo."
"Very nice frame, carefully packed."
"I talked to my local bike shop and looked online and decided on this frame for a few reasons. Thirdly, I wanted some piece of mind when ordering and Amazon provided this compared to some other online vendors. Through email exchanges, Bella with ICAN said to let her know my preference of bottom bracket and she would make the switch on her end. My biggest worry was installing the bottom bracket and making sure the housing was square and aligned to avoid creaking. All of the threaded areas (brake calipers, bottle cages, cable housings) were spot on and I didn't have any strip out on me. The build consisted of aluminum stem and aluminum 44cm bars, ICAN carbon seat post, Ultegra derailleurs front and rear, FSA SL-K light carbon crank, TRP HR/RD calipers, Stan's no-tubes wheelset, Clement X'Plor USH 700x35 tires, Look KEO pedals, and specialized Avatar saddle."
"We took the innovative reverse curve fork and our incredibly stiff and smooth frame and added a Front 100*15mm Thru Axle and a Rear 142*12mm Thru Axle to make it even better for 2016. We have taken the Aero bike and crossed it with a comfort Gravel bike so that you can not only be the fastest in the group but also feel the freshest at the end of the ride. It has a reverse curve front fork which is stiffer in a sprint and more compliant in the bumps than a standard forward curve or strait fork. I find that the reverse curve forks do not flex as much due to the axle not being as far forward from the front of the bend so we maximize your sprinting power. Other Features include: Aero shaped head tube for maximum efficiency at the front most part of the bike. Internal cables to protect them from impacts and also make carrying the bicycle more comfortable. Flex ports for easy adaptation from Mechanical to Electronic drive train. Di2 ports integrated into the frame. A round seat tube which allows for a clamp front derailleur which can accommodate very small or very large chain rings without issues, unlike some bikes with short braze ons."

If so the Cycle Force Cro-mo Cyclocross Frame 46cm might be for you. Head Tube Length: 115mm.

"As I unwrapped the frame I tried to get my son to look away because once the poor quality of the welds alone became clear, I feared his face would melt (a la Nazis in Raiders of the Lost Arc) due to being exposed to such horrendous work! I ended up getting the Performance entry level frame and fork and couldn't be happier... built up fine and is made to last."
"The major pain I had was that when the fabricator drilled into the bottom bracket to weld on the chainstays, they drilled right through the threads and left some major burrs."
"You get what you pay for and I got a cheap frame that equals its price."

"Habanero frames are just superb. I like it so much, I recently ordered another road frame, AND a mountain bike frame."

"The best thing I liked was that the manufacturer published all the pertinent specifications, including the weight."
"Really nice built.frame."
"Headset pressed in without issue, bottom bracket threads and facings were clean....really no complaints at all."
"The frame is excellent and it fits my day to day riding."
"Great frame, super low price."
"It's not as light as the latest and the greatest carbon frame but it's not nearly as expensive either. Also it would make no sense to hang heavy parts from a $800 donor bicycle on a carbon frame."
"I understand it was out of warranty, but a bike frame shouldn't break after a year."

"One suggestion to anyone using this frame, it is shipped with a bottom bracket, and the part is fine, but like all press in bottom brackets, it will get noisy over time."
"this frame is the same as the Fasteam i bought some months ago."
