And speaking of bb's I went with a 68x113 bb and the chain was way out of alignment, so thanks to my biking buddy, we did two things, and now it is in perfect alignment.First,I went with the narrowest bb I could find a 103mm and the thing that really did it, was flipping the chainring to the other side of the crank,(thanks again Jimmy Z) A simple fix, but I never would have known to do that."
"It is possible to put it together on your own at home, but I had my local bike shop cut my fork and when they did, I had them install the headset as well. I highly suggest taking the frame to your local bike shop so that the headset and fork get installed properly. I rode a day ride with the included seat post and it honestly did fine, only turning out of place a few times. I put on my Bontrager RaceLite carbon fiber seat post (also size 27.2mm) on the frame and it fit better, but still slides around. The holes on the fork and rear of frame are perfect and fit the Shimano Dura Ace 7800 break set I have. List of components I am currently running on this bicycle: FSA 110mm stem. Salsa Cowbell 3 handlebars (with Cinelli handlebar tape). VELO leather seat. Bontrager RaceLite carbon fiber seatpost (not pictured). Zipp 404 clincher carbon front rim (with Dura Ace hub and Continental tire). Weinmann DP18 rear rim (with Shimano fixed cog and ThickSlick tire). Origin 8 3-piece crankset. Shimano UN55 bottom bracket. Stolen bike co Thermalite pedals. Origin 8 foot straps. KMC gold chain. Four stars only because the seat post doesn't fit perfectly."
"Overall a good purchase seat post locks fine but it will rock forward and back a little."
"Awesome frame."
"Great frame no problems at all very stiff and well made would recommend for others."
"Excellent frame at a great price."
"Installing the bottom bracket and crankset was easy with all the tools in hand."

"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."

"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."

"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."
