Since the normal rider seldom exceeds 250 watts top output, does aero design actually make any significant gain over the older steel tube bikes with a tube diameter so much smaller? I had a serious concussion about 14 years ago which destroyed a good deal of my memory so I had to start from scratch again learning about bikes again and went through everything from my old Basso Loto to Trek top of the line bikes with those crappy BB90’s. So here is something that the Great Hambini should address. But I am passed often enough by younger riders that think that they gain an advantage by aero designs. I have discovered that I cannot tell the difference in climbing between a 20 lb bike and a 16 lb bike.

If you are familiar with bike construction then this should be no problem.OK, here you and I are, not pro riders. The instructions are quite sparse so if you are a newbie to bike building then you may want to get some external help for assembly. The bike frame arrived well packed with no cosmetic damage. Transit times from China are around 3 to 4 weeks.

The drillings for the bottle holder rivnuts showed now fraying which indicates well compressed layers and care taken to drill the holes. Internally, the frame was extremely clean, there were no displacement voids or indications of poor carbon layup. ICAN A22 Bike Frame Front Fork Frame Internals The threaded inserts had a little overspray of paint on them which was easily removed. Left and right fork leg alignment was good. The fork is set up for hydraulic applications and features a drilled hole to accept a hydraulic line which is routed internally to the front caliper. The steerer tube has plenty of excess and will require cutting for all applications. Both bearing seats are tapered do fit into the frame. The bottom bearing is approximately 1.5″ whilst the top is 1.1/4″. It has a tapered headset arrangement, the bearings for this are included. The rider is unlikely to get a Specialized steerer tube type failure on this bike. Someone has thought about the cable routing and the bend radii are as large as they could reasonably obtain within the size constraints. The steering tube spacers are anodized and the fitment is very good. There are some other features on this frame that would be worthy of a premium unit. ICAN do offer a number of different sizes so it is wise to check before ordering. This seatpost may not be suitable for seats with carbon rails.įrom a practical perspective, the inclusion of an integrated stem and handlebar combination means the angles and the lengths are fixed unless you change those components. This is linked to a micro adjustment seat post which allows for a large degree of tilt adjustment. The seatpost has a semi aerodynamic profile, the tail section being cut off for structural reasons. The seatpost features a knurled wedge, this is an intricate part and the addition of knurling to reduce the requirement of carbon grip paste is very welcome.
There was little angular deviation or distortion.
The geometry accuracy across the frame between datum and accessory points was very good. Some commenters on the YouTube video review suggested this may be a “Hambini Special” and would not be available to everyone, ICAN responded this was standard manufacturing method across the board. Given the price of the frame and accessories it is a welcome addition. That is quite unusual as that is a costly and time consuming process. ICAN supplied this frame with a machined bottom bracket. It is shares some similarities to the Canyon Aeroad. The frame is an “Aero” style disc equipped unit. For what seems like a small sum, you get a lot of bike for your money, the frame, handlebars, thru axles, seat post, headset, bearings, top cap are all included. The bike frame that was sent for review was a bare red ICAN A22, the retail value of this is circa $800USD. These products have predominantly been wheels and of late bike frames. They originally started off as an OEM and have recently started to sell items under their own name. ICAN is a company based in Shenzhen, China that has been building carbon fibre sporting goods for many years.
