Built from a proprietary 7005 series aluminum. Specially heatred, this frame is strong, stiff, and ready to blast over the competition. Complete with full carbon rear triangle and Cyfac's own carbon fork.
Frame/Fork 1850 grams.
Strengths: A great, do anything, go anywhere bike.
Competent at everything
Beautifully crafted and finished
Weaknesses: None to speak of - toe overlap means you need to keep the front wheel reasonable straight at junctions and in standing traffic.
This review is based on 350 kms ridden in just over a week.
The Proxidium Carbone 56 cm frame arrived beautifully finished off in a deep, lustrous Mega colour scheme. Out of the box, the set up was perfect. The most noticeable aspect of the bike design is the large elliptical downtube with opposing axes at the bottom bracket and head tube (reminiscent of the old Columbus Max steel tubing) that presumably contributes to the brilliantly stiff frame and easy, immediate power transfer. The carbon back end has curved stays and really lovely replaceable dropouts. It certainly looks the part!
Handling is immaculate, coping easily with rough, rutted, unpredictable country tracks, and providing sufficient give to make the ride over these treacherous surfaces entirely predictable if not enjoyable. The ride really is very comfortable indeed, feeling plush on reasonable road surfaces and with very similar road feedback to my 'cyclosportif' light steel framed bike with a 2 cm longer wheelbase. Not only is the handling extremely predicable, it is lively enough to be immediately responsive to rider input. This inspires confidence and makes for relaxed, fast descents in all conditions.
A side-effect of the bike's great poise is a couple of cms of toe overlap likely to affect riders with shoe sizes larger than 44/45. Of course this isn't a big issue except when attempting a slow U turn or standing in traffic, and in practise for a bike intended for road riding and racing is a non issue, requiring minimal adaptation.
Strengths: Strong, durable, lightweight, superb workmanship, great value, great styling.
Weaknesses: The only weakness is I can't blame the bike anymore.
This frame is all class. I have been racing bikes for over 15 years and this is by far the nicest bike I have ever ridden. I have always loved the qualities of aluminum for a race bike. It is stiff, light, and relatively cheap. The addition of the carbon stays makes this frame unbeatable. Other details include an integrated headset, headtube cable stops, proprietary dimensional tubeset, ribbed carbon designed by some famous F1 racecar designer, sloping top tube geometry, monostay chainstay bridge for stiffness, and ultra secure seat collor with adjustment for carbon or alloy seatposts. The attention to detail and workmanship of the frameset is top notch. Welds are hand finished smooth. The paint job is impeccable, with no blemishes and a thick coat of clear. The rear wheel drops into the frame easily with a reassuring "ca-chunk" for quick wheel changes, and furthermore, indicating proper alignment of the dropouts. The cable stops are all set in exactly the right spot, and the front derailler cable has a super slick internal feed through the massive chainstay bridge. The bike handles great. It is comfortable and agile, but not too twitchy. It won't buck you because you are not paying attention. It is just predictable and responsible. I recently ran it in the Tour of Somerville in the pouring rain around greasy New Jersey streets at full speed with nary a slip. The bike is balanced, stiff where needed, compliant where needed, and seems very durable. I would highly recommend this frameset. Other framesets which would compare would cost $500 to $1000 more and they would be mass produced with no style.
