to upgrade or not to upgrade that is my question. HELP ME!Stormin' Norman

Hi, I'm new to the road review and could use some advice. I currently ride a "Cadex 2 Carbon Fiber Racing" road bike with RX100 components, aluminum fork and Wolber rims mated to Shimano LX hubs. I bought it used about 4-5 years ago, but have only recently begun using it much since putting away my mountain bike. It's in perfect condition.

My question is: how good is this frame? I know that it's carbon-tubed, bonded to lugs of what I guess are either aluminum or thermoplastic. I can't find info or reviews on this bike anywhere and I wonder if it's worth upgrading or if I should simply purchase a new bike.

I know that Giant, and many other companies, use the same frame on bikes in a wide range of price points and I'm hoping maybe this frame is worth hanging on to.

The RX100 components are in need of an upgrade: I only have seven cogs in back which I find limiting and I would like to replace my downtube shifters with integrated brake shifters. I'd also like to shed some weight in the process. Is this frame worth what amounts to a new drivetrain and rear wheel (or re-build with new hub)?

Any adivce would be greatly appreciated

he bike you have is 7-speed. The 8, and later 9, speed drive trains used a slightly wider axle. If you had a steel bike, you could have a frame builder stretch the triangle for you. Its not possible with a carbon or aluminium bike. I did do it with an old Cannondale I had with some 8-speed Ultegra parts I had laying around. The rear wheel didn't center and shifting wasn't great. Never the less, I rode it for a year or so until the drop out broke, ruining the frame. That was one bike I was glad to see go.

Even if you could upgrade, its not worth the money. The Cadex frames are carbon with aluminium lugs. I don't know how the bike rides, but I doubt it was ever a high end bike to begin with (not saying that its a POS though). You'd probably be better off saving your money towards a better new bike. To completely retrofit your Cadex would cost $600-$700 or so (you'll need a new rear wheel too). There are nice bikes out there in the $1400 price range (e.g., Giant, Fuji). Unless you truly have a high end frame, re-tro fitting isn't worth it. I did it with my Kestrel 200 Sci two years ago because the Ultegra 8-speed group was shot and I felt the frame had lots of life in it.

You bought a CF frame (bike) used 4-5 years ago... I wouldn't upgrade for no other reason than you don't know what the frame life is. The frame failure issues surrounding CF have improved dramatically in the last 1/2 decade, but you're sitting on one built before that. Save the dough and get a bike where you'll know everything about your frame and get the components you want.

If you look at new bikes in the $1000 to $1500 range you are going to find a better bike than you could ever upgrade your existing bike. Check out KHS and Jamis-I think these brands have some outstanding values. I think you are going to have serious problems upgrading your present 7 speed to 8 or 9 speed compatability-wise for the previous posted reasons.
