Yet another "which bike" post(14 posts)

Yet another "which bike" postiuratus
Sep 25, 2002 12:16 PM
Choices:
Viner Pro Team V5 from GVH. Frame weighs about 1300 grams, Altec alum. $1800 shipped with Centaur, Cinelli bar/stem, Open Pros, Conti GPs, Daytona Pro-Fit Plus pedals.
Cervelo Prodigy from Supergo. Columbus Thermacrom. Also $1800 shipped, with Ultegra, Cinelli bar, suspicious "alloy" stem, Ritchey wheels, Kenda tires, no pedals.
Other bikes from GVH. C-dale CAAD5 w/ Ultegra -- $1400. Raleigh R700 w/ Ultegra -- about 1050 (not all sizes).
All suggestions are welcome. I'm built like a climber, so I'd like something stiff enough to help me out. I'm 16 yrs old, so I don't want to spend a fortune on a frame that I'll outgrow. I also don't want to skimp, though. Right now I'm riding a $300 Motobecane Mirage with Sora/noname, weighs 27 lbs and flexes all over the place. Not great for climbing. Rode my first century on it Sunday, 16.5 mph average isn't too bad for the first time with a 27 pound bike, clips/straps. But I digress. Thanks for replies

The Prodigy comes with three things I'd ditch before riding.

#1 - Kenda tires - Suck! Worst road tires I've ever used.
#2 - Cervelo house brand brakes - same as #1 They're the worst dual pivot brakes I've ever encountered
#3 - XO Flite Gel saddle - same as #1 & #2 It is possibly the most uncomfortable saddle ever designed.

Add 60 dollars minimum for good tires and 60 for a set of 105 brakes and 50 for a real saddle.

You're now at $1970 with a generic stem, cheap bars and hard to adjust Cervelo seatpost.

just my 2 cents

...with a few new parts, and you can be riding the same frame which CSC-Tiscali will ride next year on the Pro Circuit. Plus, it is made in Canada, and I'll vouch for it. If you outgrow it soon, sell it to me! (As long as you buy it in 56cm frame).

It is light enough, and stiff enough. The Aluminum bikes you are considering might not feel so nice on a century.

Steel is Real.

Maybe find an LBS selling Cervelo, and they'd be willing to fix the parts where Supergo won't change anything(or FIT you).

Oh, PMC: The Selle Italia Tri-matic is the worst saddle. Terrible!!

Selle Italia Tri-matic - never tried that one luckily.

Other than my nit picks it's a great bike. Love the ride, the geometry fits me perfect (in a 58cm sorry) and I love the understated graphics. I stripped mine down to build up another bike but I'm in the process of rebuilding with full Dura Ace and some other goodies. The frame is well worth it if you dig good steel.

Of what you list, the Cannondale CAAD 5 is the best aluminum frame. The Cervelo is a nice steel frame, but it will not be as light as the Cannondale, not that that is everything. Don't forget to checkout the Giant TCR1 if you are looking at aluminum bikes. In aluminum, in general, look for a bike made out of a 6000 series material, not 7000 series like the Viner or the Raleigh. All aluminums are not created equal.

I never really understood the difference between tubes. The Viner frame is plenty light at under 3 pounds; what is sacrificed? Thanks

Altec and other 7000 series tubes are heat treated as tubes and can be welded and then simply "aged" following the fabrication. 6000 series aluminums like Cannondale, Giant, some Trek and others require heat-treating following fabrication. Solution heat-treating involves heating the entire frame up, almost to its melting point and then doing a controlled cool down to normal temperatures. More or less, this makes the frame equally strong at all points. Solution heat-treating is expensive from a time, equipment and skill standpoint and is only found on higher quality bikes. 7000 series tubes are weakened at the weld points because of the heat of welding and this means the tubes need to be made thicker and heavier at the weld zones or the bike is simply inherently weaker than a 6000 series bike of the same weight.

There are also other factors that add or detract from the strength of the frame. Most notably is the way the weld area is finished. An aluminum frame which has very smooth weld areas, like the Cannondales or Giants, have been "wash passed" and/or polished. A wash pass is where the welder runs the electrode over the weld a last time without the welding rod. This causes the weld to flow, rather than have the "waves" commonly seen in lower-end aluminum frames. This combined with a final polishing of the weld, allows the stresses to move freely through the frame and not build up as much at the joint areas. This building up of stresses is why frames almost always crack at a weld joint.

of course, if this is something the kid is going to outgrow anyway, are we really worried that the Viner is going to crack. my vote is for the Viner. of course, assuming you're buying from GVH, you could spend a few hundred more and buy a Cinelli Unica and have a heck of a ride.

Probably a reasonable point. Although there is a very good chance the Viner is actually made in Taiwan and only painted in Italy, if that.
Viners are hand-made in Italy - great frames. (nm)misanthrope

Just from looking at the info on the Unica, it seems that it's made of a 7000-series alum. as well. Have you had experience with Cinellis before? Thanks

The Unica is made from Zonal, a 7000 series tube. As far as I know, Starship is the only 6000 tube in Columbus' range.
