As I said, it’s a matter of perspective. If the difference between first and second place is six seconds, and you’re actually competing for first or second, then of course it’s significant. I don’t often find myself in that situation. How many of us do?
I love how these threads always turn into a debate of weight vs speed vs aerodynamics. The person did not ask if they were faster, more aero or any of the crap that you are talking about. He just wanted to know what a good weight for a tri bike is.
Bigsky17. To answer your original question, I would say that 4 pounds is on the heavy side. Like I mentioned before, my Dual is around 3 pounds, I know that most of the Cervelo’s are around that weight. Of course you could go with the new Scott Plasma and get down to around 2 pounds.
no, he wanted to know if it was worth it to invest in lightening his bike (adding an easton for to drop 0.5lbs)…

my P3sl is right under 18 lbs with pedals, spare tire, disc and all that junk. I think that’s a pretty light full blown tri bike. I’d consider anything under 3.5 lbs for the frame very light.
Bisbee prologue probably not the best for a full aero bike, I certainly didnt notice any in the last three years i raced it in Masters or in Pro 1/2. My average up that prologue was under 12mph, even the pro’s werent going a lot over 12. Redlands you see a lot of aero bikes and the Gila TT is certainly fast enough for one (that is what I will be using there next year)
I believe Kraig Willet in biketechreview broke it down that if your average is over about 12mph then use aero wheels, if it is over 17mph then use a disc. That was assuming that the aero wheels weight a pound more than their lightweight non aero cousins and the disc adds a pound over the aero wheels.
The problem usually is that lighter usually costs aero, a Scott Plasma might be lighter than a P3 but I seriously doubt it is as aerodynamic. A set of lightweight Obermyers weigh 1/2 lb less than 404’s but they give up on the aerodynamics. It is a matter of looking at the course. The Lotus sport was one of the most aero frames made but weighed about 5lb (from memory).
I would consider a good weight to be about the 3lb mark, but all “aero” frames are not created equal so consider your preferred courses when making a decision.
OK so I may have muddied the water by asling about the forks. But:
Actually, if you read my original post it asks among Tri frames which are considerd light and which are considered heavy.
Obviously weight does matter or we would all be riding Steel bikes. I don’t think that weight matters all that much for anyone not earning their paycheck by turning the pedals.
Will a bike that weighs 16 lbs instead of 22 lbs mean that I can summit old stage at Boulder next year with out blowing up? No, my winter training is what is going to determine that.
I just wanted to know, relative to one another, if say a Blade (or Tequillo, or B2 or C’dale or Leader or what ever) was heavy for a Tri bike.
“The person did not ask if they were faster, more aero or any of the crap that you are talking about.”
If you’re going to bitch about posts wandering off from the initial post’s topic, then you’ve got a lot of work to do. Furthermore, I think someone already answered his question, so can we not engage in a friendly discussion about related issues? That, or maybe it’s just time for a “Should I shave my legs?” post.
I stopped shaving my legs a while ago. I guess I could shave some weight that way as well. I am pretty hairy right now so I am sure that I could save at least 100g.
It’s funny how there is a group of people on this forum that has to trumpet how “aero is better than light” every chance they get! The poster didn’t ask about that… he simply asked what some of the TT frames weighed and how weight could be shaved. Why don’t you shut up about your weight versus aero opinions until someone asks for it. Are you stupid? Do you not realize if you can get aero AND light,it is better,period!
right on…
g
seriously, did anyone actually READ the original post???
"looks like you can shave .5 lbs by going with an easton EC 90 Aero’
it was about both - aero and light…
don’t like the thread? don’t like the topic?
DON’T FRIGGIN READ IT
“Why don’t you shut up about your weight versus aero opinions until someone asks for it.”
Did anyone ask for yours?
“Do you not realize if you can get aero AND light, it is better, period!”
“Are you stupid?”
I think you might ask yourself the same question.
That is what I was trying to say but I wanted to be more polite but hey I agree fully.
I am switching over my Cervelo fork on my Dual to a new Easton EC90 Aero and I think the difference is around 200g. The Dual carbon fork was about 530g and the Easton is about 340 or a bit lighter. Can not remember the exact weights. The weight is after being cut down.
Otherwise, it’s not a big deal, as the recent hour record rider demonstrated by using a heavy disc wheel.
Here he is - no disc wheel since that would have contravened the athlete’s hour regulations:
How about the next time we need to know if we’re on or off topic we give you guys a call. Ok with you?
so, despite your previous posts, you actually do believe that weight matters (all aero being equivalant)…
althought I doubt ~I~ would chose THAT fork…

You’re right. Strike “disk” from that sentence. The argument is the same.
Agreed. How many times do people need to go through this?
