Hello, I have a proflex 4500 for 4 years now.

I do not speak good English, I am Swiss and I speak French.

I would like to know if there are breakages of the frame, how many copies there are still running, and know, just for my personal info, how much does today proflex 4500??

I do not intend to sell, I love this bike passion, I find it too good, mine is equipped carbon fork and disc

Tanks

Hello and welcome.
The 4500 is a great frame and is very strong. Frames inserts could wear out with age but I've only ever heard of one frame breaking in use. The main weak point is the seat post insert which can break off level with the carbon.
Show us a photo of your bike with the carbon forks and disc brake. Sounds interesting.

Welcome

That's a REAL nice bike I'm big on the black stealth (no decal)look.

Mmm discs and linked fork.

Hello, thank you
I'd give him a renovation and I look for information on eventual reinforcement resins before applying a varnish to avoid the eventual result of having cracks

I'd then put him spinergy carbon

shimano disc 160mm

A bike like that is probably worth US$3000 today. It is rare, it looks in good condition, and it has good parts.

Do you have more pictures? I would like to see the fork and the discs in detail.

proflexsuisse · « **Reply #6 on:** December 13, 2012, 01:49:14 pm »

the disc are simple, but effective, it was a quick choice because I had run and I had to put the fork.

It has no cracks, for almost 15 years.
I think soon restore the disassembled for sanding, then I would treat the slight impact (on varnish) of the year, which serront treaty glue epoxy, then sanded to be bi-component varnish varnish and sanded with 1400 grains has water for polishing

I would like to subsequently equip it spinergy carbon, a saddle and a handlebar carbon carbon, according to the means

That's a really nice looking bike you have. I would really love to have Those forks. There are plenty of people on here who have 4500's myself included. One of mine is in Readers rides and the other I am builing now.

I would not use carbon wheels. Wheels directly impact the ground, often at oblique angles, and that can cause very sharp and unpredictable stress on the wheels. When a carbon-fiber wheel is overloaded, it will shatter instead of bending, so a carbon-fiber wheel needs to be much stronger to avoid any chance of breaking and causing a crash. A very strong carbon-fiber wheel will weigh the same as an aluminum wheel.

thank you.
Can you give me the weight of the frame?

I'd give him a light fitting
I think he put

a saddle carbon and new transmission carbon

fyrstormer · « **Reply #10 on:** December 16, 2012, 12:32:10 am »

Sorry, I don't know the frame weight.

I wouldn't use carbon-fiber brakes either. Carbon-fiber is good for parts that need to be very stiff, and are not subjected to impact or friction. Impact and friction will damage carbon-fiber very quickly.

Which is more important? To make the bike a few grams lighter, or to keep the bike safe? If those carbon-fiber brakes are damaged, they will shatter, and you will have no brakes left. You know if this happens, it will happen on a steep hill.

If you do use the carbon-fiber brakes, make sure to tighten the brake bolts EXTREMELY carefully. Too tight, and the carbon-fiber will crack.

Hello, this is not that the carbon fiber, but silicon carbide, ceramic and carbon fiber

labaratoire is tested in real test

This is a new product which will be released early January 2013

This is done with the characteristics of a disc brake

I have an unbuilt 4500 frame but no scales to weigh it. I'll try and find some scales this week.

Here you go, according to the K2 tech sheet they weigh 2.85lb.

Formular one and moto GP use 'carbon' discs, are they the same as those? The only problem they seem to have is that they dont work untill they are hot and they loose there heat quickly. So down hill riding might be good but XC riding maybe not so?
