|Carbon upgrades for comfort||CrankE|

|I'm currently riding an '01 Klein Quantum Race with the original Icon bars and post. The bike fits very well and I am considering moving to an Easton carbon post and bar to soften the relatively harsh ride of the Klein frame & fork. Will this switch provide the desired effect? How would an all carbon fork affect the ride?
Is Easton the way to go, or is there a 'better' setup for similar money?

|I'm not sure about your upgrade effectiveness since I've used these as a new bike build on a LOOK KG461 build up, but.
Easton EC90 bar: Very comfy. I have the 31.8. No flex in the hoods, minor in the drops, noticable on the bar ends. I'm having some minor trouble with bar tape sliding around (Cinelli Gel), probably need to use some light adhesive and re-wrap. Could be due to the smooth surface of the epoxy coating.
EC-70 post = DANGER! I had the head snap off of mine after 6 weeks. Almost no epoxy holding the post together. I had stopped to strip a layer. I stood for a few revolutions, clipped in, sat down and BOOM! The whole headpiece snapped off; the saddle saved the twigs and berries from any damage. I have been using a Deda blackstick for 3 months now w/o incident.
Fork: Unkonwn. Stock HSC3 LOOK fork with my frame. Can't help here.

|I too have an '01 Quantum Race. I had been thinking of a new bike, but decided to upgrade the "control" points to get some more life (and fun) out of it.
Seatpost: swapped the stock Thomson for an Easton XC90. Yes, I had to use a 27.2 to 31.6 shim, which basically negated any weight savings; but I didn't care. I had read a bike review article in one of the pro cycling mags which had a negative comment about a particular frame using such a large diameter seat tube, implying that the respective seatpost was thereby so stiff. Despite what you read elsewhere about carbon seatposts not making any difference, I noticed a difference 1 km down the road I ride almost every day. A noticable "muteness" without any sense of flex. (I kept same seat, so it is an apples-to-apples.) I felt this was a worthy upgrade. Note that I would recommend the XC90 over XC70 because you get more length of carbon outside the frame (all-carbon vs. just the post) and the above mentioned narrower diameter.
Bars: First off, I was also changing the stem to get a better fit. I had to obtain the 1 1/16 to 1 1/8 shim from a Trek dealer to convert the new stem to the whacky steerer diameter on the Klein. I chose a Stella Azzurra Vice-Versa Mg stem and a Modolo KX Curvissimo bars. (Disclaimer: these cost way too much, but I was rationalizing how much less they were than a new bike and I was able to get a really killer deal on the combo.) Again, first 1 km and I noticed a difference. The first thing was how little flex there was in the bars. I never believed the stock to have any flex, until i road these. It is hard to describe the sensation, but it was there. I don't know how much was attributed the stem and how much the bars, but I do know that Mg stems are suppossedly stiffer than Al; I also know the CX bar to be considered pretty stiff. What is also pretty amazing is that while feeling stiffer, it also exuded the same muteness of the road. I distinctly recall that first km thinking, "wow, this was a worthy upgrade" and how the bike felt simultaneously more lively and comfortable. My description: "stiff butter"
Some may claim it's all in my head. Of course, what's in your head is all that matters anyhow, but I believe that when you spend hours and hours on your bike (over 2,000 miles this year so far), you pick up subtle differences intuitively.
Note: make sure any new parts you get create the right fit. I was professionally fitted to my bike first and the new parts executed some of the recommended adjustments (particularly raising the bars: i went to a 10 degree rise stem). better fit can accomplish even more than new-fangled parts.

|Most people run their tires too hard anyway, and get minimal reduction in rolling friction for it. If you're running much over 7 bar/100 psi, then cut it back and enjoy the ride. If you get pinch flats at this pressure, then you need bigger tires or to ride more carefully (or both). You'll get a lot more comfort from lower tire pressure than you ever could from carbon bars/post. Some claim noticeable improvement with a carbon post, while the majority say they can't tell the difference. Princess and the pea?|

|Saw your post, and mention of harsh ride. I am seriously consdiereing the q pro carbon. Do u think i will experince as harsh a ride as the 01 Quantum Race? Any info would be great.
