Harsh ride question...(?)(10 posts)

Harsh ride question...(?)BoneDigger
May 29, 2002 9:20 AM
I have a Cannondale R300 from 1998 that is a very stiff and harsh aluminum bike. Long rides will beat you to death. Would replacing the stock cro-moly fork with a carbon fiber one help? How about a carbon fiber seat post? Will cf seatposts hold up to a 200+ pound rider?

Lastly, on a fork, how do you determine the fork rake?

First of all, a carbon fibre fork will dampen the ride quality up front quite a bit, especially if you get a fork that has a carbon steerer tube. A carbon seat post will not give a softer ride from vibration coming off the rear triangle, so some other options can be considered. One is a suspension seatpost. Another is upgrading your tires to 700x25 or 700x27.

The upgrade to a carbon seatpost is more for weight reduction rather than quality of ride. Spend your hard earned money elsewhere, like on a high quality CF fork. I have the Reynolds Ouzo Pro, and I am a big rider. I have have no issues with it.

Good luck.

The carbon fork will help front end harshness and give your hands a break. I suspect the rear end hashness is a larger problem. Like Cima said the carbon post isn't going to do much if anything. Some claim the post makes a slight difference. Most say it has no effect.

I'd go with wider tires first. Maybe a suspension post if it's that harsh a ride.

A carbon fork may help but realize that not all forks are the same. Some CF forks are very stiff while others may be more compliant. Do your homework before you spend the money.

As for the rear end, I couldn't tell any difference between the carbon Campy and the Ti Campy. I opted for the reliability of the Ti post. You may get posts from people telling you that you will be fine but IMO at +200 lbs I would stay away from any lightweight component regardless of the material. Wider tires with a little less than Max pressure should help. Also, a different seat may improve things.

Not all carbon forks are the same; some are quite stiff and others are soft. For example:

Stiff - Kestral EMS, Wound-up, Reynolds Ouzo Pro (medium stiff)

Soft - Look (most models except for newer HSC4), Time, Older Trek, most Taiwan models

Regarding ride quality in general, I suggest using 23c or larger tires, the softest carbon fork your type of riding will tolerate, and maybe a softer seat. The carbon seatpost is a poor value as far as improving ride quality goes.

Enjoy.

Instead of spending $350 on a new CF fork (probably will needed either a threaded fork (good luck) or a new headset and stem since its a fair assumption that your current Canny has a threaded set up) and $100 on a CF post (the comfort benefits of which are dubious at best) consider doing the Cannondale trade in deal - for around $500 you get a brand new CAAD5 frame with a CF fork (I believe made by Time) and a Campy headset. The CAAD4 and newer frames ride far better than the older versions (personal experience).

Stick with te same rake as the OE fork, otherwise you may create some real overlap problems. I used a Profile BRC for some time and it worked great. Just dont buy a CF steer tube'd CF fork.

First, I wouldn't even bother to replace fork. You end up paying alot (headset, fork, labor) and the result is questionable at best. I have steel and CF fork and steel one rides better IMHO. 5$ foam grips (you can put tape on top) or 2-3 layers of tape would make more difference.

Second wider (25-28mm) tires with high TPI and lower pressure make huge difference.

Third wider seat with softer foam (aka Terry Liberator or Nashbar 2x). Nashbar is actually pretty good, only 25$. I have ridden with a few brevet riders who would swear by it.

Forth shoe gel inserts (CVS has many)

Fifth well padded gloves.

Six shorts.

btw how long are your long rides? you may be better off selling your Cdale getting steel bike...
If you had a car?siclmn

If you had a car that rode harshly would you just put better shocks on the front wheels? Or if you had some roller blades that rode harshly would you just put softer wheels on the front? You have aluminum for a frame and that is the problem. Get rid of it. Anything else will be better. You have a frame that does not flex.

I have a R1000 frame same year and weigh 180-210lbs depending on the year. It came with a CF which helps smooth things out. I am have done multiple rides up to 400 miles on it over some pretty bad roads(Terrible Two included). I guess it is just me but, I find the bike enjoyable to ride.
So if you can still get a threaded fork I would go that way. I know Colorado Cyclist had threaded Kestrel forks for around $140. Don't know if they still do though.

Good luck
