Suspension seatpost w/ roadbike...(19 posts)

Suspension seatpost w/ roadbike...timfire
Dec 13, 2001 12:41 AM
I was considering getting a suspension seatpost for my roadbike. I do mostly commuting/ street-riding, so I thought a suspension seatpost might take the edge off of not-so friendly roads. Besides the obvious weight-issue, are there any other issues with using a suspension seatpost on a roadbike?

Right now I'm riding an old Schwinn touring bike, but after Christmas I will be getting a 2001 Jamis Quest.

That's what they are for, so not a problem. However, ensure that you get the right one for your weight. They adjust in different ways - some have a rubber type insert that socks up the shock - you need to get the right one (I think they are colour coded). Come to that, I would make sure that you do get an adjustable, as some aren't, and that it has a reasonable range of adjustment - you'll need more give off the road than on it probably - and I would think that you could really damage the old Jap's crackers if you bottomed out on one...

Well, ordinarily I would say that a suspension seatpost is too d@mn heavy for a road bike, but since you are going from one lead-sled to another, I doubt you would notice the extra weight, anyway. Maybe you should get a sprung saddle, too?????

Rusty,

Not sure if the sprung saddle comment was meant is jest, but it is a very good option IMHO.

I have a Brooks Champion Flyer (where do they get the names!) on my MTB. It feels like a regular saddle when sitting on it. The springs are pretty tough to compress just a little by hand.

But when you hit bumps it really takes a lot of the shock off. Plus you get the added bonus of the comfy leather saddle.

Check out wallbike.com

The weight is an issue though. I think mine weighs 1.5 pounds.

I have had a RockShox road post for a little more than a year, and it has been wonderful. I have a Trek 5200, but I also have a twice-surgically-repaired back, (plus, now, a surgically repaired neck).

There are other posts, too, from USE (more expensive) and Kalloy (much less expensive), but I found the RockShox to be the best for me — although at a price ($99 from Performance).

The weight penalty is easily outweighed by the comfort. And it's pretty easy to set once and forget it. There are three of us in our regular weekend ride group who have them. We all hammer it pretty good, too.

Hope this helps.

FWIW,
Mike

PS: Ignore Rusty. The rest of us do.

the Rockshox style will change the distance between the seat and pedals as you ride, which I found to be very annoying on my mtb. You might consider something like the Thudbuster, which doesn't do this, but they are even heavier and might not fit unless you are showing a decent amount of post right now. I recommend fatter tires at lower pressure.

Thank you for that. I was hoping that would be mentioned. Why is it that tires are so often ignored when comfort issues arise? They are the quintessential element of the entire equation on bad roads.

Never mind me....go buy a carbon fork and suspension post...I'm sure all will be well then. Tires schmires right?

Good call gtx.

Cheers!

gotta love 700x25 at 100psi--mmm, comfy nmgtx

Fatter tires weigh too much. ; )

Also, forget frame geometry and it's relevence to rough road performance. NEVER buy a bike that is appropriate to where you intend to actually ride it. Instead always buy a "race bike". Arguments to the contrary are merely heretical hogwash disseminated by Huffy marketing agents.

Cheers!

you should buy a bike that is too small cause it's stiffer and more efficient and you'll go faster. That way, you'll also be sitting too far forward on the bike with lots of weight on your bars--this is where carbon forks and gel padded gloves come in handy. And yes, fat tires are heavy and slow and no one minds on group rides when people get flats on their skinny, overinflated lightweight tires--they all need to stop and stretch out their backs anyway. On fast descents be sure to follow the guy with the twitchy, too small bike, carbon steer tube, whose tires are pumped up to 180psi.

I'm grumpy too. We're in near flash flood conditions and I haven't ridden in two days. :)

Thanks guys, but I have a few more questions. How much post needs to be showing to a use a suspension post (I'm sure it'll vary slightly between brands)? Also, do they slow you down significantly, I mean, I presume that they would steal some of the power from your pedal-ing. Not like I'm racing but I don't neccessarily want to ride slow either. More than anything I'm just curious.

I don't think Rockshox has much of requirement--if it don't work, your frame is probably too big for you. Check the Thudbuster.com site for their specs. Again, I think they are kind of lame for road use, but to each his own. Also, they develop some slop over time and require maintenance.

I think they are kind of lame for road use, but to each his own. In other words, I don't like them (and I explained why), but someone else might like them (and I know that plenty of people do). Gotta weigh the positives against the negatives and make up your own mind. If it works for you, great!

I have a suspension seatpost on my MTB and it was be too long to be used on my road bike. They need to show more than other posts. When I got my new compact geometry frame I could use the suspension seatpost on the road bike and it feels great. Most of the time I didn't feel any effect on performance until I did a fast group ride. I rememmber that after a 4 mile fast section my quads were hurting in a different way than usual, like if the seat would be too low. I was probably bouncing. Since I have tow saddles I can swaps seatpost very fast so I will use the suspension seat post for long endurance rides and recovery rides and the normal one for when I need to go as fast as possible.

I recommend the USE RX post--made for road, lighter than most and short-travel but still soaks up the bumps. Also a susp. post can improve your spin--if you're bouncing you're not spinning smoothly. If it's set up properly there is minimal bounce--I can't even notice movement, but you know it's doing something over the bumps if you go back to a rigid post!
Good enough for Jalabert....CT1 Guy

I've seen photos of Jalabert from the Tour riding with a USE road post - good enough for him.....
