thudbuster >250?

The cane creek thudbuster suspension seatpost has a maximum weight rating of 250. I would like to try it but am 270. Anyone in my range had luck with it or best to stay away?

I've never been a fan of suspension seatposts. I really don't want my seat height and positional relationship to the pedals changing by an inch or more every time I hit a rough patch. I think they decrease pedaling efficiency and have never seen a seat suspension that made a significant difference to riding comfort. They might feel a little cushy, but you will likely be just as sore as if you rode a standard seatpost. If you need suspension, get it in the fork and rear of the bike, not between the seat and the frame. IMHO

Most of the discussion regarding Thudbusters that I've seen has been in the tandem forums. You might get more input over there, but I think they are mainly a stoker thing.

I ride one but I am not in your 'range' as I'm at 185 now. Can I tell the difference after 50 or so miles along the C&O? Absolutely. '
With respect to Myosmith's post. If I am hitting that much of a 'rough patch' I'll be out of the saddle taking the brunt of the hit in my legs.

Of course the frame you ride, the conditions you ride in will all have an impact on the difference you may, or may not, see. As with saddles it's all a crap shoot.

I've never used this particular product, but usually the weight ratings on items is understated by quite a bit to avoid liability. I don't think an extra 20 lbs. will bust the thudbuster.

I used one on a tandem and hated it. Some people really love them though. If you decide to go that route it is really important that you have the proper elasomer in there for your weight otherwise what will happen (if you weight too much) is that when you hit a bump the elasomer will compress with your weight until it suddenly stops. It'll jam the seat right where you don't want it. Not a very comfortable situation. Believe me, I know. I did a 360mile ride like that. It just about killed me.
I would take the weight suggestions seriously with the thudbuster, not because it might break but because you want the suspension to work properly.

Purple elastomer pair in the LT is for the last threshold of acceptable rider weight on those.

I'm right around 200#, and so I got the Black ones on my Bike Friday Pocket Llama..

... perhaps If there is not much exposed seat post you will be OK.
the wall thickness is generous on the 27.2 tube part.
but like aircraft , the fatigue of the metal will have a shorter useful life
in higher stressed situations

The ST all the density ranges of the elastomers are the same color,
so you have to read the packet.#1 to 7 (special order is a #9)
[Max still tops out at 250#]

I got the PDF off the CC website they don't suggest rider weight over 250#
[black/black elastomer set]
and do specify it's a small bump reduction ,
you still have to get off the saddle for the larger shocks..

thanks all. gotta love how CC says "fits any rider's weight" and then shortly thereafter says "max 250". ah well.

I was thinking ST anyway - maybe the #9 special order was close enough.

I tried a big apple on the back today and came away unimpressed. soupy ride but still hard on the real bumps. I'll throw it on front and an ST on back. if that doesn't help, nothing will!

Don't think a sprung Brooks saddle has a weight limit, other than usual metal fatigue.

I've actually heard that the springs on the B67 don't really compress to give much suspension action if you're below 200 and that's not the most heavy duty of the options.

I have a thudbuster st and my weight has been up to around 250 in the past and I had no problems. The thudbuster feels better than my sprung VO saddle imho.

I have not noticed any problems with the suspension affecting my pedal stroke and it really does smooth out the bumps.

I had a thudbuster (longer travel one) on my Xizang for years - loved it. You get used to the feel v quickly. It eats up small bumps well - hit a big bump sitting down and it will catapult you to standing where you should have been anyhow. I sold it with the bike but wish I'd kept it. I bought a second one for the stoker on my tandem.
You should carry a spare elastomer with you - they can split with age (over 5 years in my case) leaving the post unusable. (Luckily when mine split I managed to find the split elastomer and ziptied it all up to get me home). Try it - start with the heaviest elastomers
