Suspension Seatposts / Susser Posts / Bouncy Seatpost

Cool cool. I'll be using a steel railed saddle so can horse it up with nary a care about damaging rails or anything so hopefully that keeps it in place!

Yeah, no carbon rails in my world!

Looking to dip my toes in the world of bouncy posts!
Anyone got any feed back on the use vybe? Looks simplest of all and tuneable.
Main use is for audax and touring. I know it can’t make a saddle more comfortable- my butt hurts on some Zwift rides with obvs no bumping- but hope it will help with tenderness on day 3+. After a few days it’s amazing how much more weight I put on saddle due to tired legs.
How do you all deal with saddle bags etc? I normally use a Carradice bagman - will it be a problem? Or a bike packing bag etc? Or is it olde world rack and panniers?
Me and my butt would appreciate your advice!

My Viscacha works with my eeSilk but the bigger Thudbuster posts might be a problem (I've not tried yet). No idea about Carradice, I'm trying to hold off on becoming "full audax" for a bit longer.

As for their function - I rate them. I didn't notice much difference going from VCLS split post to eeSilk but I certainly did when I rode without the eeSilk again.

I'm going to install a Thudbuster on my Surly. I was hoping to ride a bunch this weekend but the physio said I shouldn't, the doc today might have a different opinion.

I did a couple longish (for me) rides with the telescopic Trans X dropper/suspension post on my new Spa Rove and found it made the Cambium saddle, which I’d normally find pretty comfortable anyway, exceptionally comfy. It was a new build so could just have been a good set up but I did another ride the other day and have removed the Trans X post as it has a lot of rotational play and have fitted a rigid post while I wait on the Thudbuster to arrive and my arse was defo a bit less happy.

I did use my Carradice, which I have on a Classic Rack, with the Trans X post but only on a shorter ride. It worked fine. No noticeable effect on the suspension action. That said, being a dropper post with suspension, that post doesn’t very often get compressed all the way down so I didn’t have to worry about the strap that holds the rack in place getting pinched or anything. I’m hoping that with the Thudbuster I can just run the strap around the front of the parallelogram but remains to be seen if that dimension changes as the post compresses. Maybe I’ll swap the static strap for an elastic bungee or something.

I’d guess with the Bagman you’ll be absolutely fine.

Maybe worth mentioning but the reason I didn’t go for a USE or other telescopic post is that I want to get away from that rotational play that you get with dropper posts. Maybe the USE doesn’t suffer from this though? It’s certainly been around long enough that they could have refined the design to remove it?

The other two bits arrived.

This is the newer version seatpost with the single side clamp that needs 16Nm and will definitely be stripped and a Redshift 90mm stem I think which I'm hoping the muppets off ebay followed the instructions when installing and didn't bust any internals.

Thanks for reply. Gunna do it - go for use I think. Also because I am cheap and always end up buying twice. Rotation play- that a thing to worry about on suspension posts?
Set up - how do you account for sag? Trial and error?
Other point I like with USE is the reach is same with bounce. Do you notice the backward movement on thudbuster?
I guess I need to just do it and feedback rather than getting others to do it for me!

This is the newer version seatpost with the single side clamp that needs 16Nm

Seems weird that CC would change from a rock solid clamping design to one that needs so much torque to hold it in place

looks similar to the Suntour clamp

Probably cheaper and 'neater'.

Which usually equals worse. But this ain't new in bike world™

Maybe it was the rotational play made your saddle more comfier........?

Interesting thought.

My G4 ST arrived yesterday but I need the shim to come before I can get it fitted to my Spa.

I did give it a quick try on another bike that takes a 27.2 post and the clamp seems alright. It moved once but I clearly hadn't tightened it properly, or maybe it was sort of 'settling in'? Either way, after nipping it up again it held in place while I bounced on the seat with my feet off the pedals.

Have you had much chance to test the post?

I'm thinking of getting another sus post, but am undecided between the 50mm G4 ST Thudbuster or the sleeker looking 35mm eeSilk + with a more 'normal' twin bolt clamp

I'm just using a regular alu post for a while, to see if I miss having the dropper

How far are you from W5? I have two Thudbusters sat here doing nothing you could borrow.

I do like my eeSilk on the road bike. I was going to get the eeSilk+ for the Surly but £50 second hand for the Thudbuster beats £200 or whatever for the eeSilk.

Thanks, I'm working on the Essex border this week, so probably not too convenient

I did have the old LT version for about a year and found it worked really well. I only sold it at the time as it had a fair bit of setback and combined with the Talbot's slack seat tube wasn't the best position wise

How have the bushings held up on your eeSilk, as they must be smaller than on the Thudbuster?

I've never touched the eeSilk apart from the first ride when it lost the bolt. I mean, I probably cleaned it if I swapped a saddle or whatever but certainly it hasn't been serviced. Road bike though so less grit than off-road.

Aye, been meaning to post in here actually.

It was a bit funny fitting the Thudbuster, definitely can't feel it working as much as I could the telescopic one, despite a very similar amount of travel. I've had to reach down and hold the parallelogram to reassure myself that it's actually doing anything.

It does however smooth things out very well and a 64mile mixed terrain ride at the weekend left me with a very comfy arse.

Only had one bit of noise/movement out of the G4 clamp and that was when I rode through a pothole while going no hands so I've no complaints there.

I'd likely run a rear guard when things are mucky. I do that with the dropper too, so it needs less attention

Smart.

I hate mudguards though so I'd rather just cover everything in shit and kill it sooner than stick a mudguard on. Fuckin' ave it, dropper caaaant

Ah I hate maintenance more than guards, and I also enjoy playing in the mud without looking like I've shat myself

Makes it kind of obvious when I have shat myself though...

Thanks, they are very comfy, yet in a far less noticeable way compared to telescopic posts, which I never really got on with, as I'm really fussy about saddle height

Glad to hear the clamp's not slipped!

I've got two fixes for ya:

don't maintain, ride it until it dies then whinge about it on the internet before replacing with the latest and greatest.

don't ride in the mud

don't ride in the mud

I have no desire to emigrate, so that's never gonna happen

Just ride turbo and watch MTB videos.

Slippery mud is the one mtb thing I'm any good at

I should fix my turbo laptop before winter :-(
