    I'm looking at getting a Thudbuster ST seat post to help smooth out my commute. Has anyone used one? And could anyone maybe recommend something different? I chose this one purely based on the good reviews.

    Thanks

    I have a CG-R seatpost on my Roubaix and find it takes a lot of bumps and buzz before it gets to me without sacrificing power, only comes in 27.2 though

    Thanks for the reply. Unfortunately, I need a 31.6 post.

    I'm currently running 700 x 38c Schwalbe Marathon Plus. Can't get anything bigger. :(

    What pressure are you running them at, I have 28's on at 80 psi and they are very comfortable so 38's might go down as low as 40 psi

    You can get a seatpost shim that will allow you to fit a smaller diameter post into the seat tube.

    Also consider a Canyon VLCS seatpost - much lighter and has some good reviews online.

    Those have terrible ride quality. The sidewall protection is excessive. There are some other Marathons with the same level of tread protection but more compliant sidewalls.

    I’m running them at 60psi at the moment. I was running them at 50psi, but because I’m a little heavy, they almost look flat when riding.

    Thanks, I’ll look into both of those options. :)

    Really? I’ve honestly found these tyres very good. Though my experience with other tyres is limited.

    The fact that you're adding suspension to 38mm tyres for road use suggests your tyres are a problem, or you have the world's most sensitive perinueum :pac:

    Ha! While my posterior is a little sensitive, my commute consists of poorly maintained country roads and a Greenway. So not the smoothest of rides! My commute is about 32miles a day, so every bit of comfort helps. :)

    Schwalbe Marathon Supreme or Vittoria Voyager Hyper. I've ridden the Vittorias for around 3 years now, off road, on greenways and worse and on Irish country roads. Really nice tyre at around 45-50psi.

    Doesn't sound like a route that requires marathon plus tyres; while schwalbe ones might be risky Durano wouldn't be the worst compromise.

    I've ridden a lot on really poor roads with race tyres without issue.

    Supple sidewalls and lower pressure should sort you.

    Is your ebike limited?

    Ah, an e-bike. Maybe worth disclosing up front as it changes things a bit.

    e-bikes without suspension have a lot of unsprung mass which messes with the ride quality.

    The motor cuts off at just over 26kph

    The roads I travel wouldn’t be as rough as the pic in your post, they’re just your average country back roads. The Waterford Greenway is pretty smooth, but can get a little bumpy the closer you get to the city.
