Carbon Bike Seatpost 27.2/31.6 Ultralight Carbon Fiber Bicycle Seat Post Bike Seat Tube for Mountain Road Bikes MTB BMX

I bought a new bike that came with mid-range aluminum bar, stem, and seat post. I replaced all of them with Amazon-sold carbon fiber products that are very cost attractive. This is my fourth such upgrade project, and all have worked out.This TPard seat post arrived quickly, well packed and not very expensive. The diameter is consistent at or very near 27.2 millimeters, within a tenth +/- of a millimeter or so at 10 millimeter intervals. I miked it out of curiosity. It accommodates the Di2 Shimano seat post battery very nicely, has nice markings showing the depth of penetration into the seat tube, and the saddle (seat) mounts are particularly good. The mounts are sturdy, simple to operate, give easy access for angling the saddle for forward/downward or rearward/upward pitch.I'm quite pleased with the seat post and recommend it.

Good quality carbon fiber post with dual-adjust mount. Simple and works great. A bit heavy compared to more expensive brands, but still a good value and lighter than equivalent aluminum posts. I like that it also has the min insert and height markings. My butt's happy.

Wanted a 0* setback post for my zwift bike. This was the same price as similar aluminum posts, so I went with it. It creaks a bit (its not the post moving in the seattube), but it works fine for an indoor bike. I wouldn't trust it if I was using it outside given the noises I've heard from it.

It looks great. I ordered some carbon fiber grip paste to go with this seatpost. I spread a dab of it right where the seatpost clamp grips the post and have not had any problems with slippage. It looks really cool and holds the seat just as well as the original post. I was worried that it might not be long enough, but it's length was actually just about perfect.

This was a breeze to install and set up. Adjustments are easy. I'm new to carbon fiber hardware on my bike and was very careful with usage since I've read some horror stories online for breaks, but this has been solid. Been installed for about two months now, and I've ridden close to 300 miles on it so far. Holding up great!

Great value!

Good quality seat post but I was sent a damaged item. Paint peeling and chipping especially on the top part close to the clamps. I was pretty excited but very disappointed when I received it. Don’t buy. This company does not have good quality control prior to sending their items.

Mind the length. Good quality but mine is at the STOP bar sized to me. 5mm more and it’s too short. Quality is amazing tho
