Home repair stand - D-shaped Carbon Seatpost

Notices
Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

Home repair stand - D-shaped Carbon Seatpost

Hi There,

For basic home repairs, would I be best to use a Euro style stand (like the Feedback Sports Sprint) that holds the axle, or would a more traditional style clamp mount do?

Thanks!

For the bike you have now, the Sprint is a great choice. Park Tool also make a version. The other option though ends up costing more is to by a traditional stand and the purchase the Hirobel from Silca. That way you can leave the front wheel on the bike which is useful when doing front brake work. You never want to clamp a carbon frame. Another option is the Pro Elite style and hang the bike from the saddle but it is very stable that way.

I own the Sprint for my carbon bike and the Pro Elite for my custom steel bike and a heavier duty Cinelli stand for my Rivendell (The Pro Elite doesn't handle bikes in the 30 pound rage very well.)

Thanks. I have the Sprint now and had the Pro Elite before. Guess Ill just have to get used to removing the front wheel

I don't see a problem using a traditional stand with a seatpost clamp, just don't over tighten it.

The worst that can happen is you damage the seatpost which is better than the frame.

I have never looked at that way but it makes perfect sense, thanks for pointing that out. I don't know how well the Pro Elite clamping system works on D shaped posts like the OP has, do you have experience with this you can share?

I have a Hirobel attachment that I use with my Feedback stand. Works great. I had no issue with it on a round seat post, but I was a little more leery clamping my Domane seat post. It might be perfectly fine, but this gives me peace of mind.

I use the same Hirobel others have mentioned on my Trek Domane carbo bike. On my work stand I would normally clamp to the top tube before I had a carbon bike.

I have a Jamis Renegade steel gravel bike that has a carbon seat post. I just had that seat post fracture while riding, after under 2k miles of riding. Jamis replaced it for free, and I had never clamped onto it or exceeded the torque spec on the seat post clamp, but I definitely recommend not assuming weakening a carbon seat post is not a big deal!

You've been around here since 2002 and still haven't realized the issue with double posting?

90% of the time I just hang the saddle nose over the stand's clamp arm.

The other 10%, I clamp the seat tube, which has the seatpost inside it which, we hear, is designed to be clamped.

If I had a D shaped seatpost, would likely do the same.

I have a Feedback stand and clamp my wife's Liv Brava with a D-shaped post all the time.

I don't have any real experience with Feedback stands but I have put D-shaped posts in Park Stands with no real issue. A lot of people are scared of their seatposts but you have it clamped in the frame all the time so if you are going to clamp somewhere that is the place but if you do have an odd shaped post you may need some sort of adapter for that stand.

I ended up getting the Park PCS 10.2. So far so good and I am able to fully control how tight the clamp is around the D-shaped seatpost!

This is what I do too. Although I wouldn't attempt any high torque load work like bottom bracket removal -- not that I have the skills or tools to do so.

I clamp the d-shaped posts on my SL6 and SL7, I've done BB work on both while hanging from the stand. No issues. Carbon posts are strong. As stated above, they are designed to be clamped.

I'm not doing that either. For me its just quick adjustments and cleaning.

Both my LBS (pre-pandemic) and I (nowadays) clamp my carbon fiber seat post for maintenance, and so far (touch wood) no issues. Like many said above, seat posts are designed to be clamped. To add to that, the seat post clamp that holds up your seat post has a smaller clamping surface area and higher clamping force than what you would use on the work stand.

The Sprint Stand works great. We have one that we take for travel.

That, or Silca has a nifty gadget that would work well too and may be the smart way to go about it anyhow.

I use the Park 10.2 and it worked fine for my recent BB removal. For a precaution I had my wife hold the frame while I hammered out the pressfit but it seemed unnecessary.

Park did a video on this. Said it was at least 1000lb of force vs. Only 60lb or so from the stand.

BMC actually recommends clamping by the seatpost! That solves that

Well BMC stands for Bring More Cash so that fits their recommendation.

Good to know. Perhaps this is stating the obvious, but asking my wife to hold my bike defeats the purpose of owning a work stand. Also, a work stand never questions why I am working on my bike again when "it seems fine."
