|This Pro Dyneema post has one of the easiest to use seat clamps I've laid hands on.
Well, there is a new (ish) game in town for carbon fiber. It is called Dyneema. It is claimed to be the world's strongest fiber. It makes ropes better, protects police from stab and gunshot wounds, and is used in aerospace applications. Now Shimano has it and is using it in seat posts and handle bars.
Shimano sent me a PRO Dyneema post in the 27.2mm size to use on one of my gravel bikes in a review for RidingGravel.com. Note- I was not paid for this blog-post, and Shimano/Pro did not request that I do this. I did not purchase the seat post. I decided to put it on the Noble Bikes GX5 which already has a few PRO components, also being reviewed for Riding Gravel. Unfortunately, I cannot say a whole lot about this stuff yet, because, well......Winter. When things get back to a more ridable state, I'll be out on this stuff.
So......Dyneema? Yeah, supposedly it can be used as "hybridization" material with carbon fiber, making it more impact resistant, and possibly even lighter. (See the science discussed here) So, bicycles would seem to be a great application for this hybridized Carbon/Dyneema material. The bicycle industry is not only interested in light weight and strength, but vibration reduction as well. So, Dyneema supposedly helps here. This post from PRO, as an example, can be made lightweight, (my example weighed in at 218 grams), but it can be made to have thicker walls which then can be allowed to flex more without damage or breaking. In fact, this post has a claimed 10mm of deflection with the rider onboard.
Now, all that is cool, but one of my pet peeves, when it comes to saddles and seat posts, is installing a seat on a seat post. Most of the time this task can be a curse word fest and in some cases you have to disassemble the entire seat post clamp just to install a saddle. Well, this PRO post is the polar opposite of that. In fact, I would go so far as to say that seat installation was easy with this post. I don't say that lightly either.
Anyway, I have only been able to cruise the snow/ice free zone in front of Guitar Ted Productions' headquarters and while that isn't much to go on, I can say things look promising here. (We have some pretty crappy pavement out front here) That and the fact that this carbon post flexes and is claimed to be stronger, well, that goes a long way with me. I've broken a carbon post before, and while I escaped injury, I do not want to tempt fate twice. (Thus the Ti Regulators and aluminum posts on most of my bikes)
