Yeah, that position is pretty deep.

In theory they shouldn't be able to tilt under load but I'll see if I can find out any more info about them.

Edit: engineer for our state squad, but the national team overlaps in areas here because the national team is based here.
Wow. I've never heard of the Pivotal system.




According to Dan's Comp (a top BMX parts website):

The Pivotal seat became the BMX industry standard not long after its introduction. The pivotal design requires one-bolt mounting and angular adjustment, and is the most popular option in modern BMX seats.
I could totally see that going main stream for cycling. Or simply make it an option.

Maybe for the track where comfort isn't a high priority, but rails probably won't be getting replaced any time soon on the road.

Dirt jumper and some downhill rider use that system. It is useful when the saddle is tilted backward to have more space to put your hips on top of the rear wheel axle or even behind it during jumps, drops and steep sections.

I would assume they are more like the Selle Italia monolink system or like SDG I-Beam system where micro-adjustment of the saddle angle is still possible but a stronger mono rail to handle better the impact (in case of the SDG I-beam system) compared to a standard railed saddle. But looking again at the picture, it looks like the saddle can pivot on the forward bolt and rear bolt fix the angle of saddle and would have the advantage of always keeping the saddle exactly at the UCI saddle setback limit or at the proper setback specific to each rider.

A quick look suggests our pursuit teams ran them at Rio so it looks to be more than just a sprint thing

I personally think that track equipment should continue to diverge from being hand-me-down from Road or Triathlon Time Trial equipment.

Areas where it has already happened:
- Frames (they are no longer the same geometry)
- Handlebars
- Shoes
- Wheels
- Gloves
- Cranks
- Chainrings/Cogs
- Tires
- Hubs

Areas where that can happen:

- Saddles
- Pedals (how many hacks to attach straps are there now?)
- Skinsuits
- Helmets
- Seatposts
- Aerobars
- Tires
- Shoes
- Gloves
- Power Meters
- Cycling Head Units
- Power file analysis software
- Hubs


Track racing is evolving into a similar but different sport. There are LOTS of opportunities for innovation.

Get this, every Olympics we see a big team make a tweak of something on that list above.

Imagine if a company or two focused time, money, and resources towards doing those things for more than just one team? Sounds crazy but 3T did it with the Scatto bars. CASCO with the WARP helmet. SRM did it with power meter cranks....and all of those are staples of the sport right now.

I sometimes ponder on whether the design of hubs (and bottom brackets) bearings are optimum from the viewpoint of friction. Nice MEng or PhD research project.

You could throw Look and BT in there as well. Despite their developments surrounding their respective national teams, their products are still offered to the public at a premium, although actually realistic and obtainable price. It would be excellent to see the UCI grow some balls and push hard on UKSI and FES to do the same.

I'd be curious to know what the quoted lead time is on UKSI equipment. Not a fluff "well, these things can take a few months or more depending on National Team demands" type of answer. I think that competition equipment should have a stipulation on maximum lead time, just the same way they have a maximum prototype window for products.

Asked my friend about the seats and seat posts over post race refreshments last night.

They were someone's honours project a little before the Olympics, all the saddles are exactly the same for each rider which was justified as they're only on them for 4 minutes or less. So far only one has failed in any way, not sure under who. Printed shell onto billet post/topper block item. Effectively a metal pivotal with some fore aft adjustment but very solidly attached. Small gripper on the front of the saddle is pretty much where the rider sits.

Seatpost is for aero properties, to try and help smooth the turbulent air from the opposite leg at extension, the vanes are slightly angled and apparently not symmetic. Some rider may not use them due to how their knees track during the stroke, knees in changes the desired flow patterns.

All very interesting and I'd like to give one a look over if the opportunity presented itself

Plenty still use normal posts, rails and saddles for training and lesser competitions, see glaetzer on a prologo as usual. I think the fancy ones only get rolled out for serious tournaments where they want to take care of the negligible risk of a saddle moving.

A few of the pursuit guys come out to our local races so I'll see if I can get an opinion on what they're like first hand

I need a better front wheel track skewer than the Zipp one that seems to stiffen up and become impossible to tighten/loosen after a few uses.

Suggestions?

FFWD do one that seems to be pretty widely available

The problem is with the nut. Zipp simply taps an aluminum block to make threads. It can easily be stripped out. I think they chose aluminum to be lighter. A teammate of mine stripped hers out at collegiate nationals 10 mins before her race. Easy to do.

Maybe go to a LBS or Performance Bike and get a budget skewer. You can probably get it for free from a LBS by asking . Those have steel inserts for the threaded area. You may even have one at home. You know the kind of skewer that comes with a home trainer? You just need the nut off of it.

Yeah, when I got it off it seems stripped halfway down the threads. Dammit Zipp!

I have the opportunity to work with a cycling kit company (who sponsors me), who is willing to develop a high end speedsuit, pretty much based on my needs for track.

What are your favourite speedsuits? What are your must-have features for going fast AF?

(I have thoughts of my own, but I'd like y'all's too)

this could probs be a whole thread on its own.

my answer is, first, it depends. if "for track needs" you mean "i'm gonna pull this on and off a few times a week all season long and want it to last for two seasons," then that's a very different track need than, for example, "an extremely aero but possibly fragile skinsuit that i'm saving for my target events and will probably be destroyed by repeated number-pinning."

but in general i'm interested in:
long sleeves
compressive fabric down below to keep everything in place
softer, breathable fabric above for comfort, especially through a hot summer season
long leg grippers
no dang collar
designed/cut for arms to reach forward (instead of designed/cut for arms to hang down at the sides)
no dang wrinkles
good quality chamois

advanced: clear number pocket?

Their FB hasn't been updated since 2015. The website is simply 1 image. It's safe to say that they are not in business right now.

I never saw any bikes after their initial first generation.
