Tester's T3

Red tyres plz.

Didn't you listen to the TT Podcast? Black is faster.

faster

Fasterer?

15T sprocket, ready for whenever I eventually decide to go racing. With a bit of luck I'll have a 56T ring ready by the time I want to up the gear. Next generation cup washers will be 1mm shorter so that the bolts are properly flush #aeroiseverything :-)

Still on the Zipps?

Still on the Zipps?

Back on the Zipps since the end of July last year. I didn't feel that I was getting anywhere with the short cranks, 25th July I was 13:02 behind Boyman with short cranks, 15th August I was 11:48 behind him back on the long Zipps.

Sorely tempted to troll Tarmac by getting sticky dots to smooth over the Torx™ recess :-)

Nothing to do with your CP, but seeing as it concerns your handiwork for a Cervélo mounted Omega, this seemed as good a place to ask as any.

Rob's sent me one of the integrated bearing cover cable hangers you had made, but unfortunately he was having an off-day and tightened it too far, snapping one end.

I was going to use two-part Epoxy for the repair and thought that even with only modest torque through the screw, it will stay inline with the fork on account of the Ventus above.

Am I rite?

Sounds a bit dodgy. The clamping action is there to stop it tilting and affecting your headset preload when you apply the brake, and the completion of the hoop around the steerer stops the hanger from pulling forward and splaying under brake load. Show me the break and I'll run the FEA with it in the damaged condition and see what happens.

Thanks, most kind!

Well, I've learned something in the last hour, which is that I need better simulation software than is included in Fusion360. I saw some cool stuff a week or two ago which might have worked for the case of a component where the pre-stress is a critical part of the function (which would, as a separate matter, be brilliant for doing wire spoked wheel design)

tl;dr: I'm not able to predict exactly how the hanger will react to having been broken and then glued back together, but I wouldn't ride it like that.

I much appreciate your time and trouble either way.

Slam-dat-stem bearing cover order incoming...

Somebody needs to correct Nick Salazar's error and make an Omega X back plate which fits the old P2/P3 head tube...

You don't fancy the job?

I don't think many people would fancy the price

@mdcc_tester do you have a recent drive side photo? Would be interested to see 🤓

do you have a recent drive side photo?

No. I'll try to remember to take one next time I get it out. With a bit of luck there might be one or two tweaks before the first outing.

Do you use the standard brackets for attaching the extensions?
I have just got a set of Ventus mk1 bars and would ideally like to replace them with something that held the pads at 90degrees to the risers... Wondering if you know if any of the other 3t brackets fit

Rob Barrett (Nutshell on TTF, Float Aero) is using some alternative way of mounting the elbow cups on his Ventus, can't remember whether it's 3T or Zipp parts.

Thanks

Looks like you can use these: https://store.3tcycling.com/en/spare-parts/aerobars/clamp-conversion-kit-on-basebar-164.html

Look far more robust and closer to a 90degree angle

closer to a 90degree angle

I don't think they are.

The anhedral on the elbow cup mating surface of the Ventus has annoyed me ever since I got them, but obviously never quite enough to get around to doing anything about it. Any simple solution (i.e. a wedge) has the disadvantage of adding more stack height between the extensions and the cups, and I like the close-coupled cup/extension more than I hate the anhedral. If I wanted to throw a pile of money at it, I have an idea for an epically #tartmode top clamp set with an integral bridge, which would solve the anhedral issue and the twisting about the vertical axis.

Kingswan on TTF has built something that removes the angle on the Ventus pads with then makes them compatible with other makes of pad (http://www.timetriallingforum.co.uk/index.php?/topic/120877-aero-bar-wedges-to-angle-the-aero-pads-up/&). Is that what you're looking for?

I found that thread because I was looking for something to angle the pads on the Ventus IIs and it looks to me like he's developing something for that too, however it adds stack which I'd like to avoid.
