Time Trial / Time Trialling / TT

Thanks for all the saddle info - a big part of it is discovering which options are available. Thanks for all the offers, @Pifko and @skinny, pms incoming. @danstuff thanks for the offer but I'll save looking at dash saddles until I've exhausted the cheaper options - I don't want to give myself any more excuses to spend money.

Anyone know if you can remove derailleur and re-rivet it?

@skinny I'm interested in this too as I currently have a useless front-mech hanger. The best answer I've so far received is "I don't see why not" which didn't sound very reassuring...

Bonded too apparently.

I'll probably leave it, for the 1w it'll cost me.

I believe the FD braze on mounts on the P2/P3 are glued on under the rivets.
I'm just gonna leave mine on.

Seatpost stopped slipping?

I’d be interested in the Bontrager if @ewanmac doesn’t want it.

No problem, will wait to see if @ewanmac wants it or not first, then will get in touch ;)

Project Fatty9

Pushed the FD Di2 cable into the extension so it's out of the air now. What watts will that weduce?

No slipped again last weekend. Gone back to shimming it with coke can. That lasted a long time before it slipped last time.

Don't you need a small ring, to get the load moving.

I ran a 58 before it was cool... noob

I think the carbon ring I have now is a 57. I've not fitted it to this setup. Still waiting for chainguide - think it's at the post office.

Fabricate a teardrop shaped nut/bolt to go behind it?

Yes, drilled the rivets and slid a blade under it to break the bond. About half way through it gave, taking a patch of lacquer (no larger than the mount): using a flat blade to work around a curved mount/frame levered it off. You could probably avoid this by working from either side alternately.

I've also ground the hanger part of the mount off (on a Felt I think), just leaving the base. But obviously that's a one-way street.

The frame is chipped and scratched all over, would just add to the character.

I think I'll leave it on, I do like ridings spocos so would only have to put it back on. If I loose an event by 1 second I'll regret that!

Ha. One idea. Go ful Nik b or whatever his name was, like in the 12.

@skinny @ewanmac

Apologies: wrangling a number of bikes over a period of time has blurred my memory.

I did remove the hanger from a Felt. And I did refit it. The patch of lacquer (which remained bonded to the mount) was actually useful as it ensured the mount located in exactly the same position.

I cut a piece of self-adhesive vinyl to cover the bare patch during the interim and two-part epoxy and an eBay rivet gun to remount.

Thanks. Maybe I'll do it. I'll see how the new chainring performs this weekend before deciding.

Aeox and Jet 9+ successfully tubelessed.

Eventually.

Empty CO2 cartridges, a hacked Coke bottle and a sticky floor, are testament to the struggle.

Yeah, not for me thx.

They're not for me either... :0

Even though I've done one and it worked as expected I just don't get tubeless for road use. Especially when the TLR tyres test faster with latex inner tubes.

So... The same

Tyre talk reminds me I need to fit my new fast tyres for saturday.

Three tests, two are the same, one is faster.

The tubed version is the top tyre in his list so my point stands.
