Acliff’s all element stable - Carbon, Titanium, Aluminium, Steel

Slow puncture overnight, so good opportunity to put some Vittoria latex tubes instead.
Veloflex record tyres now patched up with duct tape as there is no puncture protection to speak of...

Sunrise at 8:33am, bit annoying as I was ready to leave for a ride at 7:30...
Beautiful though!

Wow, nice scenery indeed! And nice bikes.

It’s pretty nice around the in-laws in Normandy! Found a nice local climb, starting at the beach, ascending up a car restricted road, great for hill climb practice!

you have great bikes but that argos is my fav .. mainly because of 7800

Actually it’s currently Ultegra 6600 #shame

I generously loaded wife’s bikes with 7800, and currently running a cx70 compact so I can have the Powertap C1 powermeter (not really a looker)

Got a set of 130bcd sram red exogram cranks with the hidden bolt. I don’t have the bolts.
How complicated is it going to be putting a single chainring on it? (Track chainring).

I’ve seen the pic of Calum Brown’s destroyed crankset, and obviously don’t want to have that issue, don’t have his power of course.

Looks like I need the exogram hidden bolt with the washer it comes with, in addition to 4 single ring bolts (or normal with spacers) and another spacer for the hidden bolt to take up the slack from lack of second ring? Also the ring to be mounted in the inner ring position to improve chain line?

Fork update on the Pre Cursa, ahead of a Langster Pro arriving (need to make more space in the garage!)

Alpina Wing TT, looks better on the frame, the Columbus tusk had a weird headtube fork transition.

And with drop bars:

https://www.tubolito.com/ to save a few more grams.

They are excellent to bring along as spares as well since they're tiny!

30 euros tho.

Mega light, but how would rolling resistance compare with a lightweight latex tube?
Could buy 3 challenge latex tubes for the same price...

Al MTB tests (other than the Youtube vid) but you get the idea.

I love them, I have used latex tubes in the past and my main pain is that they deflate rapidly plus sensitive in terms of punctures.

In other news, building up a Langster Pro 2016 to replace the Dolan.
My bike stable seems to be changing over to Specialized, with now an S Works Venge, Allez Sprint, Transition comp TT, and now a Langster.

Basically the same geometry which suits me well and aero shape but for different purposes.

For posterity, as no one on the internet seems to know the Langster Pro’s weight:

49cm frame: 1667g
Cut down fork: 573g!!!
Seatpost collar: 32g
Cut down seatpost 181g
Headset bearings and dust cover: 52g

Plan is to pair with the Alpina Wing TT drilled fork (367g) to max out the aero, and make an aeroish fixed hill climb/TT/track bike.

Build to include:
Silver 48t omnium
Hylix carbon bullhorns
Vision TT brake lever
Giant SLR carbon stem/or Deda Superleggero/Ritchey WCS
Planet X CNC front brake or Tririg Omega

Will use the novatec x openpro fixed wheels for now, with fixed wheelset advice welcome.

Current guise - 7.87kg

Got a Hylix bullhorn bar delivered, anyone else have much experience with them?

Looked to be 22.2mm external at the bar end, but my vision lever refuses to go over and clamp. Also the internal part isn’t round, and pretty rough, so not sure an expanding wedge lever will fit either...

Updated bars, currently awaiting some American Classic 420 aero track wheels and gp4000s.
Bars need to be slightly rotated up.
Tried to acetone the Giant logo off, but it was being stubborn. -15 degrees stem is rare and fits the bike pretty well though.
Probably could do with 110mm-120mm stem.

so the skewer/bike was not in the turbo tight enough and popped out damaging the stays?

THE WATTS

Appears so, though i’m sure the skewer was tight when I put the bike on the trainer yesterday...

Anyone be able to comment on whether the damage looks superficial or whether I should be concerned about the structure?

Doesn’t appear that there are any visible cracks, it’s a fairly deep scrape though on the edge of the seat stay...

Particularly annoying is that the turbo didn’t record more than 900w, I was expecting 1500...

Looks fine to me. To be honest even if you’ve knocked into the top layer of fibre (and it looks like you’ve scratched into it) it won’t weaken it significantly enough to be a problem.

Sorry to be that guy but pretty much all the manufactures say you can't ride a carbon frame in a Turbo. It puts so much more stress on it than just riding.

Also probably shouldn't be doing sprint efforts on a turbo either
