New Giant TCR Advanced announced

[neomoz]

Yeah, those Course 1 are quite heavy. Those tyres account for almost all the weight difference between the TRC Adv Pro 0 and Pro 1/Pro Team (about 200g).

Some good news : looks like a new Conti Grand Prix model is just around the corner and it supports hookless tyres! The max pressure for hookless is 73PSI, so it should in theory be compatible with SLR-1 wheels of the new TCR.

(The tyre is also being discussed in the "Everything Wheels" section of this forum.)

Yes I just saw these tyres pop up in my youtube feed, very curious on SLR-1 compatibility. I'm assuming the 28mm ones will work around 70-75psi just fine. I would assume conti worked with Giant on these news tyres to ensure the bead doesn't stretch like the older ones did.

Peak torque posted a video on the recent issue I had with the garmin mount. I felt it was a safety issue and it was a noticable improvement in handlebar stiffness with the mount removed.

He actually had the handlebars slip on him though. It's a bit of a worry, safety risk is real imo.

Thanks so much. Did they say anything about the price?

In comes out to a little under US$500

Looks like Peak Torque, Youtube or Giant took down that video. I watched it before it was taken down and was a bit worried to be honest since I am using that same mount. I just saw your posts regarding the two rubber rings behind the stem. I actually still had those mounted on my bike and I just took them off as a precaution. I've been using the mount on my Kalloy Uno for several months now and never had any creaking or bars slipping, but it makes sense that they should not be installed. I wonder if Peak Torque had the rubber rings installed on his bike.

If you get an assembled bike those O rings will be installed. Or at least they were on my bike. No slippage tho.

Giants' bars have short reach. If he's using something with longer reach (looks like he's big/heavy) torque might be just enough to have them slip under right circumstances.

Many years ago I tried a cheapo ebay sourced out front Garmin mount that came with plastic spacers to sit between the stem face plate and the mounting screw heads. The plastic spacers failed very quickly and visibily when 5-6nm of torque was applied to the screws to secure the Garmin mount to the face plate. I didn't even ride the bike.

I changed the plastic spacers for steel and no problems since.

Do yeah, I can believe an all plastic Garmin mount could have similar issues, unless it's very tough and/or selectively reinforced with metal.

The first thing I notice is an XS (so 6 frame sizes instead of 5!!). The S seems to be slightly bigger than the current S, while the XS seemingly takes the spot for riders @ 165, maybe to 170/172 instead of 175?

Sizes has been changed so much over the years..

Maybe Peak Torque left the o'rings on there also, or undertorqued the assembly (pun intended) , i would imagine that if his perspective/video showed zero faults from his part, the video would still be online...

And the spacers/bolt sleeves on the Giant computer mount are made out of metal, as are the bonded inserts on the base of the mount... when mounted correctly there is no non-metallic material between the bolt head and the stem face plate to compress and give way to slippage.

Anyone know where I could get the new seatpost clamp (the 4.5 Nm one) other than directly from Giant? Anyone come across any online retailers?
My bike shop where I bought my TCR is unable to source one for me

The photos on both websites seem to be from the previous version, but the part number (150000102) looks like the correct one. I might be wrong, so it wouldn't hurt to give them a call, just to be sure...

It should be implied that they are compatible unless Giant specifically lists them as incompatible because these tyres have max 73psi for hookless wheels written on the sidewalls, and Giant's website states:

"Please note that if the maximum pressure indicated on the sidewall of a tire is below 72.5psi (5 bar), the tire is tubeless compatible, and is not indicated as being incompatible with hookless rims, it can be used with Giant hookless WheelSystems and does not have to appear on the chart below [...]"

I would be surprised if those rubber o-rings alone caused the sudden slippage. The recommended torque must have a safety margin included. So it's likely that he "undertorqued" his to begin with.

You're probably right that the video was wrong and Peak Torque took it down himself.

I confirmed that the spacer and the base of the mount which interfaces with the bolt/spacer are metal. I've been really happy with this mount so I'm glad I can continue to use it without worrying about safety.

Indeed, great piece of kit, even adjustable in depth to match bigger or smaller computers. And weights very little, could be made even lighter if you changed the OEM bolts to titanium and the metal plate on the underside to a carbon one.

Only downside i can see is that it doesn't fit my Canyon's V13 stem, and therefore probably a couple of other stems where the bottom faceplate bolts are very far apart... measure twice, buy once.

Did you guys read the article? Basically what I took out of it is that Continental is forced to accept hookless compatibility BUT ONLY up to 73PSI. Giant test is above 73 PSI I believe. Also, Continental says they did not confirm claims of any performance benefit from using hookless. PLUS it blew out of the rim when you pump them up to 100PSI.
I think Giant RIMS are a bit better cause they have narrower internal width vs ZIPP tested.
