GIANT AND LIV Launch together

Something must be wrong with those charts. Cannot be like for like.

With my X/Y then I had a choice of 3 Speed Concepts, and I’m fairly ‘short’ in body compared to my 1.92xm height. I’m 20cm reach too short on any of those and right at the bottom of the Y.

Someone has got the fit measurements into that table incorrectly as if it was that then you’d see it in the photos.

No, I take it back. I calibrated and measured the image at the top and assuming that the Liv bike on the left is a medium (matches wheelbase, calibrated to wheel circumference) then it is that short. In fact the one in the image has a couple of extra spacers to raise the pad 1cm over the min.

If you look at the bar design you can see the mono is only a little ahead of the steerer and the armrest mount is sitting back. So it makes sense that the furthest forward pad x is only just ahead of frame x.

Or at least, makes sense from the perspective of trying to verify their provided data. Doesn’t make sense from a fit range design perspective.

As for your earlier question - normally two weeks out on appointments.

Actually is that bridge mounted on the mono riser able to be flipped to provide more reach? It sort of looks like it’s possible in the pictures of the TT frameset. Honestly it wouldn’t be too difficult to make a new one with more forward sweep, similar to the mounting bridge made by FastTT. Giant could sell it for $200 and everyone would by it.

In fairness Trek do that with the 3 different mounts. But they are $400 (each side sold separately, and screws separately). So don’t count on what it would cost to make with what it would be sold for…

It is almost as high in pad stack as an xl canyon speedmax cf slx, just short in reach but that is a cockpit problem

Not enough stack for me. I just ask for 57-59 cm top tube stack and the option to mount a non-proprietary front end like TriRig. Doesn’t seem unreasonable but show me a top-end TT/Tri bike that has that now. I’m pretty much resigned to getting a p-series one day and spending the extra money on all the other stuff - it’s not a bad option, but I wish it wasn’t one of the only options. I won’t be replacing my rim brake XL Shiv (59 cm stack) anytime soon though.

The largest size on the new Ceepo Katana is 560y/460x with a standard steerer tube setup. That plus the Alpha One feels like the best option for tall people at the moment.

As Jeroen said if yoor t in a rush wait for his new frame.

Yup. Definitely intrigued by it. Unfortunately I may need something to get me through the first half of the year though.

Then wouldn’t it be cheaper to buy a longer stem and clip on aerobar til you find the perfect frame?

It’ll be interesting to read some real world impressions and measurements when the bike is out in the wild.

Just a basic question from someone who doesn’t have much experience with bike fitting.

I get the concerns around the limited stack / reach of the new Trinity per the charts but both are measured to the BB, right? But it looks like toptube length which measures closer to the saddle is actually longer for the new one (58cm vs 55cm for a large). So how does this affect the fit because we could design a bike with the saddle 2 meters behind the BB and still have the reach of the Giant Trinity if the BB to pad is the same (front section). Obviously this is theoretical but I am just trying to understand if the L is really that limited to tall people (>190 cm).

Mat, they have updated the diagrams and you were right it seems.

Hi all- just some info on the FastTT adapter following emailing them - the plate adds around 35mm extra reach

Thats hard to understand, as the extension mount holes on the FastTT baseplate are clearly forward of the mono riser, and the OEM plate has them set rearwards of it. The marketing spiel on their website also mentions extra reach. Im puzzled.

I dont like that di2 wires will have to run externally over the top of the base plate and into the central hole between the mono riser mounts An SD50 sized hole between the extension mounts, and a shallow cnc’d recess on the underside for the wire to sit in would have kept everything super tidy (like the OEM plate)



Correction after a few more emails- they had thought I was asking after the old Trinity adapter.

The new one adds around 35mm FWD reach

Have edited previous post to avoid confusing anyone in the future!

Does the FastTT adapter plate ONLY fit their extensions? Or can you simply replace the stock adapter and use the stock arm pads/extensions on top of the FastTT adapter plate?

Probably no reason you couldn’t do that. Tons of people use the FastTT adapter plates with TriRig Scoops Ultimate. The plates are really easy to add holes to so if the spacing wasn’t right it’s easy to fix.

Seems like a fairly inexpensive way to add some reach, and also gives you the option of running a bottle BTA as the FastTT mounting plate is pre-drilled.
