Why? Do you think I'm trolling?
So why not simply make every frame use the same chainstay length? I'm sure they still contribute somewhat to the way a bike feels.
Is this a real question? Should every auto have the same wheelbase or width? We want our bikes to handle differently, given different functions.
Whether the triangle is smaller or not and the way that can contribute to a marginal increase in stiffness can be easily negated on a larger rear triangle depending on how its assembled and the material being used.
My frame apparently uses hi tensile for the fork and rear triangle. Presumably to offer some minor road surface compliance. Your bike uses HiTensile steel for the frame to meet a lowest price point.
Some modern bikes feature the seat stays mounted lower down on the seat tube than normal to offer a slight amount of compliance beneath the riders butt while stiffening the rear triangle a little like you said. Most modern builders have many, many models to suit different purposes. The lowered seatstay attachment on the seat tube is generally done for aerodynamic purposes after analysis in a wind tunnel.
Looks like GT realized with their modern implementation of the rear triangle design that the extra set of welds at the seat tube isn't an ideal place to incorporate stiffness. The GT Grade carbon frame actually has about 2cm of flex in the seat stays depending on rider weight and how hard you're pushing the thing. Smart design. I highly doubt seatstays flex 2cm on any road bike. Have never ridden the 'triple triangle' designed bikes.
Even with an ultra thin rear tire on my road bike (1.25") the amount of comfort and compliance I'm getting through the frame is remarkable. Even over major bumps the edge of the roughness is dispatched well. No need for wide tires with floppy sidewalls here, even if they did fit. 32mm tires are considered by many road cyclists to be unnecessarily wide and heavy. 'Floppy' sidewalls would be a sign of underinflation. Supple sidewalls in a quality 23/25/28mm tire are considered a positive, if inflated to an adequate pressure.
Would be nice to see that interesting seat tube design implemented more often. Check out time trial bikes from most companies producing race level frames, many have a curved seattube. I wonder why it isn't. Looks like it biases the weight towards the rear of the bike nicely . A well balanced bike handles better than a time trial bike

Short wheelbase is not a new concept, and the builder does not have to bend a tube to implement the concept.

Try reading up on a review for the GT Grade carbon. They mention it.
my Norco Monterey is a chromoly frame. Only the fork and rear triangle is made from hi tensile like I said. Im not sure how they managed to weld two types of steel together..
Ultimately there so many different factors which chsnge the way a bike feels such as the ATC length of a fork etc that its a wonder how some of us are able to make an informed purchase decision on a bike which genuinely suits our needs and riding styles
(You may think the bike you have suits your needs properly, until you try a different bike)
As for "floppy sidewalls" I meant tires that are around 2 inches wide or wider. You're not going to get that sort of sensation with a narrower road tire, obviously.

TIG welding.
N+1 is the only true path to cycling enlightenment.
After a few dozen bikes over the same number of years, most of us know what works for us.
Nobody knows what works for you, but you.
Ride On.
and, one should not believe everything one thinks -

Then they take a hiten tube, clean it, add flux, and braze it to the same lug.
And there you go- thats how they managed to 'weld' two types of steel together on your bike.

Your Norco obviously being a match made in heaven, a needle in a haystack. You are very fortunate to have found it!

it is a beautiful bike and probably comfortable enough for long saddle time . It just looks like it would feel heavy, particularly with that much water on board.

Great scenery, I was there July 21, 2018 on my 120 lb Rohloff14 tour custom. That was a long steady climb, and then all of a sudden I was at the top. I was expecting more climb at the top. Must have been way back in 1994 the last time I drove thru, after Portland.

It's still 30 lbs less than what I ride with IGH. And I'm 5'8". LOL
I take 4 580ml bottles on every highway ride 80 miles+.
I also have a tool thermos under my BB. It's like a 6 lb ballast tank. LOL. It works beyond my wildest dreams. I barely notice a 35 mph cross wind, even with a 14" nose trunk and frame bag.

he said”solid feeling bike without feeling heavy at all”. That was my reason for my observation. I am not a “weight weenie”. I just commented on a bike that looks like it would feel heavy. I also said what I thought, “it is a beautiful bike”. We ride what we like and I have no problem with that.

Awesome ride. Don't let these weight weenie nuts diss such an all round useful bike. But it does look like the TT is way too short for comfort bars.

Jake's a 60, seemingly small for me, but with a higher bottom bracket, fits perfectly.
LHT is a 62cm
Trek 1200 SL, 63cm
Bridgestone 200, I think it's a 63cm, too.
...among others.
