A useful comment.

So, are they different or are they the same?

I have a sirris and i love it. Very comfortable. Has mounts for fenders and racks that are important for commuting. I have had no issues other than wearing out chains and tires. There are faster bikes for sure. and lighter bikes. But the sirrus feels good to me.

I live in Spain, unfortunately , here they dont let test rides, I know its sounds strange but.... The sirrus I posted is exactly the same here , like the wilier

Its not very rainy here. I will do 4-5 miles distances, also some longer rides when i get the chance. I guess my man doudt now is going to a Mtb componentry (sirrus) or race ( wilier) It this is actually of some importance

Shimano and SRAM have different levels of groups,but they don't exactly parallel each other. Shimano's Dura Ace is their top road level,Red is SRAM's. As to which is better,well that's hard to quantify. There are fans of each that will argue their fav is the best. X-7 is about the same level as 105,and about a step higher than Tiagra(yes X-7 is MTB,and 105/T are road,but that really doesn't matter),so technically the Sirrus has better parts,but really the difference in quality and weight is single digit percentiles and a few grams. For the average user,they're not going to see the difference in use,but I personally would give the nod to the X-7 group because I prefer the action of the shifters(as I stated before).

For flat bar bikes,I'll pick SRAM over anything because of the shifters. For drop bar bikes,I prefer the action of SRAM's DoubleTap over Shimano's STI,but Shimano's hoods are larger and I find them more comfortable than SRAM's,so when it comes to drop bars I'd choose the bike with the best features/lowest weight/coolest paint job/whatever as opposed to what the groupo is.

Just FYI,for chains I always go with SRAM over Shimano. Same quality for a lower price,no goofy single-use pins,handy master link,and the grease that comes on them is more durable and less messy than the oil than comes on Shimano chains.

On these two bikes,that difference is meaningless. Swap the big ring and cassette on either and they will have the exact same gearing. Brakes should be equal on the two,provided they are properly maintained and the wheels are kept true. They're both 10sp,so chain life and replacement cost are the same. The real differences are in the chassis. Just looking at the specs,the Weekend is the racier of the two,with a more aggressive riding position and probably a little quicker handling. The Sirrus is the more "practical" of the two,with more tire/fender clearance and glove-friendly shifters. Unfortunately,the only way to tell which is truly better for you would be for you to test ride them and see which just feels better. If you can't test ride them,I'd at least sit on them,and decide which feels better.

Any chance they'd let you test them indoors on a set of rollers?

Thanks do much to everybody for all this attention to my questions.

I think I will able to try a bit the sirrus indoors, nothing for the bassano. Another doubt is the crankset, tiagra 34-50 on the bassano, Unknown Sram 34-48 in the sirrus. Am i going to note more speed in the bassano by using the 50 over the 48? Itīs only a bit bigger

Two teeth on the front is nothing,just pedal harder.

Just one last question , when you talk about the road group shiftters being smoother.

I used to ride a Trek FX with a Deore group, the shifting was quick and responsive, thatīs good for the city. What do you mean by smooth? its like shiftting is going to take ages to shift, comparing to a MTB, but in a smooth way?

I don't think it's so much the responsiveness of the derailleurs/shifters, but how the spacing of the rear cassette between cogs is so much closer, which helps in maintaining a given cadence.

The rooms full of engineers in Osaka Japan have done their best to turn shifting a derailleur bike,
into a skill free task
to improve marketing riding to a wider customer base.. .

And adopted the planned obsolescence from the US auto Biz,

to sell "new and improved" every couple years..
