Which groups right for you: SRAM / Shimano / Campagnolo
That's a hard one, if you want top of the line go SRAM RED, Record or Dura-Ace. Now which one, again that a hard one, both groups have there following.
Campagnolo: Think of Campy groups like a fine Italian sports car, it will hold its value and had a lot of cool factor in its day. Today Most everything comes from Asia. Many still like Campagnolo but few will disagree they have Struggled to keep up with Sarm and all innovations and many 1st , lklike true wireless shifting total reliability.
Shimano: Dura-ace , Ultegra & 105 groups have a strong following , great group long lasting like Sram , Sram seems to always have the lastest features and 1st and shimano aways follows . Both Shimano and Sram great groups I just give Sram the edge
Sram
Group I use
Your pick: RED, Force, Rival .
Red equal or slightly better than D/A . Sram has great USA customer support service right here in Indianapolis Indiana in the Zipp factory Yes Zipp and Sram are the same company , very innovative in design along with its very light weight design. If you do not do your home work and take a close look Sram it will be a mistake. Proven to be very durable AXS E-Tap . Smoothest shifting on the market .Great factory support.
Sram AXS / etap
Best group we have ever used or sold in 50 plus years of shop owner ship and cycling No wires it true wireless and seamless install works perfect.
Its the group on my personal bike , I think that says a lot from a shop owner and a rider that rides 5000 plus miles a year
In our 50 + years of experience here at our shop, you can expect roughly the following mileage on your Shimano & Campagnolo road groups before you need to start replacing primary parts. High stress areas such as brake pads ( pads pick up metal shaving and should be replaced yearly or 2-3 thousand miles to reduce rim ware), Chain should be replaces every 2-3 thousand miles depending on conditions to save Cassette & chain ring ware, headsets (if you don't own a chris king forever headset), shifter springs, cable, and bottom brackets will need to be replaced more frequently. Other group parts will need replacing less frequently. Please use the numbers as a rough guides. Our experienced bicycle mechanic or someone you can trust can evaluate your group parts much more accurately at tune up time.

Sram groups
Easily 30,000 miles plus
On a personal Note Red E-tap / AXS on my Road , gravel bikes and GX AXS on my crossl Bike. Looks like Sram Red Etap will be a easy 30,000 Plus mile group. I'll keep you posted as the miles build for myself and other rides. How many miles do you have on sram?
Like I said: "I personally use Sram" Many serious Riders use RED and Force it the best I have ever used .
