Yeah... started thinking "uh oh, where am I going to get replacement bits for my MTB?!"

You thought a link to wikichip was about cycling?

Age restricted and wants me to sign in :(

They're talking about the bicycle component vendor named SRAM:

It's been forever since I've been deep into biking so I'm afraid to click the link.

9 speed was already almost too much for a 'casual-enthusiast' [0].

But in general, Shimano or Campy is my preference for drivetrain [1] and Avid/Shimano for brakes [2].

[0] - I've blown out 9 speed cassette in less than 1k miles due to my riding style (skipping gears). NEVER had a similar problem on the 8 speed cassettes or 5 speed freewheels I would roll on.

[1] - Ok so I had a SRAM grip-shift break in a way it shot plastic in my face which was a terrible first impression. But also I've had 'issues' with a lot more SRAM vs Shimano when building/maintaining bikes. And then there was the Truvativ 3 speed road crank that could never get adjusted right (FWIW, I got the same 'model' as a double for a tandem and it was bliss... but that is my point about QC.) Also, that mess that was 'power spline'. Tore that up before in less than 500 miles.

[2] - In the day I was all about Speed-Dial 7s[3] for levers and BB7s for brakes (Very adjustable, none of the pains of fluid based disc brakes) and Shimano had a bad habit of trying to make things proprietary (center-lock disc hubs).

[3] - SD7s are the best retrofit-bike thing on the planet, because they can make all sorts of old/new brake combinations work with a consistent set of levers!

If it's been forever, SRAM might be worth reconsidering. Shimano and Campagnolo are both hundred-year-old companies, SRAM is much newer. SRAM is twice as big now as it was 10 years ago, they've improved by leaps and bounds compared to what you likely remember.

Simnplex forever!
