Seven's Mobius SL 100 mm suspension frame

The Mobius 100 mm is a unapologetic XCO and cross-country race bike. It loves short bursts of all-out power that push it through technical terrain and launch it down tricky descents. This bike wants to go fast, with snappy suspension that rewards bike handling skills and courage. The light chassis gives the rider the ability to "body" the bike through corners. Short chainstays add traction and acceleration to the mix.

Why this parts kit?

If you're looking for an excellent balance of value, light weight, and race worthiness, you may have found the right bike. Some of the most common reasons riders choose SRAM GX include:

  • Lighter kit per dollar than most other options.
  • More progressive and cutting edge parts design. They innovated 1x mountain parts kits and wide gearing with the 50t cassette. SRAM 1x is still the best.
  • Simpler shifting mechanism means lighter and easier to service in many cases than some of the other popular options.
  • Cross compatible: It's easy to upgrade over time or buy less expensive replacement parts if you destroy stuff a lot.

What's a Seven Parts Kit?

Seven tends to keep the kits matching by brand. While this make the price a bit higher we find that you end up with a better performing bike that lasts longer and has a lower total cost of ownership. Even small details like cables and housing that are kit matching. This might sound trivial but over a few months of riding a high quality housing set will perform much better than cheap imitations that look almost identical.

If you want something you don't see here, contact us with the changes you'd like. We can probably accommodate.
