I just built up a Tarmac with the new Sram Red component set and it's frequently dropping the chain to the inside of the crank.
I'm running a SRAM RED AXS Power Meter Crankset (2 x 12 Speed) (48/35T) and new RED 10-30 cassette.
Here's how I setup and dialed in the system:
- Set up front derailleur with dedicated (red) FD setup tool. Rear derailleur was in innermost gear for the setup procedure. Side note: After using the setup tool, on the biggest gears (48x10), the gap between chain and FD is around 4mm. Much bigger than the 0.5 - 1mm recommended for fine tuning. When I actually bring the gap down to around 1mm, the chain will not properly engage when shifting to the big ring and just skip around a bunch.
- Used Braze on support wedge and double checked perfect alignment with the FD setup tool.
- Dialed in low limit screw to leave 0.5mm gap between FD and chain in 35-30 gears
Despite following the directions as closely as I possible can the chain will frequently drop when shifting from big ring into small ring. I’m amazed this is still a problem on a $5000+ groupset.
What can I do here to keep the chain from dropping? Is this just an issue that I have to contend with?
