SRAM AXS Transmission Not Making 1 Shift

Tech Tech Help

I have a 2024 Pivot Switchblade with GX AXS t-type. For some reason it started to not make the shift from gear 7 to 8. It will go into gear 8 if I overshift into 9 and then drop to 8.

This began after I removed the mech after a trip into the mountains. Shifting was fine during the trip, but I wanted to give it a good cleaning and put up for sale.

I have installed/hung t-type components on 4 different bikes, including this one when I built it. Confirmed setup key, cog and chain length. I am using a torque wrench for the RD mount bolt and thru axle. Also tried to microadjust.

Anyone experience this issue and find a solution?

Thanks!

I am wondering if you might have a bent derailleur cage.

Try a new chain. In my experience, sluggish shifting starts on Transmission due to lateral chain wear. This occurs well before lengthwise chain wear indicators shows it as worn.

just to check are you torquing the RD to 35nm? This requires a larger than normal torque wrench

Thanks all,

I rehung the RD again for the 5th time and it was then making the shift. I don’t think I did anything differently than before. I have beeen using large torque wrench set to 35Nm, and compared pulley cage to a brand new pulley cage. Not really sure what was going on.

Chain is also fairly new, and been waxed since day one earlier this year.
