Hello,
Brand new user of the Neo 2t 2875 and with the exact same cassette can you confirm what you did as spacers to avoid doing anything stupid or to be obliged to modify my rear derailleur each time I take my bike off. ? Thanks in advance !
For now I put only the 1mm spacer provided by Tacx.
rem: the spacer provided by shimano seems not to be able to fit the neo 2t or maybe i did not do it properly …
Thanks for your Quick response !
After the cooking and diner let’s go to the basement 
Regards
sorry this is an old thread, i just got a neo 2t and cant get into the largerst cog on a 1 x11 sram apex , i can see alot of talk on a 1.85mm spacer but where does this go? appreciate any help.
Hi sorry took a while to reply. I bought a new 11-42 cassette identical to the one on my diverge. 1x11apex sram. When I got the neo 2T I just mounted the cassette without any spacers with the exception of the one on the one for the through axle. My gears indexed fine on the road but have had to use a whole load of adjustment to get anywhere nearthe largest cog when I use the trainer.
