Do you know where can I buy an 42 offset chainring for TSDZ2?
Thanks
This is the only one that I have seen: https://www.electrifybike.com/store/p65/42_Tooth_Narrow%2FWide_CNC_7075_T6_Chainring_%2810mm_offset%29_for_TSDZ2.html
I was unhappy with the chainline and used a made for Bafang offset chainring and drilled holes in the TS adapter, mounted it with spacers and a little longer M5's. I forget what those actually measurements are but can check tomorrow. It cost way less than the above and serves the same purpose as now the chainring sits about as close to the chain stay as possible giving the best possible chainline, especially in the lowest cog on the cassette, I use a 10spd 11/42. I figure that the chain is stressed the most while in that gear as when I am in it I am climbing something stupid steep and nothing kills chains faster than side loading them any more than necessary.
This Luna ring is along the same lines as mine: https://lunacycle.com/parts/bafang-parts/bbshd-parts/bbshd-aluminum-chainring-adapter-and-42t-sprocket/
It is 9mm offset and half the price of the first one mentioned, it would just take a little work to adapt. A word of caution though that going too far you will hit the plastic cover below the reduction housing and need to back off a bit.
