Did you find a mount for your bike? I am in the same situation. This Computer Mount is close to unusable.

I'm probably gonna try this one with some shims/spacers: https://www.aliexpress.com/item/1005004414005702.html

I think I found a sturdier mount: see Attachments

Hi y'all.

I received my seraph TT-X42 mid October and have been using it as my fast commuter in rainy, cold fall/winter weather (~ -8 - 10°C) . So far I made about 500km.
After 250Km I did a ultrasonic deep clean and relube on the chain and checked for chain wear, it was comfortabely below 0.5%.

Yesterday I wanted to upgrade to a KMC X12 EPT chain, Hot-waxed with super secret. (I believe this one should give me better performance & durability in wet and cold weather than a lubed chain, EPT coating against rust) I cleaned my chainrings and put on the freshly waxed chain and did a test ride.

Low and behold. The stock chain is far above 1% stretch and 4-6th gears are completely worn. The new chain skips immediately. I had to revert back to the old chain, at least that one still works with the worn chainrings.

TLDR: Do not use the stock chain from the TT-X42. It's garbage and will eat your chainrings, fast.


BTW, for tires I am using the Pirelli Cinturato Velo TLR Refl V2 28mm. Those are tanks. A bit heavy, but comparably, still quiet fast. Very difficult to mount though. The stock ones gave me a flat after less than 250km
