PSA for seraph TT-X70 users, replace the rimband when running with TPU, otherwise your TPU tube may go poof on a sunny day, it's definitely not strong enough.

I have the same handlebar. I am surprised that this is a reliable & solid option without a 3rd screw. Is it truly solid?

Yeah it doesn't matter really.
It was even too sturdy, first the plastic garmin mount broke twice and my light flew to the ground. Then the aluminium itself broke and I had to replace it.

I am now running this one https://de.aliexpress.com/item/1005009241828752.html Plus a light with less weight: https://de.aliexpress.com/item/1005006587080852.html

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

PD; The Computer mount it's really really flimsy, if anyone knows how an alternative I'll be thankful

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
