My 30t arrived today, can see a few machining marks but generally looks good, and yes it is very thick but so is the 34t vectoix I already have.
I think the cheaper TT rings must all be cut out of the same chunky old plate and obviously as there are so many machining op’s to do on the tooth profiles to save time, cutter wear and hence cost they have to leave a fair old chunk of material behind at the base, RF and other more “Premium” brand rings will have more material taken away, making them lighter but obviously a bit pricey-er, you pays your money etc, etc… You could always take a drill to it if the weight bothers you that much, was only £20…
Although I notice the price has gone up by a fiver since I pre-ordered mine last week… Stealthy 😉
