Candodavid, it is AndyCs Curtis, maybe thats why its so heavy…prehaps the “T” stands for tons! So sliding dropouts are a more reliable solution then.
Am riding a DeKerf (R725) here, with all sorts of magical craftwork / metalwork going on. Certainly very comfortable.
Interesting to here some more on 953…
Thinking some more, its noticable that Indy Fab dont really emphasise which tubsets they use by (admitidly it is usually a mix of 853 & True Temper) but I have the impression they prefer to concentrate on other aspects of the design
