What is the exact model number of this Tiagra?

[screels]

I need to order parts, but unsure of exact model?

Looks like a TI-30 (not a TI-30A)

From that one photo I would struggle to say. Do you have the right sideplate? Photo of the handle might tell all.

Interesting - I've not seen a Tiagra 30 before; 30W and 30WLRS, 50, 50W and 50WLRS but not the plain 30. Nice.

fwiw I think many parts for the 30 ought to be interchangeable with the 30W in the same way as the 50 and 50W - spools, shafts, frame etc notwithstanding.
