Thanks so much chewa.
"My prayers have been answered."
Since you are bound to know more about these than I, have a question have been wondering about for years. David built many frames with his signature "hatchet head" seatstay attachment yet yours has a "normal" seatstay treatment. Do you know if it depends upon the model or if it varied with time?
Thanks again for making this post.
