I've gone from the hand-grip shifters of my Trek 730 (about a 1993 model) ... to the bar end shifters on my Saluki. It took a while getting used to the bar end shifters, but now I love them, especially when riding in the drops. The brake levers on the hood of the Saluki is convenient for me, at least when considering that ... when I anticipate the need for braking ... my hands would be on the hood.
Studying Shimano's Dura-Ace 7803 gruppo components, I'm left confused on the following points:
* Bar End shifters are available ... but I see no brake levers listed ... for either the DA 7800-Double or the DA 7803-Triple.
* STI Dual Control levers are available ... for both the DA 7800-Double and the DA 7803-Triple.
* If I were to read into the choice of components, I could be led to believe that Shimano is encouraging the use of STI Dual Control levers ... versus ... the use of bar end shifters and separate brake levers.
Some questions please:
1. Is there more potential for maintenance problems with STI Dual Control levers, considering it's a two-fer device (both a shifter and a braker)?
2. Why doesn't Shimano offer brake levers on their website, for those who would opt to use bar end shifters?
3. Based on the difference in shifting styles ... between the 7800 Double and the 7803 Triple ... would one type of shifter be preferred over the other for the 7800 ... and ... vice versa preferred for the 7803?
4. Which shifter do you prefer? It may help us to specify your crankset setup, to understand your preference.
