I bought a walmart rode bike the Denali. Alright before everyone jumps in on their criticizm of department store bikes over all it is not to bad for daily commuting. My biggest gripe is the breaks are horrible but i can live with them till i save for decent brakes. I never really liked "Grip Shift" typer shifters as i had them on a mountain bike my mother in law uses. they do not stay tuned for very long. on this rode bike they appear in an awkward place. i am so use to the old days of down tube shifters reaching up to shift seems to throw my rhythm off more that reaching down did. Does anyone have any suggestions as possible replacements for a different type. I have the 80s version of thumb paddle like indexed shifters on my old mountian bike and i like them and they work well. This bike is only 2 months old and had needs frequent adjustments that i understand are part of break in on any bike. The derailers so far shift very crisp so my chain jumping problem and shifting problems are believe are with the shifters them selves. I cant spend 100 on a pair of shifters but something 50-100 dollars i could do.
