I went to my local LBS Friday to look at the Trek Shift 2 and also looked at a Shift 3 when I was there. The Shift 3 has a lot of features I like so I would probably be willing to get it over the Shift 2. Except - what concerns me is the Shimano EF65, 8 speed Trigger Shifters on the Shift 3. I am used to twist shifters. I would like comments from bikers who have used both. Are the trigger shifters OK? Hard to get used to? I am also trying to look at the Giant Sedona DX but the local store does not have one. Closest store with one is about 20 miles. The Trek LBS is about about 1 mile from me.
There used to be a battle for shifter supremacy between triggers and gripshift, but that war has ended. Triggers won the lion's share of the shifter market for mtbs, hybrids, derailer-cruisers, and other bikes with upright bars. Gripshift still has some die-hard fans, and I still like gripshift (although I don't run any currently....I'm more of a thumbie guy), but triggers dominate the market. Does that mean they're "better" than Gripshift? Not really; that's all subjective. But, it is evidence that triggers are at least "ok".
the only comment i can put is from experience from selling both... people who tend to only use twist grip shifters and attempt to try and use the trigger shifters they love them and wont go back. there is no fumbling around and twisting the bike. no taking your hands off the handlebars and no taking your focus off of the road. im always selling up to the trigger shifters not for the wrong reason at all for more money but just for a better value and also for safety concerns also
