Bicycle Mechanics - dumping the twist grip shifters

if i were to change from twist grip style shifters that i currently have to the better(in my opinion) trigger style shifter, should i also upgrade the derailers as well in order to get the full benifit of better shifters. right now i have the SRAM mrx plus twist grips and would like something along the lines of shimano deore. my rear derailer as far as i can tell is a shimano acera 8 and the front is c101 triple if that helps any. i really dont like the twistys any help would be greatly appretiated.

the bike i riding is a giant cypress dx

Unless you just want to spend money, I'd keep the derailers myself. Have plans to do this to my wife's Specialized Crossroads in the future.

What I like about grip shifters is that you can change several gears in one snap. 2, 3, 4, 8, whatever you want. I wouldn't want to give that up. bk

MRX aren't bad in my opinion. You could try Deore shifters, though I'd go LX for a few $ more. Same performance as XT with a little added weight. If those don't solve your problems, the rear der may be the next thing to replace.

Now that I think of it though, maybe you should take the bike where you bought it and see if they can adjust the cables. That stuff should shift quite well as is. Cables could be loose.

I've got the attack grip shifters on a cypress SX along with a 105 derailleur. Perfect shifts every time and I've never adjusted the cable. Ever. Grip shifters work and they're lighter than triggers.

Remember to get 8s shifters if you want to keep the RD. Ho

Sometimes you can go overboard on upgrades for low end bikes. By the time you put on new cables, casings, shifters and derailleurs you spent more than the bike is worth. You might want to look at a newer bike equipped the way you want. Good luck

If it was my bike, I'd do it. I've never liked twist shifters either.

You'll get new cables and housings with the new shifters. That's a big plus. The derailleurs that you have now will work fine. Make sure that the shifters that you get match the number of reaar cogs. You'll also want to get new longer handgrips when you make the change.

This has much more to do with the initial setup than the equipment.

Probably true. But knowing that 105 derailleurs are basically perfect, that also means that my shifters are perfection. If my shifters are perfect, it's likely that the MRX ones are too. Most likely the same indexing mechanism inside. That was my stealth point.

its not that the twist grips dont work, i just dont like them. when im pedaling hard up hill or just trying to make it to work on time:p i have a tendancy to pull up causing the bike to shift. dontlike that much. i am looking into an other bike, the Gary Fisher Cobia 29er.nice bike

My feeling exactly! It's why they have both chocolate and vanilla. Life's too short to "make do" with something, like twist shifters, that you don't like for any reason what-so-ever, and that is so easy and economical to replace.

I've used both Gripshift and Rapidfire-type shifters alternatively for many years, our police "fleet" has both.
Can't say as I prefer either one except for the vastly-easier cable change with Rapidfire. But how often do you change cables?
I can see where in hard uphill work you might inadvertently grab a gear with gripshift....Maybe the bar-ends would be a better place to hold on?

The 8-speed Gripshifters on my regular police bike are about 11 years old-still positive and reliable.
