I am new here, new account anyway. Here is the deal;

Several weeks ago I was diagnosed with Osteoarthritis in my right thumb. I love riding my bike but shifting with the thumb shifters is dowright painfull after several hours on the bike or if I shift wrong or the thumb on that day is sore or a hundred other reasons. I really enjoy riding and want to continue but cant deal with the pain after words.

I have been looking at these as a solution, I think they will be easier on my thumb: http://www.performancebike.com/shop/Profile.cfm?SKU=25417&item=50-6938&slitrk=search&slisearch=true

But I also see these: http://www.performancebike.com/shop/Profile.cfm?SKU=24653&item=50-6939&slitrk=search&slisearch=true and am confused as what they mean by: RapidFire Plus with 2-way release function uses a thumb button to shift up or down, and an index-finger trigger to shift up or down.

Does anyone have these and or would the first link be a better choice or the second link?

Thanks in advance,

Scott

Well, if you had to choose between the two, the TWIST SHIFT is better. The Rapid Fire uses your thumb. Your other option are Dual Control Shifter-Brake Combos like THIS.

I like Dual Controls, you shift with the actual brake lever, down with the bottom of your fingers or up with the top. Of course, Twist Shift will cost you a bit less if that's a concern.

I bet Dual Control is what you're looking for. The brake and shifters are integrated meaning you brake and shift with the brake lever. Basically you upshift (harder gear) by pushing the lever down with the palm side of your fingers and downshift (easier gear) with the knuckle side of your fingers. You will want to get a Rapid Rise rear derailleur as well..

Here's what you'll need:

Sram twist shifters are really nice. I have them on my bike. But if you already have a shimano rear derailleur, you may want to stick with the dual control levers.

SRAM makes the Attack shifter which is a twisty and compatable with Shimano rear derailleurs. They also produce the MRX and Centra shifters which are also compatable with Shimano derailleurs.

Anything from SRAM with the SX or X designation in front of the model number is SRAM only and will not work with Shimano rear derailleurs.

The most common and easy to find Shimano compatable models are the MRX Comp series available for 5, 6, 7, and 8 speed drive trains, and the Attack shifters available for 8 and 9 speed systems.

The most economical route is going to be to go with a set of twist shifters. No other drive train components will require replacement. Just make sure you get the "complete shifter set" as the twist shifter does require shorter grips to keep things from gettting too spread out on the bar. A complete shifter set will include the shorter grips to go with them.

Good Dirt
