SRAM X.O Twist Shifters

[TitusTi]

Grip shifters rock hard. I always used to like the idea of triggers' date=' but once you use grippers you find out just how fast they are to make a shift (especially when paired with an XO rear derailleur). Sure you will get 'grip shift thumb' at least initially, but the bugger toughens up pretty quick. Some okes whine about sore thumbs from triggers on the longer rides (Epic, for example) so I reckon it is six of the one half a dozen of the other where that's concerned. [/quote']

 

Not talking about short rides like the Epic, I'm talking about 24 hour races

GoLefty' date=' what is the weight difference between an XTR (new) dual control setup and a SRAM grip shift setup? Obviously it depends on the brakes you use for the SRAM setup, but is it significant?[/quote']

 

thats difficult to quantify because you have to decide on the brakes.

But lets say the set up is SRAM gripshift for Shimano with XTR BR-M975 brakes system, vs BS-M975 with shifters.

the only difference would be the weight of the gubbin on the bars. If I recall it works out to a polony skin under 100gr.

 

If you use Juicy Ultimats, Hope Mono Mini Pro, or the soon to arrive Formula R1, then the weight difference jumps to nearly 300gr!

 

gripshift gives you much more flexibility for a light build. They are about 90gr lighter than the triggers

They're nice but I find they rip my hands on really long rides (over 8 hours).

 

8 hours - thats about an average month for me.

My problem was a torn ligament in the thumb (gatekeepers thumb). I still get pain after 6+ hours but at least it is not 2 hours and I can move it. I think Sram twists might also pose a problem.

[GoLefty!!]

I think all shifters will pose a problem for you Dirtbreath.

the issue with any bicycle is that you require your thumbs to be wrapped around the bar to keep your palm in place. This supports your weight and provides the control, your palm, not the thumb. thats why you can get away with using a thumb shifter...

 

With Dual Control your thumb remains stationary allowing a position of control at all times. No matter what manoevre. I have never seen a rider change gears while doing a front wheel wheelie, I have seen a Polar Bear ride a bicycle though.

 

With Gripshift your thumb is again in the correct postion to allow absolute control. You cannot steer with your thumbs pushing levers and stuff.

 

Rapid Fire triggers are next best because the thumb doe not have to stretch too far  to work the thumb paddle. the release is effected by the index finger.

 

Impulse shifters on the other use only the thumb to effect shifting. this places more stress on the palm of the hand. I have found that I have suffered the worst hand pain using these shifters. Fuctionally they are superb though. ergonomics are a nightmare though.

 

 

Horse for courses though and personal choice and all that. I've used all 4 systems and I know Ilike Dual Control and Gripshift.Either is lekker

Try flappy paddle hand from the Dual Control levers during a 24 hour race. Triggers are much better

I've seen him do it! More entertaining than a polar bear.

I was going to take that as a compliment

but now I'm not so sure

 

 

 

 

 

[TitusTi]

Does anyone have pic's of that polar bear?

[Dirtbreath]

Lefty, the pain comes in the actual movement. Not once off but after a while.

 

I cant say if I would have problems with grip shift but I would think you need to grip and twist.

 

Funny thing was I didnt buy the DC's for this but did myself in on my first race on them. Was going round some walkers who were walking single track. Judging by what is happening with the teeter totter I should have sued.

 

Apologies for the hijack.

Seriously though, I find with GS my hands have to be off the shifter to be comfortable. Moving them on and off the whole time to shift is a hassle and as you might guess, it's impossible to shift when my hands are where they need to be for me to be comfortable and in control of the bike. If I keep them on the shifter I inevitable twist them unintentionally when trying to manuever the bike. Again....that's just me.

 

As for the thumb staying in position when using DC, I find that more of my grip comes from the forefingers in normal or technical riding and the thumb reaches far enough around the bar for my grip to be secure.

 

 

 

 

[GoLefty!!]

Ah you see it's personal choice Minty. Youhave a different wayof gripping the bars than I do even our hands both have 4 fingers and a thumb each.

 

thats why I say that for me I have found what is best..

 

not mocking you,...... well not really..........just lightheartedly mate 

 

I have seen a polar bear riding a bicycle at a circus in the Czech Rep.

I also have never seen a rider changing gears with a wheel in the air. Why would you want to, you're not pedalling.

 

but we each have different styles and therefore preferences. Anyone looking for advise on a forum would need to see if theres anyone with a similar style and see if what works for that person, will work for him or her.

thats what makes cycling great,.............shopping!!

I know....I never take you to seriously anyway...hehe

 

I haven't ever HAD to change gears while doing a nose wheelie. I have certainly done it though. Just trying to improve myself.
