double-indent bar with single cable(7 posts)

double-indent bar with single cableM3 Pete

my LBS put a Forma 2 handlebar on my bike, and I have Shimano 600 STI, that only routes one cable under the bar. The bar has two cable indentations, but the indent facing the rider has no cable in it. The result is a fairly sharp bend at the top of the indentation, exactly where my palm rests on the top of the bar. I've experienced some numbness in my hands. Would placing a piece of cable in the empty indentation help "round out" the bar and help my hand problem?

I have the same issue with my Cinelli bars; double groove, but only one internally routed cable. I have chosen the leave the flat surface on the bar where the second cable would be.

I would say there is nothing wrong with adding a second short length of cable under the bar tape to round it out. I don't know if this will solve your numbness problem though. What kind of bar tape are you using? Maybe switch to a more padded bar tape also.

Good luck.
I wouldn't run a there cable, myself, because then you would havebill

the opposite problem. Even with the indentation, the cable under the tape sticks out some (although it's not terrible and you certainly may like it better). But I'll bet that your LBS has lying around in their "everything" drawer pieces of foam rubber that often enough come with bars to fill the indentation not being used (it's a half-moon shape). If you can't get the foam supplied for the purpose, you could substitute something. Look around your basement.
BTW, it's really not a big deal either way and is mostly cosmetic. I doubt that it's causing your numbness. Loosen your grip. I'll bet that THAT'S what's causing the numbness.

i've had 2 of these bars -- i like them. TTT bars come with rubber inserts for the unused groove for the benefit of shimano users. your lbs probably didn't know what they were, was too lazy or proud to read the product documentation before they installed the bars, and threw them away. these pieces can be ordered separately from the bars. i'd mention this in a diplomatic way to your lbs. they should deal with it at no further cost to you.

I have the same issue cause I still run downtubes and the last set of Cinelli bars I ordered have those stupid Ergo grooves. I just put a piece of housing under there but it didn't really improve things. Looks lame, too.

Still, I doubt it's causing your numbness problem - I'd look at your fit and positioning. You gotta be relaxed on the bike - you should be putting little pressure on the bars. A good way of thinking about it is, if someone were to suddenly pull the bars away from you, would you fall forward? The answer should be no.
Use silicone sealant, not housingzelig1

I use STI and as single groove bars have disappeared, have used silicone sealant in the extra groove. Just lay a nice bead in the groove, taken a piece of cardboard with a semi-circular cutout about the width of the bar diameter and drag it along the bar to fill the grovve and take out the excess. Let it cure for a day. Probably doesn't weigh more than empty housing and is a lot more comfy. The stuff peels right out if you need to remove it but does come out when changing bar tape.

BTW, if you worry about the extra grams on that 199 bar, you shouldn't be reading this.

a filler that would allow use with a singe cable routing. They are black rubber strips. Ask your LBS for them. They should have installed them when installing the bars. Just lazy on their part.
