You use the liner to give you a channel for routing the cables, then remove it. When swapping cables, you run a length of cable liner over the old cable, then remove the old cable, leaving the liner in place - I usually tape the liner at the top end to make sure it doesn't accidentally fall out. Then feed the new cable through the liner, then remove the liner.

With new bikes, many come with a string already routed through the frame that you can either attach to a liner or to the cable.

is nice

I very much appreciate the front views. I like seeing closer to what the wind sees.

I'm going to copy your brake setup. Need to make it flexible as sometime - brakes are actually used.

Racer Ex 

I can brake as or more effectively with the levers set like this, and I get as good or better a grip on the horns. Try it out, get used to it, and you'll see.

TMonk

Do you brake with your thumbs?

spdntrxi

do you have the 2 button di2 on the aerobars ?.. I see XXX so figure thats bontrager so no di2 buttons , just wondering about the front chainrings

Duke of Kent

Those are PRO bars...

If there was a bar that was compatible with Di2, I'd expect a subsidiary of Shimano to make it.

I mean the brake levers.. which I see XXX.. which won't have the Di2 buttons unless RacerX rigged up something. I know PRO.. I use them too.

as for the aerobars I mean the Di2 buttons specifically... DA has two versions.. 1 button and 2 buttons.. probably re-programmed to control the FD as well ?

sorry should have been clearer

echappist

the first picture clearly shows it's the R-671 (two button per side) as opposed to the one-button per side shifter

jsk

I think the two-button versions are Ultegra? Looks like that's what he has in the picture. I like the one-button versions, less chance of a mistaken shift. I figure if I need to switch to the small ring to get up a hill during a time-trial, moving my hands to the horns for a bit isn't going to be an issue. On the other hand with FD shifting on the extension bars, you can go without the Di2 brake levers (I like being able to shift from the horns during starts and turnarounds, though).

spdntrxi

aw.. I see that now.. looking at it from my laptop is easier to see then my phone

Duke of Kent

Why would a brake lever have Di2 buttons?

Or, what do brake levers have to do with shifters?

echappist

some people "hack" Di2 and append the shifters onto 3rd party brake levers

spdntrxi

integration.

Duke of Kent

So, by tapping to shift, you might also be tapping your brakes?

That seems like a very strange way to set up a bike, but, what do I know.

jsk

Not unless your have severe coordination issues. The shift buttons and brake levers are separate, they're just part of a single unit:

Drop-handlebar road bikes are like that, what's so strange? For mechanical shifting on TT bikes, you have to choose between the extensions and horns, so extensions make more sense. But with Di2 you can have your cake and eat it, too.

Just glued up some new tubbies, ready race on sunday!

why is your seat so far forward

Yep, brake with the thumbs.

The "blue" bike above is a variant on the USE aerobar. Different brake lever set up:



I've used these in the past and know several other folks who use them. They are fast, but not a big fan. Brake levers have a shorter throw and no adjustment vs. the Bontragers (or Specialized Shiv) type levers, on some brake set ups this can be problematic. You end up with your palms on the bare carbon and in a pretty narrow position if you need to make evasive maneuvers. I had them on my pursuit bike for a bit, always a little sketchy trying to hang on for big groaning standing starts. But fast they are.

The shifters are Ultegra. I'll upgrade to the single button sometime in the next few weeks; I had these sitting around and needed to get the bike up and running for Chico.

On the brake lever shifters: I think they are a negative ROI. They are quite bulky, and not terribly aero, and sit out "full frontal". If you're thinking strictly competition, how many seconds might you save using them? How many watts will they cost vs. something cleaner?

For training they'd be convenient.

[QUOTE=spectastic;18578473]why is your seat so far forward[/QUOTE

I had some knee pain and this is where I ended up comfortable. Is there something In should do differently?

spectastic

which part of the knee? that does not look like a natural position to me. a lot of times, knee pain is caused by the cleat/pedal interface. I would start there, make sure the knees are tracking in straight lines perpendicular to the ground, and then mess with the saddle.

Sizzle82

Pain was on the lateral part of the knee. I have done some adjusting to my cleat/ pedal interface and the pain has subsided. Maybe I will try to put my seat back a little bit. I comefrom almost exclusively riding a tri bike (former triathlete) and just feel more comfortable a little more over the bottom bracket.
