More comfortable base-bar / brakes for training-only tri bike.
Quote
|
Reply
It looks like I will keep my P2C and use it for training only. This is making me wonder about a more creative solution for a comfortable training-only tri bike:
- Install standard handle bars. This not only improves hood comfort but gives me brakes that actually work.
- Install DI2 so I can shift from both the bars as well as the hoods.
- But do this on my P2C (or maybe an older aluminum cervelo) that allows me to have seat and aero-bars identically matched to my race bike.
Has anyone ever created such a monstrosity?
The reason it's tempting is that I have to do a lot of riding on the hoods to get in and out of the city, on junky roads, in traffic, red lights, etc, before I get out to the open road and move to the aero position. The current hoods/brakes are uncomfortable and ineffective, and having to go to the bars to shift is annoying.
I doubt this will happen because I'm not sure I'm game to shell out for Di2, and if I did it seems odd to put it on my training bike rather than my race bike. But it actually seems to give me more value there than during a race.

personally I would skip the standard handle bars. just use a base bar with nicely up-angle extensions, and large brake levers.
this plus Di2 should get you what you want....with enough bar tape. saves a bunch of money not having to buy sti shifters.

Well I'd want the extensions to be identical to my race bike.
I guess I could just wrap the hell out of my base-bar, but I'm not sure that will approach the ecstasy of a nice fat recent-generation Shimano hood.

Sweet. I guess I can't patent the idea.
How are those extensions attached to the bars? Good ol' clip-on aero bars?

So assuming I want normal shimano hoods, what's the cheapest way to go about this?
1) An ultegra DI2 build kit like this: ($1,350)
http://www.competitivecyclist.com/...amp;PRODUCT.ID=10277
2) DA bar end shifters: ($279?!?!?)
http://www.amazon.com/...-speed/dp/B002SR7GJG
Will #2 plug into #1? #1 is designed to take multiple inputs?
3) Road bike bars (I already have these)
4) Clip on aero bars?
This is turning out to be awful pricy. Is there some cheaper way to do this, by hacking on my own buttons? From what I'm reading Ultegra DI2 is harder to hack.

Just throwing this out there, front shifter STI and the rear shifter on the aero extension and pass on the electric shift. I'm pretty sure if you spend the money to put Di on the trainer, it won't be long before you "need" on the P5. :)

It might look a little funny but I think that ship already sailed with the road bars on the P2 :)

I could do this for free too, because I have a road bar and pair of 6600 shifters. Hmmmmmm.

You would have half a dozen gears you could be in and shift the front derailleur to go up or down,,,, a big up or down and adjust as traffic, situation etc. allowed and have for the most part, normal shifting out of town in the aero position. It would be functional, with some small draw backs but the price sure would be right.

Wow, it's so horrible it's great!
I haven't changed the front shifter cable yet but that will have to wait until tomorrow. But even without doing that at least now I have decent brakes and more comfortable hoods.
The $25 adjustable stem that you'd expect to find on a rental bicycle really pulls the look together.

Hey you might look into the J-Tek Engineering double shift... It's a mechanical way to have both STI and bar end shifters, and it's only $50. On my road/Tri training bike, I have STIs on both front/rear derailleurs, but then have the double shift in the rear der as well so I can shift from aero position. Funky, but very functional.

NO FRIGGING WAY!
Precision is required for crisp rear shifting though. I wonder if this will make it craptastic. I'll give it a try though.
You and Cruise may have just saved me a lot of money!

It takes more fine tuning and has to be adjusted more frequently than if you just had a normal set-up, but if you get things dialed in the shifting (from either STI or bar end) can be perfect. If you get lazy and don't give it a quick tune up every 100-200 miles or so it can get "craptastic".

Sorry for the delay in responding... but after using it for half a season the verdict is clear: it sucks.
The shifting from the aerobars is fine, but shifting from the brifters is gushy and inconsistent. I have to continuously fiddle with the adjuster dial on the JTek in order to get brifter-shifting working smoothly, then put it back when I'm ready to switch to the aero bars. And even when it's working smoothy, shifts from the brifters are mushy and slow.
I spend a lot of time on this bike in the summers. I think I'm going to suck it up and go Ultegra Di2. :(
