Here's what it looks like:
Now I want to buid a complete TT cockpit, with TT shifters and aero brakes. I'm already changing the extensions for some Profile Design ones, because they allow for a lower position.
Now for the basebar. There seems to be more and more even, flat bars, compared to a few years ago where basebars were lower at both ends.
What are the advantages of even bars ? Is it because the positions are so low now that one doesn't have to get lower to reach the brakes ? The ends are completely horizontal now instead of looking like the bullhorns, I guess for better aerodynamics ?
Best of both worlds is to get a flat base bar which allows the extensions/pads to be stacked higher, but practically this gets a bit dangerous over about 50mm rise due to flex in the system.
I understand the restrictions of bike numbers and cost, but is swapping out the whole front end and recabling really feasible for one or two TTs? Old P2/P3s are going pretty cheap these days 2nd hand. Might have some USE Tulas for sale soon if you are interested. (UK based though)
Off topic: I know the Aspide is marketed as a TT saddle but there are much comfier options around!
I'm thinking of eventually building a second bike out of a cheap TT frame ( with BB30 so I can swap the Powermeter ). But it's out of the question for the moment (read a few years here...). Since I have all the parts but the basebar, I just want to have the right part, with budget in mind.
Installing the whole cockpit would require less fiddling than adding the extensions (wich takes 5-10 minutes). A few cables, four screws to fix/unfix. The worst part is the rear brake cable but it's easy to run through the top tube. All others are outside de frame .
Cheapest now would be Deda crononero. Looking for something in the likes of the Zipp Vuka alumina too...
I fail to see how you can fit a new cockpit in less than 10 minutes? Even in a fully kitted workshop with all the tools and suchlike ready to go (and all new and shiny, no slightly used stuff) it takes me about 15-20 minutes just to set up all four cables properly.LouisN wrote:Installing the whole cockpit would require less fiddling than adding the extensions (wich takes 5-10 minutes).

You've got to think about re indexing front and rear gears, adjusting the headset (as you are unlikely to need the same length stem going from TT to road) and sorting the brake cables.
Not to mention the rate you'll go through cables, three or four cycles of removing and refitting inners tends to leave them looking a bit, um, cacky. You'll probably end up with problems there (spare strands getting jammed and so on).
I'd just stick with extensions until you've got the cash for a TT frame.
Or have a look at this. viewtopic.php?f=3&t=118073 which you actually posted on!
It's not like you need an expensive super aero frame, just one that gives you a good fit.
FWIW, I've got a set of USE Tula bars, too. Those are about the lowest stack bars you can get, with the pads at the same height as the base bar. A low stack means you don't have to drop your (adjustable) stem that much. Looks better, if anything, but also allows you to go lower. But I guess any alu base bar should do. Not all are UCI-legal, so if that matters for you; measure them first. Profile Design makes several, so you get a match with your extensions. I'd get some solid brake levers. I liked the Tula flight pods, but found them lacking braking power (even more so combined with Omega brakes). Luckily, USE also makes 'normal' straight brake extensions. I fitted these with Dura Ace TT brake levers, clear improvement in braking. In your case, the added advantage of having a setup that brakes well, is that you won't have to re-cable until the next road race. Brings up another thing; if you can check first, pick a base bar that makes cable routing easy.
edit: if you go to the thread Mattr linked to above, read cyclenutnz's post. Position is what it's about. Take your time to get dialled in on the road bike and either find the right position that you can then use to pick the right TT-bike/frame in the future, or find where the roadbike limits you and do the same. The only issue is that you'll have to ride the TT setup a lot more than twice a year. So once you make the setup change; train and test on it, the powermeter is your best friend.
I love you guys. Seriously.
I'm pretty happy with the actual TT setup. I won't be able to change things much without being illegal for saddle position. Maybe cut the saddle nose, ore use an Adamo type saddle can bring me forward a little, but then I'll have to rise the saddle, I'd have to buy a longer ISP topper, and probably longer adjustable stem...
My main concern: I'd like to be able to shift gears without having to move too much on the cockpit to reach for the right lever.
Our TT's are all on rolling terrain, so we change gears many, many times.
Maybe keep the road bars, just put the right TT shifter on the right extension and swap only the rear shifter cable/housing ?
What do you think ?
Easiest swap would be with electronic shifting, but thats a whole world of money extra!
Road bikes can be fast even without extensions! I've got a local course record on a Hilly tt, (read 5miles downhill u turn and come back up again! 70m climb) on my road bike with borrowed 808s, rather than my tt bike, as i felt able to attack the descent more and benefit from a kilo or so less to accelerate on the way back up. It probably helps my bars are 13cm below my saddle as is, so riding in the drops gives a pretty flat backed position.
@ graaf USE Tulas awesome, for both stack height and aero, but i find mine in 38cm width a bit more of a handful on technical courses, which are the majority of what i have to race on in my new area. Nokons made the braking much better with the Tulas.
I suppose the cervelo bar could look better if I just chopped the ends off too, as I think this is what was bothering me most...

Considering you're happy with the current TT setup, don't want to fork out a lot of cash and would want to keep the change easy, that sounds like an excellent idea. Also keeping the nature of your courses in mind.
I don't quite understand why getting an Adamo would require that much adjustment, unless you believe every cm more forward will require a move up (saddle) and forward (bars) as well. The Adamo's have about the same stack as your current saddle, and being _able_ to just move a little more forward, in comfort(!!) on its own can make quite a difference. If you need any adjusting, it'll likely be enough to move the extensions out a bit, that's easy.
I love you guys. Seriously.
