I found some very good advice on this thread. Thank you. I'm going to purchase a real TT frame this off-season and will be investing in a TT bike fit when that happens.
In the meantime I've got a short 12k TT coming up on Wed. and would appreciate and advice on my setup. Thanks in advance
Just want to share my wheel cover experience. Did two TTs on the same course two weeks apart. Almost identical weather conditions, pretty much the same power output and same time. First TT was done on 45mm carbon clinchers, the second TT was done on same wheelset with a rear wheel disc covers from Wheelbuilder. To my disappointment the disc cover made no difference over 20K TT.
Just saying ....

"I get paid to make other people suffer on my wheel, how good is that?!" - JV
On a 20k TT the expected performance gain of a disc wheel versus a 45mm carbon wheel is, let's say, between 10 and 30 seconds.
You say the weather was "almost identical" and the power was "pretty much the same".
Slight differences in wind or power or power spread might have seriously in fluenced your time here, making the disc come out as having no gain.
You can't just compare one ride to another.
Do the same course at least 5 to 10 times both with and without the covers and then take the average difference ... even then there'll be quite a margin of error but at least a lot less
Took into account all the advice in this thread and aww yeah. Did a solo TT ride and it went MUCH better than the TTT I had 3 months ago. Felt comfortable, used up all the energy I had and was screaming through the 2nd uphill portion. Now for a real tri bike and wheels...
Swim! Bike! Run!
Just wondering who's doing TTs this season? I'm signed up to the second one at Fiesta Island and will likely get into the rest. GL
I'm still here ... training on my indoor bike mostly because of bad weather lately around here.
Upgraded my bike quite a bit since last year and just bought myself an edge 500 a few weeks ago, so now I will have HR and CAD to help me get the most out of my TT's ... still not as good as a power meter but it's a major improvement over just a little speedometer
First nice weather no work day of the year, I'll be doing some HR/CAD TT tests on a flat road next to a canal I recently discovered.
Good times comin' up
Good luck to all.
are time trials that are part of stage races eligible for upgrade points when going from CAT 2 to CAT 1?
Here are the (simple) details:
I've got a question regarding bar-end shifters. I've finally replaced my 15 year old road bike, and I'm planning on converting it to dedicated TT bike. The frame was always a little small for me, and I can get into a reasonably low position on it. Being cheap (hence the fifteen years), I'm planning on converting the drop bars to bull horns via a chop and flop, and continuing to use clip-on extensions. I would like to get bar-end shifters for the extensions. In googling around, I've found listings for a handful of shifters marketed as "TT" or aerobar bar end shifters, all of which seem surprisingly pricey. Is there any reason why any bar end shifter wouldn't work (setting aside Campy to Shimano compatibility issues)? Does it matter that it's going at the of an aerobar extension rather than at the bottom of the drops on a touring bike?
How fast do you all think (opinion) someone should be on a road bike before making the upgrade to a tt frame? Example - 20k time should be around xx:xx before they have reached limitations due to there kit.? Just curious. Thanks guys
Irrelevant. I think it depends on the individual, their goals, the type of races they want to do, and their expendable cash. If you never want to do a TT, then don't buy a TT bike. If you want to become a TT specialist, then get a TT bike.
Putting the Duh in Floriduh.
Well I'm interested in tt and iv did a tri recently and quite enjoyed it. (punishable by death I know). A Time trial bike seems like an investment I'll eventually make but I don't know how long it'll be
Then again ... having done a few TT's myself ... I know that riding a TT with gear that is not near perfect will always give you an excuse to be slow.
Personally ... I ride to compete against myself primarily, but I also like to look at my results relative to others' to be able to put them in some perspective.
The thing is ... if you ride inferior gear compared to other people in the same race ... you'll be able to fool yourself by telling yourself that "they are faster because they have better gear".
It is only when you have a near perfect TT machine that you can really ride "the race of truth" ... a race where you can not lie to yourself anymore and where you are naked in the sense that your achievement relies only on yourself and your abilities.
I bought mine piece by piece and waited for the right bargins. Second hand for the frameset & wheels and in clearance sale new for the drivetrain.
I was able to assemble a full carbon, ultegra & dura ace, rear disc & 404 front bike for under 1500€, which I find very reasonable.
A good TT frame, at 30mph, might save you up to 10w or so depending on yaw angle. The biggest benefit to TT specific geometry is position flexibility. That said there's a lot more to sort out than the frame.
