FWIW…I have a disc brake TT bike, and I’ll bet $ you’re still faster than me on your rim brake TT bike. It’s a sexy rig…keep sending it!
Really?
So a wider fork and wider wheels aren’t more aero than a bike equipped with rim/caliper brakes, requiring a narrower fork, narrower rims, and narrower tires?
Huh…. this is an interesting take.
I think TT/tri bikes are about to go next Gen with the wide forks and seat stays. I was considering upgrading myself but it would make more sense to wait for another year or two - like the new BMC Speedmachine. Then you’ll have so much tire clearance you could get rid of your gravel bike 
I didn’t need to get a disc brake TT bike, but I got one anyway 
I love my disc brake roadie/gravel/mountain bikes, so I just received my pretty, new QR VPRi on Friday. Life is short, buy the damn bike 
You don’t need a disc TT bike
You don’t need the new bike. BUT if you want it, can afford it and will enjoy it - get it. I’d just suggesting waiting a short while as its the middle of winter and the boredom could be the reason for the want. (FYI - I’m doing the same thing with my boat. I don’t need a new one, but…..)
that’s TT specific so don’t get your hopes too high. There probably won’t be any consideration for Tri attachments and the frame reach will be UCI limited.
There is no convincing evidence of it so far. The width allows you to fit lower CRR tyres.
I put my $ into triple glazed Passiv Haus windows, which we’ll finally be installing this month.
I went to the dark side (disc brakes and electronic shifting) kicking and screaming
Wish I had done it Many many years earlier.
Both are simply amazing for me personally

Reminds me of the time where the day before Tremblant 70.3 I lost rear braking ability on my 2020 Speed Concept (the last caliper model year) while doing my shakeout ride.
I brought it to the mechanic an hour before check-in - he legit looks at me and says “how well do you know the course?”
I reply that I’ve done it several times in a race and more times than I can count in training.
With a wink he says “Ah, well… you should be fine”
(He ended up being able to fix it, but it was all for moot anyway since that was the year it was smoked out)
Heh, if we’re giving suggestions on bikes and stocks in the same thread, got any more advice?

You don’t need disc brakes on a TT bikes.
I have rim brakes on my TT and disc brakes on my roadie. I really like the disc brakes when riding in the rain and going downhill. Rain and hills are something I avoid on the TT😀

Dev,
We may disagree on this one.
Sometimes experiences are worth buying what you WANT. In the case of the Rayban’s vs Generics perhaps the Raybans may have been the extra bit of confidence needed to get that date or that job. Or in many cases skimping causes you to buy twice.
In your case your purchase is really a few bucks in the bank, not the bike or the experience of riding the new bike.
Besides we all know for a lot people the P3 is the fastest bike their engine can handle, and for 15 or so years it was the cool kids bike in transition.

That’s some good power for that climb in the end

Well I got TSMC 2006 right, 2012 faceook right, 2013 NVidia and AMD right, 2012 Intel wrong, 2015 Xylinx wrong, 2020 Carnival cruise dead wrong, 2013 Alibaba barely useful, 2024 Micron right, 2013 American Tower Corp right, 2021 BYD roughly wrong, 2023 EssilorLuxottica right, 2023 Tesla right, 2016 Nextera right if you bought back then and sold last week.
Sadly for me, some got sold a lot earlier than last week, some never panned out. One stock did sell last week after a 14 year wait. I think any of us can put in a list of things that have grown because largely the entire market has, but largely any gear we buy is an expense that won’t grow which was the point I was trying to make to the OP who has a really nice bike and a disc brake bike probably barely makes him faster.
But as @gymrat pointed out there is value into what makes one happy. If its better gear, then fill your boots.
I was on a ride last fall (4 hrs) and we stopped at a corner store and my friend had his $10,000 Canyon. He said, “maybe one of us should stay out here and guard the bikes”, I replied, “no one cares about our stupid tri bikes. They won’t even know where to put them on sale, let’s save time and go in together, buy our gatorade and coke and get outta here”
To me the extra 5 minutes waiting guarding bikes, was a waste of precious time out of my life (i’d rather spend it making another post on ST than guard bikes, or put in a stock trade) . He had to devote his time to guard his expensive gear. The irony is last spring I asked him to join me on a trip to Victoria 70.3. We had to commit just when tariffs were down and the market took a hit. Micron stock went to $60 and I bought and went to Victoria. My friend said he did not want to travel because his investments were down and he is a retiree. Well in December he sells his perfectly awesome $10,000 canyon that is 2 years old for $6000 and buys a latest one for $10,000. That’s his choice. I got to go race at Victoria 70.3 and that race cost me around $2500 all rolled up (airfare, airbnb, hotels, rental car). But roughly speaking he chose to spend on a bike upgrade, I spent on a race, we both pissed money away.
To me time, is my finite resource. I don’t want to have to work harder and spend time to service my material assets, I would rather have more free time not being stuck working having to serve material possessions. All my material shit my family will throw in the garbage when I die. What’s in my portfolio, I can build something really useful for my family, so while tri makes me happy, I choose most of my tri spend on experiences (races, training camps), not gear which is why I did not upgrade to a disc brake bike YET, but my Argon E-117 has arrived at the shop and it really goes against my mentality.
And the problem with my time is I only get 168 hrs per week. I can only work so hard if I want to do sport too. When I buy stocks in other companies, i have a world of workers working for me, to help generate revenue versus me working to generate revenue. Ideally all these other people in other companies work for us so we can go out and train and race !!!
Any case, just sharing philosophies on what to allocate finite cash to, if we want to race and have time to train, while we need to put in time to work.
It’s a relatively long response (as most of mine are) to a post about spending money on gear. Some will glaze over it, thinking this guy is a polluting a thread about gear with life capital allocation discussion, some will read it and say, “yeah, I’d rather buy EssilorLuxotica shares and be an owner in Oakley and Rayban than buying their stuff from here on end, I’ll let others buy and benefit from their spend”
The funny thing is when I get my Argon Disc Brake bike, I am just using it locally, and will keep my old P3 for travel events. In effect, I’ll be like my buddy worring about his Canyon being stolen, but I can throw my P3 into a soft shell case that I barely ever pay bike fees with, that fits into a sub compact rental car, and the bike bag can be stored under a bed in my AirbnB and hotel. My entire system is too convenient. So the new disc brake bike will be babied, because you know it’s this thing I have to worry about now!!!

Don’t do it, I did it but dont think I did a great deal about it
@devashish_paul well put..
Lucky me at as I am a very leggy 6’4” Super Bikes dont fit me….
But I did buy a 3rd pair of Skis today that I absolutley do not need.
Nope don’t need them all. Wanted them and it was the reward for a decent 2025 at work. And i am going some place where Wider is Better in 2 weeks.
To the OP. If you want a bike go get a new bike if it will make you happy and gets you out the door for training. Bonus points if you beat your buddy or win your Age Group. Disc or Not meh, unless you find yourself at the top of Snow Canyon in a hail storm. Then you will need those disc brakes. Make sure to get a matching kit and shoes while you are at it.
I have a disc tri bike and a rim-brake road bike. The thing is that most of my riding has a purpose and a plan. Because of kids, I don’t have much time for “just riding,” which points toward the tri bike and specificity. Because of that, I do pretty much all of my riding on the tri bike. I’ll even do social rides with my wife on it, just softpedeling in the TT-bars or getting a shoulder-workout by riding on the bullhorns. And i just like the disc brakes much more (and the bike overall is simply better).
So i guess you should just upgrade the one you want to ride more. And some of us just like riding the tri-bike
