Hello, is it possible to mount ±25-30 Litres of bags on to TT bike?
Is there solution to mount ±9L bag :
On CURVED bar ?
Yes, here exist aero bags, but it is only 2.5L 
P.S. Already have Gravel bike + Tri bar (with ± 30L bags)
But want switch to TT (like Specialized Shiv or Orbea Ordu)
P.P.S. “problem” is front bag, all other bags seem to mount fine
Will be happy for any answers
Anybody ?
I’m not sure what is the advantage of a TT bike for bikepacking. You’d lose a lot of the aero benefit with all those bags, and it wouldn’t be nearly as comfortable or serviceable as a road or gravel bike.
I haven’t tried myself but I would imagine the issue you are seeing isn’t TT bikes per se. It’s just that a lot of newer TT bikes have aero base bars with non standard tubes.
If you got yourself an older style TT bike with standard alloy tubing, it shouldn’t be an issue. However, the handlebar might be slightly narrower than on a road bike and the bullhorns might not prevent the bag from tilting sideways.
I am interested in why you want to bikepack on your TT bike? Are you planning on riding to races or are you planning on racing bikepacking/ Audax events.
As far as finding a bag you may have to get creative and strap on a dry bag.
marciviappiani thanks for answer!
My opinion TT is comfortable for long distance everyday riding.
What about Andrew Slodkowski (He cycled around the world in 80 days on TT).
ThailandUltras thanks for interest.
Planning “around the world” on TT bike, agree strap on is solution.
Just curious is there good real life example of mounting 25-30L of bags on TT bike ?
This is gravel, but bags on them looks interest.
i think this would be fun! maybe the way to go is with a frame bag instead? that plus a large bento box and a large saddlebag should be good.
i guess it depends on how much ‘bikepacking’ you’re talking about. my wife and i have done some “credit card tours” where we have a large saddle bag with a single casual outfit, a riding outfit, and some toiletries. handlebar bag for wallets/phones, and i carry the spares, and that’s it. but that’s maybe just a few nights on nice european roads with short distances between villages.
Reach out to restrap.
They make a custom frame bag and you get a template to use to send to them.
Maybe they would custom make others once you tell them your purpose.
I have their bags on 2 bikes. Really like them.
biking to and from races with all my race gear in the bag, etc on TT bike was probably more painful that the race itself. do not recommend. unless its a roadie with aero bars, the aero bars not for speed benefit but rest benefit
I did the Transcontinental Race this year in 13 days and am an experienced long distance cyclist.
If you are planning on 25+L I would get a Tailfin or similar. You can get a large saddle mounted bag, but it will swing around a lot.
I use Apidura so you could go with this setup on a TT bike
Aero bar bag - 3L
Top tube bag - 2L
Frame bag - 4.5L
Saddle Bag - 17L
Food Pouch x2 - 2.4L (This is the most useful bag you can add)
Total - 28.9L
For TCR I went with far less than this
Personally I would not use a TT bike for bike packing, Sherman’s neck could become a big issue - yes riding on TT bars is pretty comfortable, but doing this day after day for 12+ hours puts a massive strain on your neck muscles. A road bike with a proper aerobar setup, with lots of risers under the bars would be far better.
The other issue on a TT bike will be frame geometry and compliance, part of the joy of bike packing is taking smaller roads, often these are in bad condition or even gravel, a TT bike will be twitchy and uncomfortable. I would tend to use GP5000 32mm tires, which probably won’t fit a TT bike.
Another vote for Tailfin bike accessories. I converted my first carbon fiber race bike (Scattante road bike with clip-on aerobars) to a cargo-carrying commuter bike using gear from Tailfin. They are built to go on carbon frames without drilling holes. I do have a Shiv, and I think that the rear pannier carrier would work for it, also the rear trunk. The nice thing about the Tailfin bags is they strap down very securely to the carbon fiber pannier frame, so you don’t get a lot of weight shifting or movement from the bags. Not sure about a bar bag that goes from horn to horn, but you might find something that straps on underneath the aerobars.
