I guess it depends on what you mean by "confident enough to go full-gas." I had the bike all built up and ready to ride in July of 2017... I raced it in two TT's toward the end of the summer and was defintiely a little sketchy in the first one. Throughout the fall of 2017 I did a bunch of training rides on it.. maybe a total of 250 miles or so.. 10 rides, 25 or so miles for each. Then, in 2018, as I started building up my training for the race season and weather started getting nicer, I began using it for 1 or 2 training rides a week. I was also adding in steady core training... pushups and planks to get the back, chest, shoulders etc, used to holding that position. By the time race season kicked in, I felt fine and I was defintiely trying to go as fast as I could in every race, not really worried about the handling of the bike.... that being said, most of our TT's are fairly straight forward from a technical perspective for the course.. out and back, one-way and some circuit courses, but even those don't have any crazy technical turns. I felt ok on the bike all season, but it definitely doesn't handle the way a road bike does. Just like anything, the more time you spend the more comfortable you will get.

Sounds like you adapted to it pretty quickly actually :P

Hoping for the same!

I have never run anything but my reynolds aero 90 front and rear in races or training rides(Don't have a disc). Although it can be a bit tricky in severe crosswinds it have never got off the extensions because of wind during a race. Going faster actually helps your stability too i find.

Refining and practising the position to be comfortable is essential. I felt i was going to die for the first few rides, and not having the brakes at hand is disconcerting. You will get used to it. Core work is also great advice. Enjoy the learning experience.

Along with another TT build, which is still in progress, decided to try something not-so-popular around - Cube Aerium SLT. The frameset is totally cheap compared to all other superbikes out there - you get everything except saddle, cranks, shifting and wheels - it comes even with a preinstalled Di2 wire in the downtube :shock: The only minor complaints while building it are:

1) after you install the BB, if you want to change something with DI, you have to remove the BB first
2) to raise / lower extensions is a pain in the ass. Then again, they provide up to 15 degree angle right away, which is rare among fully integrated bikes.

My previous TT machine did not have any extension angle change possibilities, so at the moment I've got no idea where my position will end, so the current angle is set up to provide maximal mantis the bike allows.

This one has also front hydration and bento box - similar in appearance to Canyon CF SLX, probably manufactured by the same company - Profile Design, not shown in pics here, though.

Weight as pictured is right at 9.0kg

2 button on the bars is 9071 or 6871(ultegra) .. extensions you only need 1 button to control rear der..

all the new DA Stuff is 1 button.. I too prefer the older and use 9071.

you can go to shimano homepage and look up install directions... all the part numbers are there.

Cant help you with specific cable lengths, and also where you are planning to mount your A junction box, but this should be your first port of call:

What wind speed would you consider too blowy for an 80? Just picked up an 808 front, but won't be able to test it for a while. Used a 404 on the road bike in anything up to 19mph before (not that I'd advise it).

Was thinking the 808 could be for sub 10mph wind days.
It depends more on what you are using on the back; ie it should be a greater depth than the front.
Running a pair of similar height wheels can cause buffeting of the front more than the depth being the reason.

Also how your front wheel interacts with the fork and affects it stalling is a contributory factor,
Sorry JM, but your rear is of little consequence as your backside weighs it down. There's also no discernable stall affect due to fork and wheel combo, given the speeds we move at.

Shrike, best way to get more comfortable is to train on it. Especially on windy days. I remember taking my HED trispoke out on a 50km/k+ day to see how it handles. At full cross wind (heading south, wind from the west) it was pretty frightening :lol: but at least then I knew how bad it would have to be for me to not run it. And still got the experience of wrestling it home.
The more you train and race in windy conditions with deep wheels the more comfortable it becomes. I too used to have the issue with trucks. But now am locking in on the skis so just keep on pushing along as they pass.

Just bought myself a second-hand Focus Chrono Milram frameset. Setting it up with 1x10 mechanical and a hed three spoke and pro disk wheel. I am in a budget so it won't be light or on the level of the other bikes here. However I like it and it fits.

Focus Chrono in Milram colours will be great. From memory the frame was designed by Andreas Walser and similar to his frames.

What do people know about grip tape now being (apparently) banned by the UCI? I was forced to remove mine pre Nationals TT week before last. Obviously being in a skinsuit meant I did not have the rule book handy. However at no point did I read about grip tape now being illegal.

Thankfully had gloves, as both base bar and aero extensions were nice and smooth for my sweat to pour all over.
