How to improve bike handling for TT riding

A light bike doesn't replace good fitness.

Hi -- Simple question. How do I improve my bike handling skills, particularly in aerobars for TT riding. Despite riding an Enve 5 front wheel (generally regarded as "tame" for it's depth in crosswinds) and a Disc in rear, I find I'm just very nervious riding in aero in 1) moderate+ cross winds and 2) a higher speeds, especailly in crosswinds. I've made some fit changes to my bike (widening pads, which has helped at expense of aero), but it's not enough. I'm consisently racing 10%+ below my power targets because I'm holding back due to fear of crashing and/or sitting up on the base bars.

One thing I considered was getting a mountain bike, and riding that all winter instead of spending it on the trainer.... but really, I'm at a loss....

I think you need to power through crosswind instead of holding back. Also, maybe stronger core muscles to allow more stability from saddle.

Could you post a side profile picture of your riding position please?

Is it simply because you're on a tt bike and the way it handles is very different than a regular road bike? and how long have you been riding the tt bike. My friend that is a good mtb'er also said tt bike handling in the aero position is really weird.

Agree to those above that say that it's just a TT thing. I've seen road bikes with clip-ons that handled kinda funny due to position, but it's pretty rare. TT bikes just feel different.

Slim posibility that you're running the front tyre too soft, but unlikely to be a real problem. The weight split is considerably different, but you'd have to be running super soft for this to be an issue.

So the answer is probably aclimatisation to develop confidence. Do more hours on the TT bike both on the turbo and on the road to get more comfort and confidence. On the turbo you'll just get more used to the position so it's less unfamiliar on the road. On the road you're actively practicing. Use shallow training wheels if you feel you need to in order to minimize the impact of cross winds.

Step 1: Shallow alloy wheels.

Step 2: Power thorough winds rather than backing off.

Step 3: Lots of hours. Image

Echoing what has been said- the specificity of TTing requires considerable time to develop comfort with all the things that come with TTing, in order to go full gas.

A couple other thoughts-
*Spend time riding with a rear disc to get familiar controlling it as a sail. A windy lonely country-side road may be a good place.
*Depending on your weight, position, etc, you *may* be better off with a mid section wheel on the front that you feel comfortable with. The idea here is to have the side windloads be +/- balanced front & back. Too deep and the front will be pushed harder than the rear. Too shallow, viceversa. Works for some, not all, and again, lots of hours.

Don't fight the bike to hold it straight when a gust hits - allow the wind to push you off line, just smooth out the path a bit and then ease it back again gradually.

I´d spend a lot more time on the TT bike. You don´t even need to get that much time in the aero bars. Do a lot of training in the bull horns. It's all about learning how the bike handles. TT bikes tend to handle slow since they are meant for riding at hight speed, where you don´t want fast and twitchy handling. It takes time to feel comfortable with that kind of handling. But do a lot of regular rides in the bullhorns in some semi technichal places, where you learn to feel confident in how the bike handles. I´m pretty sure this will give you more confidense when you´re riding in the aero bars as well, since it´s all about feeling confidence in the bike in general.

That said, a larger size of balls are needed riding fast without being able to reach for the brakes. That´s just part of TT´ing.

If you look at kona, most of the tri riders do not have discs. It is a course known for wind btw.

I say drop the rear disc for now, and train with something in the 50-60 range.

I am new to it also, but my bike came with reynolds 58/62’s so i think it is a good starter set. I live in an area with wind most of the time. I will try a rear disc, but onlt when i am more comfortable: just temember that in some conditions, very few to none of the pros ride discs/really deep rims.

Pros (and amateurs) do not get a choice at Kona. Discs are NOT allowed at the IM world champs. :smartass:

I'm not criticizing your choice of wheels or approach, but if one wants to go full-gas at proper TTs, one needs to train w a disc in order to maximize speed.

Its fine, 56/42 osymetric makes chain sizing a bit more snug than usual. Still plenty of swing left in the mech and is never ridden with that much cross on the chain as it rubs pretty horribly on the last 3 sprockets. I was just lazy that day as I rolled into the Carpark and crossed it knowing I'd swap it to the Little ring before it went into the car.
