(Tried this in the unmoderated group, but it's not great for questions
in there!)

I gave into temptation last weekend and bought a run-out model Boardman
Team TT bike for my triathlons.

I've ridden it once, but didn't feel comfortable on it - since them I've
made some adjustments (moved the saddle back, flipped the stem and
adjusted the width of the aero extensions) and had a little ride up and
down the road - feels a lot more comfortable.

But... how long should it take to truly feel in control of one?

I have a sprint duathlon at Castle Combe racetrack next weekend - an
ideal place for my first race on it - but I'm really concerned I'll not
be confident enough to ride around other riders.

I could revert to my road bike - but this thing feels like it's worth a
good couple of minutes over the 10 mile bike segment.

As an update, I went down to Maindy track for an hour on Sunday to
fine-tune the riding position. Seem to be getting on with it a lot
better now, but not 100% confident in doing 10 miles on the aero bars.

I can't say I've ever ridden a TT bike but often a bike with different geometry can feel a bit weird but after a couple of hundred km or so feels absolutely normal. I would say getting a few more miles in on the thing is preferable to spending Christmas with some of your innocent fellow racers in A&E.

Anything from minutes up to never. Don't read too much into it feeling
faster, because twitchy vehicles (not just bicycles) usually feel faster
than stable ones, but may in fact be slower. Rely on timing.

You almost certainly have good balance and adequate reflexes, but they
won't be enough to compensate for an unfamiliar, twitchy bicycle. You
also need to train your reflexes, and that does not happen overnight;
it needs tens of hours on the bicycle.

Never used one, but those who do say you need to train to use it, if you do
they are fast! Blistering so.

Well, I'll give it a go this weekend, unless the weather is awful.

Castle Combe, as a car racing circuit, is very wide and has no really
tricky bends, aside from the u-turn into the pit lane for transition.

So it's a very low risk first race.

One thing I did note after last week's session on the track is that it
really works the core muscles.

Missed out on a course best due to completely cocking up T2 - I lost my
position in the racking and spent at least a minute looking up and down
before I found it. Argh!

Anyway, as I guessed, I gained around 2 minutes on the 10 mile cycle
stage. Struggled to spend a lot of time down on the aeros, but it was
rapid when I did. I think I need a bike fit - but first I'll get and
adjustable stem so I can fiddle with the aero bar height, meaning I can
spend more time tucked down.

Very happy with it.

(The downside being that you use muscles you don't use on a traditional
road bike, so the first 500m or so of the 2nd run was painful)
