How much speed will I lose if…
the human is the draggiest part of the bike/human machine.
and in my head there’s a rule-of-thumb-that-might-well-be-crap that says at 20mph half your energy is just pushing the air out of the way.
so, i wouldn’t be surprised if wearing baggies, and riding in a fairly upright position*, slowed you down by an mph or 2…

I’m just looking for a few extra mph. See people talking of 17mph + average speeds and I’m only looking at 15 or so
Well, a lot more will depend on terrain, wind, road surface etc.
And if it makes you feel any better, my last tow (lycra clad) road rides only averaged 13.5mph.Posted 4 years agoNorthwindSubscriber

Why go for the less comfortable, less practical, flappy, sweaty option just because you are worried about what other people might think?
I can honestly say I find baggies no less comfortable, less sweaty, and more practical (pockets!) I guess it depends a bit on your baggies.Posted 4 years agoYakSubscriber
wobbliscott – if you were swimming to get some distance in/ go faster , improve fitness etc, then why would you wear draggy shorts? I would certainly wear trunks of some sort. Similar situation on a bike. For any kind of getting-the-miles in riding, whether xc or road, why not go for the comfy and faster option of some well fitting lycra?
Re- what other people think? -i’m comfy so who cares?
edit- this might possibly be an old giffers point of view given that I can’t see much wrong with socks and sandals nowadays….Posted 4 years ago
TBH, I’m not fit but I wear lycra on my road bike, it’s the appropriate clothing for the activity, lighter, better at wicking away sweat, a bit more aerodynamic if you like.
you are probably going to put in the same effort in Lycra or Baggies I’d have thought, if so you’ll get home quicker and be just as knackered if you wear the lycra, save the baggies for MTBing…Posted 4 years ago
‘d say about the same as riding on the hoods instead of the drops – about 1 mph, or 10-20 watts. You need a power meter for callibration – i’ll commute in my Humvees on the road bike (for research purposes only – and in the dark, obviously )
Agreed. Frontal area and all that, there is an appreciable difference that comes just from getting your head down in the wind Vs sitting up on the hoods/tops…
Similarly flappy clothing vs something a bit more “Fitted” will have an effect too.
To answer the OP’s original question, Yes getting lycra’d up, as well as using the drops as much as possible /comfortable could take your 15mph Avg up to ~16.5mph without too much bother, obviously to up that Average further you’ll need to ride more, and get fitter, but that will come…Posted 4 years agoThe Sanity AssassinSubscriber
Biggest difference I found was getting used to pushing a 53t ring as opposed to a 44t. Once I’d done a couple of months and built up my strength then the averages rose quite quickly.Posted 4 years ago
Full lycra is the way to go though, it’s the right tool for the job.
Thanks for all the replies and debate. I’ve only had the road bike a week and I’m still getting used to it. I use it for commuting and have been doing 100 miles a week for the last 18 months so my fitness isn’t too bad.
I hadn’t considered the effect of building the muscles with the bigger ring, nor the consequences of riding in a group. I’m trying to use the drops as often as possible, but hand ache is making change position frequently.
Will give it a couple of months as see how the speeds go.Posted 4 years agotonydMember
Baggies will slow you down IMO. I’ve got some nice slim fitting waterproof shorts that go over bibs and don’t flap, they’re great through the crappy weather but get a bit hot once it warms up so I wear just bibs and a jersey. I tried wearing a pair of MTB baggies one day last week and as well as being too warm they felt like sails!
I’m happy wearing just lycra if out on a training ride but commuting I’d rather put on a pair of thin shorts, as the receptionists at work can’t stop laughing at me. Still trying to find some suitable ones (looking at swrve at the moment).Posted 4 years agomonkeyfudgerMember
Strava reckons my commute is on average 1mpg slower in baggies on the road bike.
I’ve just started getting into the roadie more this year the advice about just keeping on pushing the speed/big gears is goods, it’ll come*.

hi-5 fellow low gear user!
It’s alright, the fassion for huge gears was an 80’s thing. People have been spinning at 95-100rpm in lower gears since then as it’s more efficent for most people.
I just prefer it as it means I never need to drop out of the big ring unless things get really deperate.Posted 4 years ago
