how steep can you climb?

rek

Just a little curious...<br /><br />How steep a gradient can you people ride on your bike before you start to scream in utter pain and curl up into a fetal position etc.?<br /><br />In my lowest gear (39x25), anything more than about 7-7.5% is enough to make me think walking up is a really good idea..<br /><br />Whenever going up a not-short climb (like 500m+), my HR usually shoots up to about 85-90% max .. does this sound a little high to anyone? Should I turn the wick down a bit on ascents? I figure hills are going to be a hard time, so I may as well get them over and done with quickly.<br /><br />I'm still somewhat heavy for my height (91kg, 183cm) so I still have a few kilos to lose ... how much easier would it be if I weighed, say, 5-8 kilos less?<br /><br />I normally try to keep control of my breathing (make sure I take deep breaths) and maintain a cadence of 90-100rpm wherever possible (I heard Lance climbed at high cadence on the TdF coverage commentary, so it sounded like a good thing for me to do too .. )<br />

There is a 2km climb i got up once or twice a week, its ave gradient is about 12-13 %. I've only got a 39x23 so its a bit a churn to get up it ;D

Duckwah

I've got a 30x25 and i can climb all day :P<br /><br />But its very slow :'(

Is this where I mention my 30x26 granny ring, or would that embarrass me? Ahh well, what the heck, don't think there is a climb on the road that would be too steep, just too long. Only onw climb has made me get into that granny gear on the road, some insane thing in the middle of the Tour De Gold, don't have a clue on the gradient but I was the only person cycling it amongst the people I was with....<br /><br />On a MTB its really more a case of traction than steepness. I've gone up some pretty serious gradients where they've put down some concrete to let the poor little cars make it up. One little climb always got me, you had to keep your pedal stroke exactly the same, your weight distribution just right and pick the right line or you would lose traction, best I ever did was probably 3/4 of the way up this thing (1.5 km climb, no idea of gradient, but I've never seen anything like it on a tar road). Now that is with a 22x32, a bit of overkill, anything you can't push a 24x30 on is going to be too steep to get any traction on...

Did my first ever &amp;quot;serious&amp;quot; climbing effort yesterday!! 13km of mountain-ish ascent (for the Melbourne people, Montrose to Olinda via the Mount Dandenong Tourist Road) .. a bit of 5% to start things off, 7km of constant 4.5% climbing, followed by 3.3km of light hills, finished off with 1km or so of 6% to get to the summit.<br /><br />Not exactly Ventoux, but that final kilometre really took everything I had .. :-/<br /><br />Coming back down was such a rush though (ave speed 54kph) ;D Made the pain all worthwhile.

Jeez, looks good. 13km is a long time to be going uphill

Where I live there are no hills. the nearest is at 40 km from where I live but it's a hard one. It's de kemmelberg, you furst have the 'monteberg' wich is about 4-5% and 1 km long, when you are up, you can go left on the kemmelberg (maybe you know it from 'gent-Wevelgem') that is 800 meters at 20 % on 'kasseistenen' that is really hard.<br /><br />You also have the 'rode berg' wich is alo 20% but only 300m and on normal road<br />

Very many years ago when I was in the UK, hills were marked as ratios. We used to go around looking for 1:4s to test out on. :P What does that translate to in %? Are they still marked like that in the UK? There was a famous one in Devon somewhere reputed to be 1:3.5 but I never got there. (I couldn't even WALK these today! :'()

1 in 4 is 25%. Either way, you won't catch me even trying to ride them! I'll drive the Directeur Sportif car up them if you like ... :P

Old Timer over here in the UK hills are now marked as %, though it only been for the last couple of years.<br /><br />There's a hill near me that despite the fact that it's short is a real killer (i swear it's vertical) but I don't know the gradient , I failed the last time and that was on a Mtb, since then I've bought the road bike and I think my leg strength has improved, maybe I'll give it a go this week :-\

I climbed a set of hills near Avoca Beach (New South Wales) I like to call The Despicables. Short (500m), but cruelly steep. On the nastiest of these, as I climbed I could hear nothing but the gasping of air ond the screaming of muscle.<br />Imagine my surprise when I topped the hill to find two kids (read 10yo) rolling behind me on dragsters.<br />I ask them 'Did you boys climb that hill behind me ?'<br />'No' they reply 'we heard you coming up the hill.'<br />'Can you guys ride up this hill ?' I demand<br />'NO' the giggle in reply 'we've never seen anybody TRY to ride up this hill before.'<br /><br />That was on a MTB, no chance on my roadie.

Rodeberg is only max 16% on normal roads<br /><br />Buth the real killers here in belgium are<br /><br />kemmel 23% max on cobols several 100's of meters with average 20%<br />Koppenberg Cobols max 22% 300meters stretch of 19% average, has been restaured and cobols are now easyier to ride up(still most toerists walk up ) <br /><br />La Redoute 17 max 10% average over 1650meters<br /><br />Other killer down hill then over a bridge 90 degrees left 90 degrees right and then al of a sudden a 400 meters stretsch at 20% in front of you the velomediane is invisible from the bridge and suprises lots of bikers who become walkers <br /><br />
