Real simple one: medium size mountain bike that feels like its going to tip backwards up steep climbs, to the point the front lifts off the floor.

How to rectify? Longer stem?

What bike is it and how long is your stem? I personally like a short stem so would look at lowering the stem instead.
Also, you aren't one of these kids that have their seat way back and tilted back?

Roadie normally. Saddle is flat and normal.

Stem, not sure. Short.

Please don't take this the wrong way but - technique - if your not used to riding off road you may not be used to the amount of body English required. For steep climbing you want to be right over the front of the saddle, and try keep your elbows down.


But yes, if you are looking for parts that will help, a longer stem will do that.

I found a cheeky little hill that had me facing this issue on my roadbike the other week, made my legs smart a little bit.

Its a fair point. I'm probably sat in a typical roadie position.

The bike looks like a Scott Scale? Typically an XC bike, the stem look fairly short and there looks like a lot of sweep on the bars as well. If you havent had the bike from new its possible that is has been modified, if the stem is less than 70mm it might be worth putting a slightly longer one on and possibly change the bars for something with less of a sweep.

It is, I've had it since new.

Yes to both, stem is short and bars sweep back.

You could get one of those straight XC bars. The bike actually looks fairly low and XC at the front.
As the others said, a bit of technique getting your chest close to the bars will help.

I think its mostly technique, but I could do with a bit of help too smile

weight forward and smooth pedalling. IME I rarely used the very small ring at the front 'cos it meant you tend to either break traction, or lift the front..

Similar riding position to mine - Giant XTC hardtail of 2004 vintage, but not much original on it!

Depending on how leaned out you are on the frame you can get a similar effect by fitting a straight seatpost instead of the backset one on there. That'll put you more square over the cranks.

Mine's a work in progress at the moment - ordered an inline seatpost (changed the stem and bars a couple of years ago as my wrists were taking serious grief!) but it needs to be further into the frame than the current one, but I ordered a shorter one....waiting for Wiggle to exchange for the 400mm option.



Depending on how that goes I may need to rotate the handlebars forward a touch, or go back to the longer stem

Surprised there have been this many replies and nobody has asked how tall you are?

Thumbs on top of the bars. Usually helps with front wheel lift on the really steep stuff.

Like others have said get you weight forward on the saddle and get low over the bars, it'll help stop the front lifting.

There's a short, sharp fireroad climb at Swinley where I used to have the same problem but after a bit of practice it's easy to clear.

How tall are you? If that is a medium frame you with that seatpost height I am guessing 6ft?
If so perhaps the medium is a bit small? Large frame will make bike longer and less wheelie prone.
It also allows you to keep seat position forward on a larger frame.

if you are shorter than 6ft, try lowering that seatpost a half inch, that will reduce front lift on steep climbs

I'm 5'10

Didn't have an issue (except crashing) tonight using the tips above. Might get a slightly longer stem to help a bit too.
