I have fitted a 50mm stem and wider bars to my commuter mtb ( from about a 70mm stem and narrower bars ). I have moved the saddle back on the rails. Now when I ride I keep sliding forwards in my new upright position. The saddle is flat. I may just try angling the saddle up a bit and trying it.
If I unweight my seating position I naturally move towards to front of the bike. The bike fits spot on. May also try sliding the saddle forwards too.
Any ideas why?
saddle needs to be tilted nose up - but make sure your weight is still on your sit bones
Try just riding uphill.
Could be your bars are a little low. Can you try it slightly higher with some spacers under the stem?
Saddle should be fairly level. Having the nose too high can hurt your little gentleman. It's a fine balance I find.
thanks tj ill try that. Isn't that just a bodge though for a bad position.
The saddle needs to "cup" your sit bones, which means sometimes the nose needs to be up by a degree or two. The shape of the saddle matters as well, one of the most popular, which seems to suit most bums is Charge Spoon and it's slimline cousin Charge Knife.
Have the new bars and stem actually improved anything in terms of handling on the commute that is worthwhile?
thanks it's a WTB one that I find comfy. It has depressions in it for the sit bones. I'll try move it and sliding it forwards maybe too.
I like using the shorter stem as the steering is rapid and I like the new feel of it all much more. It's a year 2000 rigid mtb so it was designed for a longer stem.
NOt IMO. Its old fashioned but IMO the riding position dictates the angle of the seat
thanks all. I;ll try raising the bars too.
Just make one adjustment at a time. Don't worry too much about overall position as your body will soon get used to it.
Skills day

I have exactly the same problem end yet to cure it properly.
Tried: shorter stem, different seat, tilting seat up a little. Next to try higher rise bars.
Of course you could always use Tony Martins solution
Or maybe not
Any ideas why?
<geex-mode>You're being overly sensitive to minor changes in body position because you haven't learnt the ways you can handle your bike that require more extreme body positions.</geex-mode>

Stem, 20mm closer to your old saddle position
Bars, wider by ?? which means you're reaching a little bit further forward unless the sweep is different - shall we say, err, 10-30mm further away from your old saddle position
New saddle position, ??mm further back from your old saddle position
Total = your hands and arse may well be further apart than before, even if they are all a little bit further back so you may be more stretched and so at least "feel" like you're slipping forwards or even actually doing so.
geex never sits - surely we all know that ?
Hands are further apart, brining you forwards? Can you raise the stem or bars a smidgen?
the bars already have three spacers underneath them and are risers. Sold the old original bar and stem. I'll get around to making adjustments this weekend.
thanks.
Damn roo slow with the sand paper idea!
Why not just put the seat back where it was?
I am going to try that. I thought lengthening the cockpit might be a good idea.
