not had an SLX frame before. Super light and rides lovely, but I am little concerned at how much it flex's. When I brake hard (rear) or skid stop the cranks seem to flex. I have ruled out loose BB /cranks, bend chainring, bendy cranks, so the only thing left is the frame.

Anyone else had anything like this? Is it normal, is it trashed, is SLX not up to harsh road treatment?

753 reynolds is very similar wobbly flexible disconcerting but you get used to it after a while

check your wall thickness of the tubing, and give the chainstays a squeeze with the wheel out,

youll get a good idea of the the "mechanical properties" of your frame, important to know.

SLX, IIRC, is the "lightweight" version of SL.

A lot of the 80's CrMo tubesets were a bit flexi, which probably inspired the early Alu and Carbon frames (remember the Peugeot Fibre de Carbone? http://velospace.org/node/942)

If you lean the bike against a wall and apply some foot-based force to the end of the BB axle, the framewill probably deflect much further than you might expect.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
