used for 2 to 8 weeks I bought this couple of weeks ago and i'am really happy about it .
I would like if possible to change parts to take weight of the bike down a bit .
Would someone , like a decathlon tech guy , give me advice on which part to replace to make the bike lighter ? And give me the name of the products from decathlon ?

Thanks in advance .

used for 1 week or less I ordered this to replace a RR 340 which I was not impressed with, the adjuster on the forks was broken on arrival and looked flimsy.
The 500 online shows a new fork with a riders weight indicator, which seemed an improvement. So I ordered one, wrong bike arrived, returned and waited for the 500. It arrived with the same poor forks as the 340 had! very disappointed and returned again. Time to try another brand I'm afraid. I wouldn't recommend Rockrider.

Response of the brand

Dear Sir,
I'm sorry to read that the bike came with the forks without the weight adjuster.  The only technical difference bewteen the two is the dial but the internal workings are the same .  There will be no difference in performance.  You still have a pre-load adjuster (which does the same job) but does not have the weight on in.  Some batches have the previous fork version by the sounds of it.
I will contact the supply manager to inform her of your experience.

Peter Lazarus UK Cycling Market Manager DECATHLON

Will get one in future

I have a 2010 career Vulcan which I love and we'll maintain.
Recently had to buy a freehub body for it, wife had car, so thought why not take one of my son's lol.
Was either another Vulcan or the rockrider 500 I could use to get the part for mine.
I went for the 500 merely has it looks good with the grey and blue touches.
When my son first got this 500, I always looked at it and thought, tasty looking bike.
So got my chance with teenagers agreement haha and I was very happy how it rode.
Smooth all round like my Vulcan, seat on the 500 I say is more comfortable.
Only issue I would raise are the grips which are lines grooves after so long they were annoying to my palm.
Vulcan ones are lovely.
That's it, my only moan.
The price difference to my Vulcan, it is one I will be looking at as a replacement, if I ever let my career go.
Btwin are really nice looking and perform well.
