Puddle of oil when left up side down The other day I left my mountain bike upside down overnight as I was changing a tyre. The next morning i had a puddle of what seem to be oil next to the handle bar. Does anyone have an idea where is this coming from? As far as I am aware my disk brakes are not hydraulic would it be from my front shocks? If so how do you replace, and is it safe to ride it now before putting some oil in? This is my bike: <

Presuming it came out of the bike, probably oil from Hydraulic brakes. Although the link does not specify things in detail - A 2009 bike with Tora Rock shox and Deore components would almost certainly have had hydraulic brakes.

Check the brakes are working and not spongy. If in any doubt take it to the LBS for a check over - a leak from the shocks needs fixing but would not be the same seriousness as a leak from brakes.
