One word: spines. Almost everything that grows in these parts is covered with them, and this does not always bode well for your bike tires (and yourself). 'Slime' and various other anti-flat remedies really come into their own here. We especially recommend slime-filled tubes, since without them it is not uncommon to get ten or more flats per ride - in each tire! Bring some spares too, because once a slime tube gets a big puncture, it cannot be repaired.

There is no specialized MTB stores in Hidalgo, you will need to go to Monterrey to purchase spare parts and/or get your bike repaired (see local shops page). This will take a good part of your day, so it's better to come prepared.. Bring your toolkit and a selection of spare parts that fit your bike. Spare tubes, chain, spokes, brake pads, brake and derailleur cables, lubricants, etc. will probably come in handy. Bikes get a beating on the rough Potrero trails, so inspect your bike frequently.
