Rock Machine Catherine 70 HD 27.5", model 2018
Women's mountain bike Rock Machine Catherine 70 with 27.5-inch wheels. Ideal for sports riding and trips with friends. For the new 2018 season, we applied the new Sharkspine EVO design to the Heatwave, Catherine & Crossride 500 models. Thanks to the shorter rear structure, longer upper frame tube and increased overall stiffness, these innovative bikes bring a great riding experience to an even larger circle of male and female cyclists. One of the key design features of the Sharkspine EVO is the ability to reduce the number of frame sizes due to the low position of the top tube at the junction with the seat tube. Thanks to the correct length of the cockpit and the simple lowering of the saddle height, even bikers with a smaller body no longer have to choose extremely small frame sizes.

All bicycles at the MTBIKER shop are new, not-ridden, from an official distributor and with a full warranty. Several brands even offer a lifetime warranty on the frame after registration. We perform all warranty services in MTBIKER stores after personal delivery or after sending the bike (or its part) by courier.
- The bicycle is taken out of the manufacturer's box
- The bicycle is assembled, inspected and adjusted (front and rear derailleur, shock, fork, wheels,...)
- The bicycle is carefully packaged back into a box and shipped
- If you order a bike for in-person pick-up or home delivery, the bike will be waiting for you assembled and checked
- If you order a bicycle via courier to your home address, the following must be done at home:
- Take the bike out of the box and carefully remove safety material and foils
- Mount handlebar to stem (1 minute, 4 or 5 mm hex hey is needed).
- Mount front wheel to fork (1 minute, without the need of any tools if the bike has a quick release).
- Loosen the screws in the headset, straighten the stem with the front wheel, tighten the upper screw on the fork and then tighten the headset (2 minutes, 4 or 5 mm hex key is needed).
- Mount the pedals to the cranks while lubricating the thread and carefully mounting it the right way (1 minute, 8 mm hex key or 15 mm wrench).
- Mount seat post to frame (10 seconds, without needing any tools if the frame has a quick link).
- Inflate the tires or fork and shock to desired pressure (2 minutes, pump needed).
- Check the tightening of hex keys and quick-releases (2 minutes, 4 and 5 mm hex key is needed).
- Go for a test drive! Handle your bicycle carefully until you get used to it. If the bike has disc brakes, their performance will be limited from now on - they will gain their full power after 4-5 strong brakes at higher speed.
