| MIXED FRAMEWORK |
With a very marked top tube inclination, over a very wide range of sizes (from S: 1m55 to XL: 2m00 ),
the frame of the EXPL 50 mountain bike is MIXED.
|
| LIGHTWEIGHT, COMFORTABLE AND PLAYFUL FRAME |
It isn't always easy to get the right position on a mountain bike. Our designers have designed a brand new frame that is easy to step over.
This 100% aluminum CGF (Comfort Geometry Frame) frame is both comfortable and easy to handle. The inclination has been studied to keep your back straighter while the rear chainstays are shortened to ensure good agility of the bike in turns. |
| Derailleur and drive train |
3 x 7 speed chainrings, 21 speeds total!
2 easy-to-use grip shifters on the handlebars.
Left (chainrings): control ascents/descents.
Right (speeds): more precise control over your pedalling.
Details: -Triple-chainring chainset (22/32/42 teeth) + protection / grease.
-Microshift FD-M20 front derailleur
-Microshift RD-M25 rear derailleur
-Microshift MS25 grip shifters with speed indicators
-Shimano TZ500 7 cog cassette, 14 to 28 teeth
-Large, solid KMC Z51 chain |
| Front suspension |
The 80 mm front suspension allows you to overcome your first obstacles with peace of mind on slightly uneven trails.
Its mechanical spring is a stamp of reliability. And the fork is particularly easy to maintain. |
| 27.5" WHEELS & TYRES FOR DRY TERRAIN |
The wheels of the ST 100 are tolerant and sturdy, with 27.5" double-walled rims with 28 spokes. Slow down without worrying about obstacles: small rocks, cracks, holes and bumps! Because you're getting started with MTB touring on dry ground, this mountain bike is equipped with DRY 27.5 x 2.0 tyres. Their performance is optimized thanks to a very rolling central part, while their side studs provide good grip in turns. |
| V-BRAKES WITH PADS |
Two V-Brake pads for effective braking.These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.
Thanks to the special design of the ST 100's aluminium brake levers, you only need two fingers to brake.
Once a year, check how the pads are wearing. If the grooves are disappearing, take your bike to your local store's workshop. |
| HANDLEBARS, STEM, GRIPS |
With a stem that tilts 10° upwards, the riding position of the ST 100 is raised, accessible, and comfortable.
In detail:
-Aluminium stem, 90 mm long, with a 10° angle for maximum comfort.-620 mm wide steel handlebar, for stability and control.
-Grips in "soft touch" material' for good grip and a soft comfortable feel. |
| Saddle |
The saddle of the ST 100 is welded to prevent any movement of the saddle.
And because your comfort is our priority after your safety, we've added an exclusive wider Ergofit saddle with a hammock shape.
Easily adjust the height of your saddle with the Flex steel seat post, either 350 mm or 400 mm long (according to the bike size). Its reduced diameter of 27.2 mm provides your seat with natural flexibility, 30% more than a standard solution. |
| Platform pedals |
The Rockrider ST 100 mountain bike is supplied with hard resin platform mountain bike pedals for added lightness and safety.
If your foot slips off the pedal, you will be less likely to injure yourself. |
| TRANSPORT and STORAGE |
We added a quick release system for easily attaching/removing the front wheel.
There is a nut at the back to secure the bike and limit the risk of theft. You will need a spanner to remove the rear wheel.
Our advice: a bike carrier is a simple way to transport your mountain bike easily, without dirtying your car. |
| Accessories |

To adapt the bike to your height and size, try these tips:
1/ Sitting on the saddle, you should be able to touch the ground with the tips of your toes.
2/ To adjust the saddle, your knee will be slightly bent with your foot on the pedal in the low position.
3/ If you hesitate between two sizes, choose the larger size. |
| Photos non binding |
As for the 7 cog cassette with 14 to 28 teeth, the photos or videos on the description of the bike show a Shimano TZ500 cassette. However, due to supply difficulties, the bike can be equipped with an equivalent Wheeltop cassette . |
