Technical Information

1
THE STORY BEHIND THE RR340 MOUNTAIN BIKE
This mountain bike was fully designed and developed at the B'Twin Village (Lille, France) and is the brainchild of an expert team of mountain bike enthusiasts. To give beginner mountain bikers the lightness and ease of use they need, the team got beginners involved at every stage of design, construction and testing for the RR340. Whether it's for riding alone, with friends or as a family, users have approved the RR340 as being really fun to ride!
2
A UNISEX MTB
The RR340 mountain bike is designed for men and women alike. The RR340's frame has been carefully designed right down to the smallest detail, from the top tube's relatively pronounced slope, to the broad range of sizes (XS: 1.45m to XL: 1.95m) and the low weight to suit both men and women. For even more comfort, the ROCKRIDER team's female members recommend using women's SPORT 500 saddle which is specifically designed for women.
3
HOW TO CHOOSE THE RIGHT SIZE RR340
Several sizes available: XS: between 1.45 m and 1.50 m S: between 1.51 m and 1.65 m M: between 1.66 m and 1.75 m L: between 1.76 m and 1.80 m XL: between 1.81 m and 1.95 m Do you weigh more than 90 kg? For your comfort and safety, "double-walled" rims (more durable) are a good idea. The Rockrider ST100 mountain bike will be even better for you.
4
A LIGHT, EFFECTIVE FRAME
To get the most out of your pedalling, the ROCKRIDER 340's frame is made from 100% aluminium. Aluminium combines durability and a low weight. Its sloping geometry makes it easier for both women and men to mount.
5
FRONT SUSPENSION FOR CUSHIONING LUMPS AND BUMPS
The SUNTOUR XCT 80 mm front suspension is designed for slightly uneven trails and helps you overcome your first obstacles with no worries. Its design, based on a mechanical spring, is reliable and easy to maintain. You can also easily adjust the stiffness using a dial.
6
REAR SUSPENSION: NONE
This mountain bike has no rear suspension. It is a "semi-stiff" mountain bike: ideal for beginners. Compared with a full suspension bike (with rear suspension) the benefit is clear: it weighs much less so you waste less energy on flat terrain. A "semi-stiff" bike such as the RR340 is therefore a good choice for your first rides!
7
DERAILLEUR & DRIVE TRAIN: CHANGE CHAINRING AND COG
3 chainrings with 7 cogs, so 21 speeds! 2 simple grip shifters on the handlebar. Left (chainrings): manage your climb/descent. Right (cogs): adapt your effort more precisely. In detail: -Triple 22-, 32- and 42-tooth chainring + protection / grease -SHIMANO TZ30 or MICROSHIFT MS22 front derailleur -SHIMANO TY500 rear derailleur -SRAM MRX21 grip shifters with speed indicator -SHIMANO TZ21 7-cog, 14- to 28-tooth cassette -Wide, sturdy KMC Z51 chain
8
STEM, HANDLEBAR, GRIPS: FOR GOOD HAND POSITIONING
With a stem that tilts 10° upwards, the RR340 gives you a raised, accessible, comfortable riding position. In detail: -90 mm (in sizes XS and S) or 110 mm (in sizes M, L and XL) aluminium stem with an angle of 10° for maximum comfort -600 mm-wide steel handlebar, for stability and control -"Soft touch" grips for a firm yet soft and pleasant grasp
9
SADDLE: SIT COMFORTABLY!
Your comfort is our top priority, which is why we offer the exclusive, wider ERGOFIT saddle, with a special "hammock" shape. Easily adjust the height of your saddle with the 350 mm-long, 29.8 mm-diameter seat post.
10
V-BRAKES: CONTROL YOUR BRAKING
Two V-Brake pads for effective braking. These brakes are composed of two calipers that can exert varying degrees of pressure on the rim to slow the bike or stop the wheels from spinning. Thanks to the special design of the RR340's aluminium brake levers, you only need two fingers to brake.
11
26" WHEELS & TYRES FOR DRY GROUND: READY TO ROLL?
Push off easily on trails with your RR340 mountain bike and its light 26-inch single-walled wheels. To keep these wheels sturdy, our engineers have given them 36 spokes! Because your first rides will be on dry terrain, the DRY 26 x 2.0 tyres are the most suitable. Their performance has been optimised thanks to a faster central section, while their side lugs offer excellent traction in turns.
12
FLAT PEDALS
The Rockrider 340 MTB comes with flat mountain bike pedals made from hard resin for a lighter weight and greater safety. If your foot slips off the pedal, you're less likely to injure yourself.
13
EASILY TRANSPORT AND STORE YOUR BIKE
At ROCKRIDER, we know that not all rides start on your doorstep or at the front of the store. You might need to transport or store your bike in a confined space (car boot, porch, etc.). To make it easier to mount / remove your front wheel, we've fitted it with a quick release system. 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 back wheel.
14
WEIGHT
14.5 kg in size XS without pedals. 14.8 kg in size S without pedals. 14.85 kg in M without pedals. 15.0 kg in size L without pedals. 15.2 kg in size XL without pedals.
15
ACCESSORIES
Your BMX RR340 comes with a derailleur guard, chainwheel protection (to prevent dirt getting onto your clothes), bells, lights, wheel reflectors and pedals. The frame is compatible with: -Front and rear mudguards -Stand -Bottle cage -Saddle bag -Rear pannier rack -Child seat etc
16
COMFORT & SAFETY
We recommend that beginners wear cycling shorts with a pad (foam in the shape of a saddle) or a gel saddle cover to reduce soreness. For longer rides, remember to take something to drink (e.g. a water bladder or bottle). In all circumstances, even for a short ride, wearing a helmet is essential!

Stockage tips
After washing, rub with a dry cloth to remove all traces of moisture. Store your mountain bike in a cool, dry place, away from corrosive products and salty air.

Maintenance tips
Regularly maintain your fork (clean and grease dampers), especially in winter. Take your bike to your Decathlon store's customer service workshop, which offers a free safety inspection on all new bikes purchased.

Bought this for my 11 year old son. He’s over the moon with it. I got it with the small size frame, fits him perfect. A great looking bike. Love the Matt colouring. Looks like an expensive bike. Great for the price.
Poor build

Hugely uncomfortable seat, horrendous gears, general poor build quality. Everything shakes and makes noise including the bell when not in use. Obviously wasn't expecting much for the price range but wouldn't have expected it to be as poor as it is .
Response of the brand
I'm sorry to read that the bike does not live up to expectations. This is a hugely popular bike but on this occasion, the set up was not up to the level we would have expected. I gather we have arranged collection of your bike.

I ordered my bike on Saturday and it was ready for collection on Monday. Fully assembled. Really pleased with rockrider 340. I wasn’t cycling for years but this bike is really easy to ride , it looks great and after adding foam saddle cover it is also comfortable to seat on. Great quality bike for very good price.

bought the bike for my sons birthday, collected it on 13/6/18 within a few days the pedal fell off so i put it back on, 2 days later i was off again took the bike back on 22/6/18 couldn't fix straight away so I'm currently waiting to hear back from them with a very unhappy 11yr old surely this shouldn't happen to a brand new bike
Response of the brand
Thank you for contacting us. It sounds as if the pedal was cross threaded. I'm unsure why this happened but I have asked the local store to contact you directly.
I'm sorry that this has spoilt your son's first few rides with his new bike.

Peter Lazarus, National Cycling Manager, DECATHLON

Appears to be very good, it’s for my son, he of course is very happy, quality looks good, although he’s only been riding it for a couple of weeks, so time will tell.
Best Budget MTB you can buy

I've had this bike for 2 weeks, and am very happy with it. Sometimes you have to remind yourself that it's a budget MTB, but it's easily the best value for money you can get for a new bike.
I have done about 40 miles on it now. I have done a few mods. I have changed the tyres for Schwalbe Land Cruisers as I intend to use it on the road as well as on tracks. I have put bar ends on the handlebars for comfort, and also changed the saddle.
The worst thing about the bike is the gears. The twist grip change isnt great, so I am going to replace them with trigger shifters, available from Decathlon for about £15.
The brakes also aren't fantastic, but they will stop you if you pull hard.
But this is a bike that cost £159.99. It's fine out of the box, but spend another £50 on it and you will have a truly great bike.
It looks great in the orange colour as well.
GOOD VALUE FOR MONEY

NICE DESIGN, SOLID BIKE SO FAR BUT ONLY TIME WILL TELL. THIS IS THE 2ND ROCKRIDER 340 IN THE FAMILY AND BOTH BOYS (10+ 11) ARE CHUFFED. ONLINE ORDER SYSTEM OK BUT DELIVERY ABYSMAL WITH LITTLE /NO INFO AVAILABLE WITH STORE PICK UP OPTION. STAFF AT STORE FAILED TO CALL BACK TO UPDATE ME BUT WHEN THE BIKE DID EVENTUALLY ARRIVE (5 DAYS AFTER ORDERING) THEY WERE BRILLIANT AND MORE THAN APOLOGETIC. STRONGLY RECOMMEND GOING TO STORES FOR ADVICE/ORDERING LARGER ITEMS.
