Great bike

Came very quickly and was well packaged, very easy to assemble, attach handlebars and pedals. I did not use ones supplies as I use toe clips. The bike handles well with a very good riding position. Microsoft gear change very easy to use and an excellent range of gears, including a 34 tooth crawl gear!Disc Brakes are very effective and easy to apply. An outstanding bike with nothing near its quality for the price.

Great bike for the money!

Bought as a 2nd bike for my son. 500 miles in and no problems. Well set up on delivery - I'm a tinkerer (and Cytech qualified mechanic) and all that was really required was turning the bars and setting the saddle height. Even the mechanical disk brakes were well aligned.

Rc120 disc road bike

Still not sure on the Matt paint finish, would have preferred a metallic, but living with it. Bike performs well as expected, had low pressure in tyres after first ride, due to the valves not tightened (poor initial set up from decathlon)also on collection from retailer the from wheel was off centre and had to be realigned with an adjustment of the disc calliper also needed. So can recommend product, but more attention needed on safety issues at the pre-delivery point from Decathlon.

1st Road Bike in 35 Years.

Used to race Mountain Bikes but too hard on the road. Did some research and the RC120 seemed to be a good buy. I’ve had it about 5 months now and done over 300 miles on hilly Yorkshire roads. Am a lot fitter now and even lost a few pounds. The bike has been good with only the niggle of a broken right shifter that the Worksop changed under warranty. Bike is like new again and I’m more than happy with it.

Good bike

High quality materials, I’m so impressed with this bike, so comfortable when riding and also brings high speed and versatility. Probably one of the best bikes when starting your trip on this amazing hobby Perfect if you want it to go work / if you will use it for trips it’s a beginner bike so don’t compare it with high price bikes. I’m happy with my purchase :)

Fantastic bike, at a fantastic price!

It might have it's foibles, but it's no slouch. This bike is both a perfect entry into road cycling, and a great second bike for today already accustomed to the sport. Don't let the lack of Shimano groupset fool you, the Microshift R8 derailleurs and cassette are more than adequate, I'd even go so far as saying they're better than the equivalent Shimano Claris arrangement. This bike has everything you might want in a road bike at a steal of a price - disc brakes, light weight (at this price point), a decent groupset and (unlike any other bike under £500) tubeless ready rims; a £100+ upgrade at least to purchase separately

Bike purchase

Fortunately I travelled to Sheffield to pick up first order however they had wrong g size But in hindsight the two bike technicians there recommended a large rather than a medium for the model I was purchasing. Proved to be good advice So all is good - my friend - the bike was a great fit - loves it - so all is good

449£ for less than 7 days of (frustrating) use

Do not buy this bike. 1. The gears don't change properly. I spent 2 hours 'fine tuning' the gearing mechanisms to try to make this bike rideable but there are quite a few defects that are not down to tuning, but bad, cheap, messy design. 2. The back tyre burst after the 7th day of use. For 449£, you got to rationalise why it "isn't so bad", so I figured I'll just replace the tyres and live with the gears. I am now wishing I had read more of the bad reviews. The tyres are apparently hell to remove, and so many other things have apparently failed for people after just a few weeks of use. If you want to play with death by using this on busy roads, or just fancy throwing 449£ down the toilet, this is definitely your choice.

Don't get a puncture

This bike is decent for the money, but the tyres are extremely difficult to get off the rims if you need to change the inner tube. I got a puncture after riding the bike back from the store. I have managed to change the inner tube but it took me about 90 mins + lots of elbow grease. Amazed I didn't burst the other inter tube doing it as I had to be pretty heavy handed. So it is doable, but certainly not looking forward to it happening again (especially if I was out on a ride). Gears change smoothly, and it's comfortable to ride so far (yet to take it out for more than an hour) but compared to my other bike it feels great. Still recommend this despite the inner tube issue, but just an FYI!

Hi Jamie, I have the same wheels on my bike and I can confirm that the tyres are a tight fit. You should find that after they've been removed once the beading will stretch a bit and it will become easier. Really glad to hear you're enjoying the bike apart from that, remember any issues are workshop team are here to give you a hand.

Have a great week!

has put me off cycling

I purchased this bike after finding my past love of cycling renewed during the lockdown I didn't have the largest budget so this bike looked ideal, unfortunately it has issues To begin with there was, what I thought was front derailluer, chain rub, my local cycle mechanic came out to check the problem, it turns out it is the chain rubbing on the front cassette in several gears, so could not be adjusted out As the gears in question are more or less duplicated in other gears i decided that I could live with it, but it is still mildly annoying But then the front brake pads started to rattle in the caliper, which led me to discover they cannot be removed until they are worn down, at least without totally dismantling the caliper, which is beyond my comfort zone As I cannot afford to get it fixed at the moment, the bike has been put to one side and I'm back in my car, which has left me feeling disappointed in my purchase choice as I do not think I had travelled 100 miles on it before the second issue Maybe I just got unlucky and recieved a bad bike as I bought it when bike stocks were low

Great bike for a step up towards serious biking

OK, so perhaps it's not a top end sport bike. But it's ideal for a beginner or 'born again' biker looking for a keep fit and weekend bike - possibly even touring or mild racing, but that's outside my experience. I am 5'8 so on the cusp of the Small and Medium sizes. I chose Small and it fits me pretty well. If you follow the video it's easy to complete assembly, although I could have done with a video on how to use the gear changers. It's important to bed the brakes in otherwise you just won't stop, and it's a shame you have to go looking for videos on how to do this although it's common sense, really. The saddle is great - the best of four I've had in the past, so you shouldn't need to change that. Tyres are good and haven't punctured, yet! You may well need to index the gears to get them running quietly and efficiently. My one minor beef is the choice of gears. For me personally it took a while to find a gear that gave me the right cadence for mile munching on the flat and up mild hills. My last bike had a 'Goldilocks gear' that was perfect for me. On the Triban one gear was too low, one was too high. But you get used to what you've got in the end. In summary, great bike, you can't go wrong for the price. Weak point: instructional videos / instructions could be more comprehensive.

Get something else if you want to change tyres

Unfortunately I have to warn people to not buy this bike. I got a puncture on first day, so I decided to get new tyres as i can understand that a cheap bike will have bad tyres. After 3 hours, lots of soap, 2 people, some very big painful blisters, 2x 1 hour round trips to decathlon store workshops, and the tyres are still not on. One workshop did manage to get it on but popped the innertube and didnt have a replacement to give me. So I am left with a bike that I cannot ride. A quick look on the internet (these reviews and reddit) and there are countless other stories on this problem, one man burst his finger open and had to cut his brand new tyres off. I regret ignoring these stories now. Long story short, if you want to replace the tyres (which you will unless you like punctures) then get another bike or you'll have to spend £150+ on a new set of wheels that fits the bike - which puts this bike at the same price of a Trek with shimano gears. Sadly for me, I'm stuck with a bike that i used for 3 miles, and is now junk and decathlon will not replace the wheels.

Starter Bike

I got this bike as a beginner and don't plan on doing any super fast races etc. so it's perfect for my needs. I'm a 5ft3 woman and the XS is great and I don't think it's necessary to buy a woman specific bike. However, a couple of comments. It arrived without pedals, lights or a bell as advertised on the site. But with an email to Decathlon, they quickly resolved this and sent the missing parts out a few days later. I have had some issues with the chain and gears slipping. The chain was rubbing on the front derailleur when in a higher gear and the back gears would slip when riding along. Although Decathlon do offer 3 months free service for new bikes, which is great, with everything going on it made it tricky to get to a store due to our closest stores being closed still. But buying a new bike you'd hope not to have any issues. I guess that fact it gets delivered in a box doesn't help. I had to get a bike shop to look at it and they think it's a great bike, it has some Shimano bits and pieces, however, they did say the drive train isn't great quality. Perhaps something to upgrade if I get into cycling more seriously. Overall a good bike for what I need it for.

Really good bike!

This is my first road bike and for a first bike, I can honestly not fault this bike. First of all, it is a very good looking bike. Brakes and gears are really good. The only thing that annoys me that they are not shimano but this doesn't mean they don't perform well, it just annoys me! Apart from that everything is great. It is very light bike and always ready for a challenge whether that is a hill climb or a sprint. Obviously you wouldn't go for this bike if you are a pro but considering you can spend nearly £800 for the same spec with other brands, this bike is an absolute steal!
