I have wanted a road bike after many years on the mountain bike and have been researching them for over a year. All the forums and bike sites kept directing me back to this bike. I took the plunge on loads of recommendations and got one -fantastic love it.

used for 2 to 8 weeks I bought this bike as a starter to take part in triathlons and found it was a lot lighter than my hybrid BUT i was getting aches and pains and friends pointed out that i was over reaching !,
Went back to Decathlon to buy a new smaller srem only to find my frame size 57 is fitted with a 130 stem not a 110 so was made and supplied wrong :-( Quality controll ? I pointed this out and the shop did fit a stem but it was out of the "spares odds and sods box" and is red and white not grey and blue so does not match colour of the bike so some what dissappointed :-( But no streaching SO CHECK STEM SIZE BEFORE YOU BUY

Response of the brand

Dear Sir,
I'm sorry to read that the stem was the incorrect length.  It is the first time that I have received this feedback.  
I will contact the b'Twin in France to see if we can find you the correct colour or neutral colour stem.  I'll be in touch as soon as I get a reply.

Excellent value

used for 2 to 8 weeks Great bike, quickly delivered. Sloped frame in 60 requires me to raise the saddle slightly above max line (I'm 6'2" with long legs). The gears need tuning but hopefully the free service will fix that. Excellent value for money.

Not Bad Value for the Money


Components wear out quickly

used for 3 to 6 months I bought one of these as a winter bike. Although I have ridden it through rain and muddy roads, I have always cleaned it after each ride. I enjoy riding it. However, it there are problems with the durability of the components. The freewheel failed after about 6 weeks. Decathlon replaced the whole wheel without any problem. However, after about three months and 1500 miles the cassette and chain were worn out. I have replaced these with better components, which should last longer!

I would normally expect cassette and chain to last at least twice as long. So decent bike for the price, but drive train could be better specced.
