A few improvements needed to make a great bike

Frame, fork, Shimano gears

Wheels and brakes weak, no mudguard clearance

used for 3 to 6 months I bought this bike in the middle of summer off the back of good reviews and it's relatively low cost. It is really smooth to ride, light, generally very good and all in all I love it, beats sitting in rush hour traffic and keeps me fit without needing to hit the gym. However, the wheels as many people report fall apart in less than 250 miles of commuter use on british roads, soon buckle, wobble and lose spoke tension. I couldn't be bothered with a replacement under warranty as they'd only put the same ones on again so upgraded to Fulcrum Racing 7s and they seem a lot better thus far. The Shimano Sora gearset is great, easy to use and accurate. However the Shimano brake pads are rubber throughout with no metal shoe so are fairly weak - not the bikes fault, just a commonly reported downside of Sora. I replaced these with some low cost Clarks CPS240 which do a better job. Finally there are eyelets built in to the forks to allow mudguards to be fitted but there is not enough clearance between the tyre and the fork/brakes to fit them so pointless, just about managed to half fit some SKS Chromoplastics but couldn't get the front wheel covered fully. Overall this bike is a low cost bike but I feel certain compromises have been made to make the price point. Still, even if you upgrade the wheels and sort the brakes it is still far cheaper than other road bikes of lesser spec so do go ahead and buy it, just investigate and budget for upgrading some of the components listed above as well. Decathlon staff in Bolton were very friendly on all occasions I've been in.

used for More than 1 year I have been riding mine for over a year now - it is a fantastic bike. Great value for money. Fast, reliable, great handling. But the supplied wheels are nasty. Back wheel came untrue, and although Decathlon replaced it immediately with no quibbles, but it happened again after a few weeks. Front wheel was fine, that said. But, I now ride with a set of Shimano R501 wheels which are terrific, and make it a really great bike.

Excellent commuting and beginners triathlon bike

Light, comfortable, great price

Nothing so far

I wanted a bike to commute 20 miles per day and use for my first triathlon. Having read various reviews this bike eventually came top of the list based on the highly rated components and great overall reviews - I haven't been disappointed.
It's been about 4 months since I bought the bike and I've used it in all weathers for commuting and racing. When I bought it from Decathlon in Oxford a very knowledgeable staff set the bike up for me and gave me plenty of racing tips. I brought it back for a service after 3 months and the front wheel bearing were making a slight grinding sound (I didn't notice until it was pointed out).
Since I didn't live in Oxford (I was there for a race) and couldn't afford to stick around while they resolved the issue they gave me a brand new front wheel which has been working perfectly.
I was very impressed with both the bike and the service offered by Decathlon staff.

used for 2 to 8 weeks I would of expected the wheels to stay intact for a much longer duration.
