Good bike, shame about the service

used for 1 week or less I've just bought the bike so can't say too much about it yet. I nearly never bought it however because of the service I received. I was buying a number of other things with the bike and when I asked if they could do a deal on any of it the sales chap had t get the manager who then gave me a lecture on how he could easily sell the bike to someone else. They went to fit some free lights but the front one was awful so I asked again if they'd do a deal on the lights only to get the same lecture. Eventually they did throw the lights in for free but there was a very bad attitude. The chap setting the bike up didn't use the proper clamp available and when I picked up my new shoes the bike slipped causing a very small scratch, not impressed. If the proper clamp had been used it would never have happened. The gears have not been adjusted properly and I'm not sure the guy in the shop would've known how to do it properly. So, at the moment it looks like a very good product spoiled by rubbish service. Doesn't help there is no email contact available for customer service.

Wheels on Triban 500


Loose spokes and awful bearing seals

used for 3 to 6 months Purchased a Triban 500 in August 2014 and within a few weeks found the wheels out of true and loose spokes. Had these tightened and wheels trued to then have serious grinding in the rear hub after 5 months. Water has got into the bearings as there was insufficient grease and poor seals and has corroded the bearings and damaged the bearing cup. Not happy to replace like for like as have no confidence in these wheels and Oxford store will only offer me upgraded wheels at the current sale price with notihing in compensation for my damaged wheel. Real pity as I love the bike but not the wheels.

Excellent first road bike

Very well equipped and put together

used for 2 to 8 weeks I bought this for my son's Christmas, and he is delighted with it as a first road bike. I am an experienced road cyclist, and can't believe what a good bike this is for the price. Most road bikes have gears that are too high for a beginner, but the triple chain set means the bike comes with a low bottom gear, and if a lower gear was needed, it is comparatively cheap to swap in a cassette with more teeth on the largest sprocket to get even lower gears. I read some reviews saying bikes poorly put together when bought on-line, but the Edinburgh shop had assembled my son's bike extremely well. All we have changed is the stem (£15 part) to make the handlebars easier to reach until he grows a bit more. Superb bike- highly recommended

Extremely good value for money, once size correct

Great spec for the money

Tweaks and some upgrade of components required

used for 7 to 12 months First road bike since my teens, did a lot of reading around the subject, spoke with some cyclist friends and settled upon this as opposed to looking at an older 2nd hand carbon bike for the same sort of money.

Went to Decathlon Lakeside, young lad there was very helpful re accessories etc. Was borderline 60 or 63 frame (6ft 3 and a bit), unsure from a few laps of the store, ended up going for the bigger one then regretting it when found myself over-reaching on first ride. Phoned store up to explain the situation, took it back in and they swapped the wheels onto a 60 frame which I am now extremely happy with.

Had to play around with front and rear derailleurs to get them right, which could and should have been sorted in the set-up. And now, 6 months / 1000 miles in I have ended up fitting SPDs, and replacing the puncture-prone tyres with Schwalbe for the country roads I do most of my riding on. Next up the wheels - no failures as yet but they do seem flimsy - and probably the saddle which although I've got used to it is quite unforgiving.

The above minor quibbles / upgrade spend aside, it's a great bike which I have very much enjoyed riding. It looks good, rides well and as mentioned in another review I've shed the few kg weight difference between this and a carbon bike and saved myself 1000 quid in the process.

Quick mention for the Decathlon cycling clothing, which I've found great value for money: currently rocking the 300 bibtights the 500 long sleeve jersey and the 700 gloves, all of which are keeping me good and toasty in the middle of winter.

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.
