Triban 500 - my first road bike

High quality spec, cool markings, triple on front

Gearing a bit high for steep hills

used for 2 to 8 weeks For £430, less tax on the cycle to work scheme, this is a top quality road bike. As well as commuting, I took it on a 40 miler last weekend and, although this is on the long side for me, I found the riding position comfortable throughout. The gears were smooth once I got used to the changer. The shop recommended the frame size and this is spot on. I had to stand up on the steep hills, which I don't like to do, and could have done with a lower rear cog as an option. I might change it. It looks great and got admiring comments. The matching accessories are really good value.

Excellent bike, worth a lot more than it costs!

Unbelievable value, despite being a "house brand"

Didn't really like the pedals.

used for 3 to 6 months This is a fantastic bike, really quick and light, good choice for a beginner-intermediate rider. Similar spec bikes can easily cost you up to £800 or so. Decathlon doesn't have many stores close to me which is a shame, but the delivery took under 48 hours which is amazing. Very easily to assemble and set up. Only one downside is that the paint scratches really easily so you do have to be a little careful and not bash it around.

If your budget is around £500, get this bike and a few accessories while you're at it. You will not find a better bike under £450 (unless on sale) so just go for it, you definitely won't regret it.

Bargain serious road bike

Light, good quality components, well built

Poor quality tyres fitted

used for 7 to 12 months A lot has already been said online about this bike, and as it was my first foray into a road bike i've been highly impressed with it. It's light, has great quality components, it appears to have been very well built and I've done 800 trouble-free miles so far.
My only gripe was that I don't think the supplied tyres are the best and I quickly changed them for Michelins, I'd have paid a bit more to have them fitted as standard but I guess cost is everything at this end of the market.

Great Bike, Bad wheels and Poor Workshop Service

used for 7 to 12 months I bought this as my first road bike in July 2014 and have covered nearly 1000 miles, it's a great bike in my opinion with excellent value for the cost, it is a joy to ride and looks great. Unfortunately it is let down by a poor set of tyres and wheels and poor mechanical support in store.
The initial set up was poor, the front mech mounted in the wrong place on the frame, rear mech needed adjusting as did the seat as no advice was given in store.
When the gears and brakes are configured correctly it rides excellently.
The supplied Hutchinson tyres were quickly replaced due to excessive punctures, they offer almost no protection at all.
After around 200 miles it became apparent that the spokes on the wheels had lost tension and buckled so i had to learn how to fix with a spoke key.
In January after around 700 miles both front and back wheels were making a loud grinding noise, I called the Decathlon Lakeside store who helpfully offered to take a look at the issue and give me a free bike service which i thought would solve all of my issues. The in-store Mechanic advised that this issue had been caused by lubricant and water getting in to the wheel bearings and was unrepairable, new wheels would be required at around £35 each. I declined the new wheels but went ahead with the service anyway which was a bad idea as when i received the bike the front and rear mechanisms both needed adjusting and the brake leaver tension was so high that the levers barely moved. After undoing the damage done by the service and some adivce from my local bike shop I had a go at cleaning out and regreasing the wheel bearings. Both sets of bearings on both wheels were completely rotten and rusting and had to be replaced and regreased at my own cost. It seems that this issue is caused by a lack of waterproofing around the hub and not enough grease being applied during manufacture.

In short this bike is a great purchase if you know how to adjust/repair road bikes or if you take it to your Local bike shop for servicing. Also replacing the wheels seems to be a good idea which i plan to do for the summer.

Although this review seems overly negative I am pleased with the bike.

Great bike rubbish wheels

4 5

Bought this bike as a starter on the road bike scene, have been so pleased with such a good bike for the money!
On the down side the wheels and the spokes are rubbish and have come loose and are unsafe to ride!!!!
As for the rest of the bike I love it and now have a top end road bike and I enjoy this just as much.
