Great starter bike, with minimal issues

Fantastic starting bike

Poor store service

used for 3 to 6 months After completing around 200 miles all the spikes gave way in the front wheel. After speaking to the Oxford store they told me it would be a warranty replacement due to only owning for 3 months. Later that week I dropped in to the reading store to be told the specialists wasn't in and they couldn't help me. So, after a 20mile drive home I awaited a call. 2 weeks passed and still nothing. I called the store to find out what's going on and they said they would get the specialist to call me... 48 hours later guess what... Nothing! Another 40 mile round trip to reading to actually talk to someone resulted in them giving me a new wheele that's vale was only £29.99 in the first place! Would have been cheaper for me to have brought a new wheel in the first place!!

Basically, if you have an issue don't go to the Reading store, just buy a new wheel!

Decent bike, poor set-up

Good frame, decent tyres at the price

Poorly set-up by staff in shop

I've had my Triban 500 for 8-ish months now and it's actually a good bike at the price point. The frame's solid, the tyres aren't dreadful and actually hold up reasonably well while commuting, and the Shimano groupset is a joy to use.

However, my bike was appallingly badly set up by the staff in the Decathlon store I bought it from. The crank spacers were incorrectly fitted and the bike very quickly stopped shifting up to the outer chainring. The chain itself was too short resulting in very clunky and rough gear changes.

I took it in for the free safety check and none of those things were noticed by the workshop staff. It was only after I took it to an independent workshop that the poor assembly job was discovered and, since then, it's been an utter dream to ride compared to the rough and clunky way it was originally. Just very frustrating I had to suffer a poor quality ride despite Decathlon servicing it until I paid £65 for a proper service elsewhere.

I'd strongly recommend the bike for the price but would suggest budgeting for the cost of a general service at another bike shop to have it properly set up. Judging from other reviews, it seems like poor assembly in-store is a recurring theme with Decathlon.

Low stock warning non existent? Very Annoyed!!

used for 1 week or less I have recently been very actively looking at purchasing this bike.

I was going to purchase the bike in size 57" this weekend coming and thought i would check the site to double check availability

Size 57" is now unavailable and the bike has been discounted by £100!!

I am very annoyed because there was no warning of low stock and now i am unable to purchase this bike in the size i need.

Rear derailleur nightmares.

First fix was ok

Repeated problems

used for 3 to 6 months I switched from a Triban 3 to a Triban 500 SE after the rear derailleur snapped and threw me off my bike and into hospital. The Warrington store replaced the bike in January but offered me no more compensation for ripped clothing and broken mobile phone, let alone the serious lacerations and bruising I suffered.

Into april and the 500 started to click and grind around the bottom bracket. I live up in Kendal and I contacted the Warrington branch to see if I could take it into my local bike shop and if they would honour the repair. They refused saying it had to come to the store but were prepared to collect and return the bike. I'm training for the Fred Whitton this month so I tool it down and left it with them. I got the bike back 5 days later working but today, ironically the rear derailleur jammed in the spokes and nearly threw me off again. Three hours of trying to repair the twisted derailleur and with 10 days to go to the Fred Whitton I'm thinking I wish I'd not read all those glowing reviews of the Triban range. Should I persevere or ask for a refund?

Response of the brand

Dear sir,
I am sorry to read that you've experienced repeated issues with you rear mech.  I have contacted the store concerned directly.
We will be in touch with you very shortly as we need to do as much as we can to get you back on the road quickly and enjoying your bike.

used for 2 to 8 weeks Just wondering what is the maximum width tyres I can use on this bike?

Response of the brand

It does depend on the brand and you also need to consider the fact that tyres do stretch a little over time.  The bike is fitted with 23mm tyres as standard but it will accept 25mm profile tyres.  28mm can fit but not recommended as the clearance between the frame and tyre is too small.
At the point of sale you need 3.5mm clearance between the tyres and the frame/points of contact to conform to EU regulations.
I hope this helps.
