used for 1 week or less Hi,
Having read superb reviews for the triban 3, im disappointed to see it is sold out in all sizes on the white model but also the red one (this feed). I note that it is a popular bike, but is a few years old now so am worried it may be discontinued or that it is not being stocked any more. I have signed up to updates on each bike being available online, but am aware realistically it may be a lost cause. I am writing this post hoping to get an official answer on it, as i will get another bike if this is the case. I live in the south and am hoping for the 54 size! Any information would be great!

used for 3 to 6 months Wheel and a noise and wasn't as fast as the other bikes I was with. For a cheap bike it's good for the money.

Great Value But Change Saddle and Wheels


Saddle, Freehub


  (United Kingdom)


4 5

I've had mine for about 18 months now and use it to cycle to work (2 miles each way) plus occasional weekend rides. I replaced the saddle early on - original is not good at all.
Now I am having to change the freewheel hub, this is a shock to me as I have never had to do this on a bike before and all of my previous bikes have lasted for years.

Nice to ride, shame about the gears

Excellent bike for a beginner road cyclist

Gears difficult to set up.


  (United Kingdom)


4 5

The bike itself is a dream to ride, especially at this low price point, unfortunately the gears had not been set up correctly prior to shipping so the front derailleur catches the chain in top gear and it is near impossible to correct.

Good bike

The price point was perfect and bested Halfords

Saddle, no toe clips on small sizes


  (United Kingdom)


4 5

Saddle is atrocious, I bought a 51cm and typically smaller frames are 'female sizes' so why can't there be a wider saddle offered as standard, the stock saddle is completely awful and for a while I thought I'd bought completely the wrong bike - changed the saddle for a very ripped and raggy old saddle I had laying around and the bike became a different beast all together.

Disappointed by the lack of toe clips since they come as standard on 54+ frames above.

However the bike is wonderful
