Best Companion
Used for 3 to 6 months
My experience with my Triban520 has been best so far. I do average 60k every weekends and 100k once in a month. They have been smooth and trouble-free. For the price you pay and the value which you get in form of groupsets, fork and alu body is a killer deal as compared to other bikes in the market.

My beauty
Used for 3 to 6 months
I have always been fascinated to bicycles from childhood. But the requirements of the professional life and desire for comfort made me opt for cars. Yet, the longing to go out on the roads with a bicycle on the one hand and the fear of getting out on an un-cycle-friendly road with speeding motorists on the other hand made me in a state of indecision for long. But when I saw ‘this beauty’ at Decathlon, I disregarded all my fears and bought it.
I believe that it is more of an attachment to such a beautiful piece of engineering than desire to ride it that made me go for it. But frankly, I have started waking up early and ‘riding on my beauty’ (please don’t have wild guesses!!) and feel really energised. Go for it, for it will bring smile on your face…
