The Montra Rock 2.1 is an Excellent MTB as it has great suspension and comes standard with 26" Kenda Tyres. I've been using this bike for the past 6 Months and i cannot be happier. The only drawback i would say is the seat. It is extremely uncomfortable and i would suggest getting a cushion for the same . This bike also has Decent off-road capability and the suspension and tyres give decent support. All in all i would definitely recommend this bime to anyone who is looking to buy a MTB. Also, i forgot to mention that the bike's frame is made entirely from 6061 Aluminium and is very light considering this is a MTB.
