Jairaj you know one of the [many] awesome things about a pentax dslr is that you can fit loads of lenses [on k mount] with no adapter and they will all be stabilized because it’s in body. Therefore you have loads of glass to choose from.
You might be able to find yourself a nice legacy uwa on ebay or a forum.
Also take a look at the samyang 10/14/16mm lenses.
Perhaps should also consider the pentax da 15mm.
Pentax really is one of the most underated products/brands out there.
I guess there’s a realisation that if I was to enter an event. The difference between a bit of a do-it-all ~11kg bike and a more race orientated ~7.5kg bike might be quite noticeable.
Power is an important factor IMO. With my last road bike (which was pretty heavy), I was only just about able to stop safely going down a steep hill before a road junction. I also had to scrub speed off for most of the descent, so I found myself braking all the way almost 😆 . That was tektro long drops.
