1st upgrade, where will it end
Discussion
Have not been please with the braking on my Specialized Allez since day one, either the brakes are crap, or the pads a piss poor.
So went looking at pads, not that cheap are they for the good ones.......wait, whats this? Shimano 105 5800 Road Brake Calliper £20.99 on CRC - my 10% British cycling discount = £18.89 result.
arrived yesterday, was easy to fit and set up.

The old POS

Tool kit bought by parent 2 Christmas's ago

went for a short ride, holy moly this is way more powerful, this is not just down to pads, I can actually do an emergency stop.
105 for the back next pay day, then who knows what's next

You are at the same place most cyclists can remember being at... the top of a very long, very slippery and very steep in places slope! Upgrades never end!So went looking at pads, not that cheap are they for the good ones.......wait, whats this?

Enjoy the ride
When I started out in 2010, I never really had any plans to upgrade any items on the bike, then I rode my mates ultegra equipped bike and it was the brakes that left a lasting impression and thats when I decided to upgrade the brakes on my bike.
Going quick is great, but lets face it, stopping is also very useful and my Sora brakes were crap! I've still got them somewhere, but god knows if I will ever fit them to a bike again.

What makes the caliper better than the old one?
Pads have different compounds which I appreciate has a big effect on braking, but I cannot understand how a leverage based system can be any better.
Any experts mind explaining to a simpleton?

Like the OP, I replaced the cheap calipers my bike came with and the improvement was very marked.

and I cleaned the rim to with a kitchen sponge with the green abrasive stuff and then wiped the rims with IPA.

Not an expert, but to me, when I upgraded my calipers, they felt much stiffer. On the old Tektro monstrosities it felt like if you really squeezed the lever, the caliper arms would flex, rather than applying extra braking force. It felt like a stretchy cable, but with the same cable, the Ultegra calipers are worlds better.Pads have different compounds which I appreciate has a big effect on braking, but I cannot understand how a leverage based system can be any better.
