Fixed my spongy brakes

I bought a new Esker Elkat from Jenson in early 2021, but it was a vendor-specific build. Came with SLX 2 piston brakes in 180/160. It was always a bit spongy and I had to really clamp down to get any force out of them. All research just said yeah, the 2-piston SLXs are kinda spongy. So I purchased 203/180 set of XT rotors and some adapters, installed them, and while still kinda spongy, they now stop with authority. Love em

Fast service and exactly what I was looking for!

I was very pleased to find a much needed, and hard to find, XT brake rotor on Thunder Mountain Bike's website recently. The price was very reasonable and shipping was quick and smooth. I am very happy with the transaction and highly recommend Thunder Mountain Bikes! Thank you for having one of the only 160 XT rotors I could find anywhere online!
