Merida One-Twenty 7.800 suspension bearings

I hunted all over the internet to find out the sizes of the pivot bearings in the frame on Shelley's bike. I did not have any luck finding any details for the 2015 model year.

The only solution was to take the bike apart and measure them.

Although I double checked and took measurements, if you look very closely at the seals, they include a part number.

New bikes

All the cycling, Shelley has been doing, has inspired me to go out riding myself. That has led to me getting a new bike.

It's the first full suspension bike I have had. So much nicer to ride on the terrain round us, than the hard tail, front suspension only, bike that I have had for the last 14 years.

Shelley has a Merida One-Twenty 7.800, 2015 model year.

I now have a Giant Stance 29er 2, 2020 model year.

I am very pleased with it. We did over 18 miles on Saturday, nearly all off-road. I kept up most of the way but I was struggling with the pace towards the end. A nice ride.

I made a couple of adjustments on Sunday. Most important was a new, more comfortable, saddle. That means more padding.

I shortened the handlebars, from the massive 780mm width down to 720mm.

I fitted a dropper post that my brother, Roy, and I serviced to get it working.
It's all setup ready to go.

Dropper Post
Having tried it for a while, I now know I need one with less than 100mm drop. The one fitted has 125mm drop and that makes the saddle way too tall for me.
