Fitting a saddle

[philinmerthyr]

I have changed the saddle on my bike but I can't get it 100% flat. When I put a spirit level in the seat the nose is very slightly pointing up. Will this cause me discomfort?

The adjustment on my Roubaix is a pain. The rear bold is hard to tighter. It is not an Allen key but a round nut that needs to be tightened by hand under the seat. Can someone advise me how best to adjust this.

It's worth checking that you didn't put the seatpost in the wrong way round - assuming it is a micro adjust type.

Hand tight the nut plus a bit more tight using a suitable spanner, until saddle moves only if you press hard on it.
Then put a couple of heavy books or similar on the saddle, spirit level on top, adjust level, firmly tighten nut.
This works for me.

Bike needs to be level for that to work.

Using a length of wood to check the seat is level is a great tip. Not looking too bad now. I'll ride the bike on Wednesday evening to check its comfortable.

Bike needs to be level first.

+1 - if the bike is not level the saddle won't be. Check that the surface the bike is standing on is level first.

To get the bike level I use a work stand and get the bike level by using a piece of 2"x4" wood touching the bottom of both wheels and with a spirit level on the top surface of the wood.

It's on the concrete base of my shed which should be flat. I think a ride on Wednesday will tell me all I need to know. If it feels flat and comfortable I'll be happy.

Spirit levels, books, planks of wood......too many perfectionists on here! ;-)

Put a level on your concrete base and look to see were the bubble is to the lines
bike on the base in the same place, level on the seat get the bubble in the same place as it was on the floor ?
or if you want to get technical spin a lazer level thats how the pro teams do it Trust me Iam a joiner !

First ride on the new saddle tonight. It was only 10 miles but he saddle was very comfortable. I'll have time for a long ride on Saturday to will test it fully then but it feels flat and the position is great.

I know a lot of builders, so I imagine your concrete base is not flat
