Back in my rowing days blisters and rawness of the hands was not uncommon so we would use methylated spirits to harden them up - perhaps you could try this on yer bum :smile:
Seriously though I think it might be something to do with weight bearing, no doubt you are over weight (forgive me if I am wrong) and also in a position on the bike that does not share the load. So before buying yet another saddle fiddle with saddle height/tilt/ fore and aft. Take the spanner out with you and adjust as you go.

Can you post a picture of the bike taken from the side and one of you in your normal riding position, also from the side?

You cheeky bas..... yeah I am overweight.

Got home too late tonight, If the suns out for me, I'll try tomorrow night.

I was going to have a go at repositioning my seat tonight, but for love nor money, I can't find my allen keys.

I did also take a a side on picture of me on the bike, but I don't know what you expect to see besides my fat ass.

You could try raising the saddle a little, hard to be sure from the angle, I think you want your leg just about fully extended when your heel is on the pedal at its lowest position.. or thereabouts for starters. I'd also try moving the saddle back on the rails, that'll change your reach, may alleviate the pressure. Maybe a wider saddle with more padding would help, those slim narrow ones don't work well for me I've discovered.. Not sure of wheel/tyre size on Carreras but a wider tyre, if it can be fitted, would give a softer ride, too.

I like my saddle high, when I stop I can just about put my toe on the ground
and when I stop for lights ect I would slide off the saddle completely
It was once said on the web, but I can't remember who by “the saddle is not to sit on, but to stabilise you while you pedal”

All together now: saddle is too low!!! ^_^
Seems to me the handlebars are too near you as well, but how this could cause a sore bottom I don't know.
It *might* be the angle, but the whole bike looks too small to me. How tall are you @DEL 707 and can you find the bike's frame size?(usually on a sticker on the seat tube)

I'm 5' 10", I've had a look at the bike, all I can see is under the saddle 22nm.
I'm pretty sure when I bought the bike, it was the biggest frame they did for the Carrera Crossfire 1.

Went and got myself some new Allen keys this morning, I'll have a play around with the seat tomorrow, raise it up and move it back.

Readjusted my seat yesterday, up, further back and sloped it slightly forward.
Not sure if it's better or not, I'm going to have a longer cycle tomorrow to find out, but god damn the back of my theighs are killing me today for some reason, right in the middle, not sure if that's a good or a bad thing.

You need the saddle flat or slightly tilted back (only slightly :eek:) or you will end up sliding forward on it.
Basic set up should be
  • Leg straight when your heel is on the pedal at the bottom of its stroke.
  • The 'nose' of the saddle should be set so that the forearm/hand and to the 2nd knuckle will fit in between it and the back of the stem (this sounds complex but isn't, just form a 'Japanese throat punch' fist (you know that one from the 'Kung-fu' films) and stick yer elbow on the front of the saddle, as long as the 2nd knuckle misses the stem then you are about right)
After that it's down to preference and changing bits on the bike (which is where it starts to get expensive)
