Tyres
You have all probably heard this before but last night I fitted two new conti 4000s tyres onto my stead with ultegra rims. I found it immpossible to get the tyres over the rims without using a lever, this meant having to use three tubes after pinching one. On my previous bike with shimano 600 rims I had no problems getting tyres on. Question is : does anyone have any tips or tricks as I now dread the thought of having to fix a flat out on the road (Thumbs are not 100% with arthritis)

Seems to vary with the make and tyre. Those Bikes for Refugees get, mountain bikes and 27 x 1 1/4, I can do by hand nearly all. My own road bike, need to use tyre levers.
I remember a time when nearly all bikes, you needed tyre levers.
Then mountian bikes came in with softer bead tyres, and you could usually do those by hand.

Maybe this might help:
I assume that when you changed over the tyres it was done cold. ie the new contis were straight out of the pack. Maybe next time try and let the new tyres sit in the sun for a couple of hours to warm them up (probably impossible given the weather for the past few days). This will make them softer and hopefully make them stretch them a little making them easier to get on.
When you do get a puncture when out riding (i say when cause it WILL happen at some stage) the tyre should be easier to get off as the tyre has had a chance to "warm" up. This theory is exactly the same as when V8 supercars (or any race car) first head out onto the track - you see the cars zig zagging all over the road, this is done to get as much heat into cold tyres as quickly as possible and to get the tyres up to running temp. The principle is the same for our skinny tyres. :-)

Thanks for the feedback and suggestions will see what happens next time a tyre is taken off.

Keith,
It may pay to ask Gary about this. He is usually full of helpful advice on just about anything bicycle related.

I highly recommend a Kool Stop Tyre Jack. Ive not come across a new tyre yet that has defeated this nifty tool.
Had a hell of a time getting Vittoria Evo Corsa's onto my Zipp 101s. After wrangling for hours I looked on the net and came across the Kool Stop Jack. I picked one up and my new Evo's were suddenly on in a matter of seconds. Being using it ever since...
It's a pretty light tool, about the size of a pocket pump so you could feasibly take it on rides if you're that worried. But by the time I got a flat with the Zipp/Evo's everything had well loosened up for an easy fix.

They are folding. Took them off again today and tried the talc treatment as sujjested here, while I still needed the lever for the last section it all went a lot easier. Also thanks Beckster I will look that one up

if you need to use a lever, don't let it seat the tyre for you, only use it to lift the tyre up to the rim wall and slide it on by hand as if you weren't using a lever. Some of these tyres seem to have quite a tight tolerance. Has anyone tried cutting the flashing off the beads?

I watched a LBS mechanic struggle to fit a Rubino on my Alex Da22 rim recently when i had the bike in for servicing.In the end he opted for a Basic rubino & not a rubino pro
