Hi,

If you will go through Russia and other former soviet countries
I can help you with lots of informations and places to stay with russian cycle tourists, local bike shops where you can buy tubes or tyres etc.

If you need really good bike for your trip I can suggest you to build your bike yourself from various parts you choose
Then I can help you with quality titanium parts like frame,
front fork etc.
Feel free contact me titerra@yahoo.com

Good luck! Victor
