I have another question for the experienced.
The Sedona ST has a single wall 36 spoke wheel while the Sedona has a double wall 32 spoke wheel. Which will be the stronger of the two wheels?
The double wall rim.
welcome to bike forums szerek and hope you're not too confused with all the replies if it was me and had to spend 400 quid on a bike i would probably go for something second hand. but thats because i know what i'm looking at- well i think i do at least i'd try a few bike shops and find one where you think you can trust them. don't be sucked in by the department store style bike shops with the huge selections but clueless staff, try a small family owned bike shop where they will give you the time of day. and most importantly is to test ride any bike you're thinking of buying. fit is more important than anything!!
wheels are very important and they are easily got second hand and dirt cheap. just look around the second hand pages
