It'll help

Always good to get your spelling right as it makes you look more respectable and also helps when people are searching on here or on eBay.
A lot of eBay sellers get the spelling wrong when the right name is often helpfully stuck onto the product by the manufacturer
It's quite a nice Cadex, but you'll probably have more interest asking for this post to be moved to the Road section here:
viewforum.php?f=37 and you can always put in a new one here for the Marin.
Good luck with the sales, always nice to see people saving these bikes from the dump!
