I had a 303 which was essentially the same as the 305.
It’s a great frame and builds up into a nice bike with a 5″ fork – not light but not silly heavy.
The ride is great too – excellent for trail centre type riding. Not overly harsh on the bumps or all day riding.
Mine cracked/broke around the weld that joins the seat tube to the top tube gusset thingy but I’m 6’5″ and rode a 19″ (L) one with A LOT of seatpost out – Pace had said that it would be ok when I asked before I bought it.
No problems with Pace replacing it under warrantee so I was happy enough with that. I sold the replacement as I reckon that the same would have happened again ( I really needed them to make an XL size ). I’d certainly recommend one though for more average sized people.
