Here's my true winter warrior.It is a Isla cross frame made out good ole 531.Bought the frame of E-bay looking a bit worst for wear. A new powdercoat and a smattering of 105SC parts and this is what you have.The 14 gears have been faultless.The front friction shift has been superb.Have a Bonty almost built which will be shown soon,so might have to sell this machine. Best offers please P.M me.Hate to see her go! Thanx Max
