Well after 5 happy years of riding my cherished Siena (picture shown in members bikes 2nd one), the headtube has cracked across the weld and through 1 inch of the downtube.

I am told it's a reoccurring problem on the integrated headset models hence recent models have external headsets making the bike stronger!
So I drove 200 miles to my specialist dealer on the South Coast who are sending it back to the USA via Bristol for a replacement headtube under the Lifetime warranty plus a new external headset.
The job is likely to take 3/4 months due to a factory full of similar complaints (long queue), with shareholders wanting a cheap solution to the problem.
Watch this space as I will tell you how things go over the busiest months of my cycling calendar, with no wheels and an extending waistline !!!!

Now August is here and the bike frame repair has only just been started I'm not holding my breath but I am waiting patiently!
Warranty people have left Litespeed in USA and UK concessionaire's have been ditched!
