I bought a Planet-X titanium bike for my 40th after saving £25 per month in a “Friendly Society” account for 10 years.
The actual frame was made by Lynsky (original founders of Litespeed) and it had a 9 speed Dura Ace groupset – not bad for £2k.
It is great to ride but, as others have said, developments in the interim have made it seem a little old fashioned.
It has caliper brakes, which work fine but I prefer the hydraulic disks I have on my other road bike, and is limited to 25mm tyres which feel a bit skinny for our pot holed roads.The Dura Ace groupset has a 50/34 chainset and can cope with an 11-28 cassette which lacks the low gears I have on my other bike (34 cassette).
All that means I don’t ride it as much as I thought I would although my riding has also changed over time. I now do more long, hilly audax rides where lower gears, puncture resistant and comfortable tyres (i.e. bigger) and the ability to stop quickly are now more important.
If you want titanium then go for it but think long and hard about what riding you plan to do.
