I have a T1 and it’s ace, but I got mine for a good price. Only complaint is they chip pretty darn easy.
Keep your eyes peeled on gumtree and the 'bay for stray frames that need a home, and see what’s going round at your club and velodrome. A few of my friends have picked up BT cyclones for around a grand from good souls down at ours. Personally, I think it’s important not to get too engrossed in the stiffness, handling, performance side of things. Ride what you like the look of and you’d be happy to take down to the track and race, that fits your price range, and does the job.
If you want to buy off the rack I’ve got an avanti pista pro that came with mavic ellipses and omnium cranks all for 1500. Not much to upgrade although I wouldn’t bother with those felts that come with the 3T sphinx bars = garbage IMO
I have my doubts about those planet x frames. People get excited by carbon and when they see how cheap it can be had for they jump at it. I have no experience with planet x frames though, I just assume you get what you pay for.
As you get older, you’ll work out that appearance is pretty low down the list when looking for new bikes or anything else. You could have the prettiest bike in the world, but if you can’t ride it cos it’s uncomfortable what’s the point? Same as those fancy designer couches that look all awesome: some of those are the most uncomfortable motherfuckers I’ve ever had the displeasure of sitting on.
