I’ve recently purchased a used 2011 Trek Speed Concept 7.5, at a bargain price, which I love. The groupset is 9-speed Ultegra, and needs updating - it’s very worn. I’m thinking of changing it to 11 speed Campy, to match my Bianchi road bike and make my wheels interchangeable.
Question is, is it worth throwing money at the Trek (about £300 in total for a used upgrade) or go for a Boardman Air TT 9.0, which I can get new (£100 per month) from the cycle-to-work scheme with my job.
Upgrade the Trek or get the Boardman - what would you do?
(I’ve posted on Slowtwitch too, just to get as many thoughts as possible)
