Tyre system investment strategy advice sought:
Setup per wheel:
Hutchinson Sector28 tubeless road tyre, UK LBS = £50
Stans NoTubes road valves = £6
Stans Notubes sealant = £22 for 1000ml = £1.50
Tesa 4289 tape (£10 for 60m on eBay UK, same as Stan's) = £0.83p
Total setup: £58.33
4 x Stans refills per year = £6
Assume 5,000k out of a Sector28 (YMMV) = £50
Total annual tubeless cost = £56
This versus buying a Conti GP 4 Seasons + Tour 28 tube - £40. Assuming similar wear rates and doing in 1 tube per year (reasonable I think, Conti's are great but not that great)
So, an extra £16 per year for the benefit of tubeless flat protection + (apparently) non-existent pinchflats + no roadside faffing in the cold/wet/snow/traffic/stares of grumpy peloton plus about 45g lighter overall.
Any reason not to go tubeless?
