Go tubeless they said. It’ll be good they said.
28C Conti GP5000 TT’s.
UCI Illegal or bust.
I confirmed that the ENVE 5.6’s are clinchers so I ordered some 28C Conti GP5000 TT TR’s and 19g RideNow TPU tubes. I was determined not to make a mess with the conversion, but man, what a mess! Front wheel had a lot of sealant in it, and the rear wheel had hardly any, again confirming that you just don’t know how much sealant you have in there at any one time.
Surprisingly the GP5000 TT’s both came in at 239g. The ones on my SL8 weigh in at 248g and 247g so I took those off the SL8 and put them on the S5, and put these new lighter tyres on the SL8.
Whilst I had the rear ENVE off I took apart the rear hub to clean up some grease and I removed the dust cover too (I also did this on my ENVE 65 Foundation wheels on my Allez Sprint) and the hubs are now obnoxiously loud! I thought I’d weigh the wheels whilst I was at it too, and sadly they come in at a hefty 1590g.
The wheels specs on these ENVE 5.6’s is pretty weak; The front wheel is 54mm deep, rear is 63mm. External width is 28.75mm front and 28mm rear and internal width is 19mm.The 30C tyres that came on the bike blew out way past the rim (big time mushroom), and the 28C TT’s do too (but not by much), but hey they look awesome, and now they sound awesome too so I’m keeping them on, for now.
Now waiting on narrower 38cm bars, XMCS 155mm crankset, 1 by chainring, Direct mount hanger, Hylix seatpost (just restocked today TF for that!) and Ti bolt kit to replace all the bolts in and around the cockpit and headset.
