How much more positive than saying a 10 speed cassette will last 5,000 miles if you take care of it do you want? Parts availability doesn’t make much difference today if the 10 speed cassette lasts 3-4 years. Adding 1 gear does not make a cassette high tech and modern. Better? But if you really want the 11 speed and it would make you happier, why ask? It’s not like it’s a huge investment. I’d suspect the 11 speed isn’t readily available right now either. Parts are in short supply everywhere.
All 11 speed drive parts arrived within 2 day shipping. Not hard to get at all. Available anywhere. The 10 speed stuff is whats hard to get. Believe me. I tried.
As I originally wanted an "Ultimate T10+. None were available from my dealer, so I decided to see what I could do to make to make my Medeo T10+ a, Medeo T10+Ultimate. My Medeo, $3499 The Ultimate= $3999. What to do with the extra $500 I had already set aside for the Ultimate? Make my own. In my opinion it's what Gazelle should have included with the Ultimate.
1. More modern and robust drive-train.
2. Intuvia display instead of the Purian.
Upgrading the drive to 11 speed, all Shimano XT. (Cassette, Derailleur, shifters, cable & cable, including labor $307.75
Display: Intuvia retrofit kit= $134.95,(ships free)
Mount for Intuvia Display= $45
Sub=$487.50
$100 credit for original parts
So, For $387.50 I've turned my Medeo T10+ into a, Medeo T10+ Ultimate.
Only thing I'm missing is Red paint and a better light. Oh wait, I've still got $112.50 for a light upgrade! I'll live with the "petrol" paint I've got
I'm retired, have the money and time and I love doing this kind of thing. Will post pics soon.
