My wife picked her Tero 5.0 up today and we took it for a 16 mile mixed terrain ride. I won't say she prefers it over her Vado SL 5.0 EQ yet, but she does enjoy the POWER! I had some Vittoria Mezcal XC Trail tyres installed at the shop, tubeless, which shaved close to a kilogram off the bike. I run these tyres on my Levo SL; they work well for the terrain that we ride. I am looking into a lighter weight fork, as the stock one supposedly weighs 2313 grams. Some are available in the 1300 to 1400 gram range, which would be a substantial weight saving.
My goal is to get the bike to 40 lbs without the battery so I don't over-stress the Kuat Sherpa rack that we use. The battery weighs 8 lbs 7 oz on my kitchen scale. The Sherpa is rated at 2x bikes 40 lbs each maximum. My Levo SL is 39.25 lbs.
As I am able to get some saddle time on the bike I will report back with some impressions. We are going on an off-road trail ride tomorrow, probably in Wilder Ranch State Park north of Santa Cruz. This will be a great ride for her as she has done it a number of times on her Vado SL. I have ridden this on my Creo SL, and it is a fun ride, but very harsh on the Creo and Vado. It will be good for her to be on her Tero and me on the Levo Sl. Hopefully I can keep up with her!!
By the way, Specialized are supposedly working on a hard-wired light package for the 5.0; I have asked the LBS to inform me when they arrive. My wife likes the always-on lights on her Vado SL 5.0 EQ.
