New bike day, Mosaic GT-1 45 - 1st century ride

I ordered a Mosaic GT-1 45 a couple months ago and it came in Friday, just in time for my first century ride on Saturday. My prior longest ride was 82 miles.

It was a bit of trial by fire as to whether the fit would be perfect as I’m always tweaking with something on my diverge.

The bike was ordered through a local shop and had an initial fit and custom geometry based on my body measurements on a retul fit setup. When I had the post build fit Friday, it was phenomenal. We made a couple very small tweaks (basically just lowering the seat a hair) but perfect otherwise. I had hip surgery for a labral tear and impingement last year, and will likely need the other fixed eventually. I also completely tore my left hamstring (conjoined tendon) 2 years ago and opted not to fix it based on the evaluation from one of the best hip/hamstring specialists. I have garmin power pedals on my diverge and despite the left side history, my power balance is usually still 49/51 or 50/50.

Saturdays century ride could not have gone better. I often use clip on aero bars and while I got them for the Mosaic, I left them off. The smoothness of the titanium, carbon wheels, and general high end components is a night and day difference from my diverge sport carbon. Although I went from carbon to titanium, the new bike is about 4 lbs lighter. It was a charity ride with some breaks, but for 105 miles my moving time of 5:08 and NP of 198 watts. The ride had 500+ riders and I spent the first half with the front small group and finished up around the 2nd group. This felt great considering I was the only one on a fat tired gravel bike.

While my muscles were fully taxed during and after the ride, all my joints (hips and knees) and contact points felt better than I could have imagined.

The build:
Reserve 40/44 GR wheels with 47mm pathfinder pros (I have clearance that I could run a 2.1 thunder Burt up front)
SRAM Red XPLR 13 spd, 40T chainring w/ Power
Shimano XTR Pedals
Enve SES Aero In Route handlebars (37 cm)
Paint to match Enve stem, seat post, and Silca frame pump

I was hesitant to paint the titanium, but after seeing the paint in person I’m completely thrilled. I started my career as a welder and although I stopped welding for work 12ish years ago, it’s still a huge part of what I do. After welding I became a weld inspector, quality manager, etc., with a lot of inspection certifications and a degree in welding technology. The fascination and nod to welding is what steered me towards a titanium build.

And for the bike porn…

beautiful bike! if i ever replace my crux, i want one of these.

i thought tire clearance maxed at 45mm.

It’s rated for 45 since ISO standards require 6mm clearance. My 47 pathfinders measure 48mm and I have 4mm clearance in the rear and 7-8mm at the fork. The fork is an ENVE gravel fork rated at 50mm.

One thing I didn’t mention is that this was also my first time riding a 1x, and I was unsure how it’d feel gear spacing wise compared to the 2x on my diverge. I chose the 40T front chain ring so on flat sections (I live in Texas) I’d have tighter gear spacing. During Saturday’s ride, the gear spacing felt absolutely perfect. My fastest 5 mile split I averaged 29.3 mph in the front group and I still had 1-2 gears left. I may get a larger chain ring down the road if I get a set of road wheels particularly, but I’ll see how it works out.

Google is telling me that the app was shut down (which was used to submit bikes). Not sure if there’s a new method - I’ll do some poking around. Thanks!

This is a seriously nice bike, congrratulations.

1x13 XPLR gearing seems perfect for most riding, including road rides. (The first 11 gears are identical to SRAM’s 10–36 cassette, so the gear spacing is tight. Only for the last 3 gears do you have wider spacing.) If I had hills around where I live now :sob:, I would seriously contemplate getting 1x13 XPLR as an upgrade down the line.

Happy New Bike Day! :partying_face:

That’s a nice bike. I really like what Mosaic is doing in the industry right now.

I’m all in on metal bikes myself! :factory_worker:

Love that fade!!! Is that an R-Series? That chain stay looks impressively short!

RT-1d “thiccroad” fits a 34mm, rides like a road bike.
