Happy with the communication of confirmation of product details I received from Sierra Bicycle Supply. The new '22 carbon Specialized Stumpjumper was even better looking in person than in the pics. The matte finish demands it be wrapped since everything leaves a mark on it. Overall, pleased with my purchase!
Needed to replace my batteries after shipping the bikes from Europe because the shipping was a pain in the butt! Sierra Bikes was recommended by Specialized U.S. and they performed wonderfully. Even held the batteries for me until I arrived at Denver! Built them into the bikes & went riding the next day! Thank you very much!!!
Work great
I’m really enjoying this monitor. Im using it in jiu-jitsu, and it’s great that I don’t need a watch or phone nearby to use it.
Here is how I am using it.
- Customizable displays for ...
- Heart Rate Sensor
- Garmin Pedal Power Meters
- Lights control
- Cadence Sensor
- Speed Sensor
- DOES NOT WORK WITH SAMSUNG WATCH 8 CLASSIC
- Records Route Creation but need to be careful with saving rides as not doing two rides back to back = lost
- does not come with a one hundred twenty page manual.But I was able to find a pdf file online
Can’t recommend SBS enough. Fantastic pricing, great communication, and prompt shipping.
I saw the feedback around certain items being out of stock… not sure why folks just don’t pick up the phone. I called to confirm availability. The team was polite and quickly confirmed the bike was on the floor. Quick ordered it, shipped and received. Packaged flawlessly.
Easy transaction and I would highly recommend working with them.
This is my do-it-all bike. It does fast XC, decent-sized chunk, and climbs like a mountain goat. The best part though is the service and sales process with Sierra Bicycle Supply. Those guys are the best!
We love the staff and store so much that we purchased our BMW motorcycles and Specialized bikes from this dealership.
Whether riding at 150 mph+ on your motorcycle or just 40 mph+ on your ebike, you'll be glad you bought them from this store
High Quality, at a Great Price. Most importantly, the boss is very happy about it. Just in time before Father's Day, so I could earn some credits.
It comes with Headset, cable plugs for Wireless settings, and the MRP Chainguide. (thou, I had to put a spacer to make it fits for the 52mm chainline...)
