renn gravel bike Sandman 6The Sandman 6 elevates gravel performance with Shimano's GRX600 groupseta refined 22 speed (211) drivetrain that delivers wider gear range and more precise shifting than entry level systems.

The Sandman 6 elevates gravel performance with Shimano's GRX600 groupset—a refined 22-speed (2×11) drivetrain that delivers wider gear range and more precise shifting than entry-level systems. The GRX RD-RX810 rear derailleur with its 11-34T cassette provides smooth transitions across technical climbs and fast descents. This is the groupset where Shimano's gravel-specific engineering becomes most apparent, with improved ergonomics and clutch technology that keeps your chain secure on the roughest surfaces.

Built on the same TORAY T800 carbon frame as the Sandman 4, the Sandman 6 maintains the 9.8kg complete weight while upgrading the components that enhance ride quality and longevity. The GRX600 hydraulic disc brakes offer more consistent modulation and require less frequent maintenance than the 400-series. The upgraded Shimano 11-speed chain runs quieter and lasts longer under load. These refinements add up over hundreds of kilometers—less time adjusting your bike, more time riding it.

We've equipped the Sandman 6 with RINOS carbon components throughout—handlebar, seat post, and fork—creating a cohesive system that dampens vibration without sacrificing responsiveness. The aluminum headset provides a reliable interface between these carbon elements. The wider 38mm RINOS rims paired with Novatec 28H hubs create a wheelset that accelerates quickly yet remains stable when loaded with bikepacking gear. Every component choice reflects our focus on building a gravel bike that performs whether you're racing, touring, or simply exploring.

Available in four distinctive colorways and five frame sizes spanning 150 cm to over 200 cm rider heights, the Sandman 6 accommodates a wide range of riders. The bike's geometry balances stability with agility—confident on technical descents, responsive when navigating tight singletrack. Whether you're tackling multi-day bikepacking routes, competing in gravel events, training on mixed terrain, or seeking a capable all-road bike, the Sandman 6 delivers premium performance without the premium price tag. Manufactured in the EU to exacting standards, this bike is built for riders who demand more from their equipment.

FANTASTIC PAD HOLDER
Size: 28'' X 34'', Size: 28'' X 34''
Amazon Basics Dog Training Pad Holder 28X34. I'll start out by saying I wasn't too sure about it, when I got it. It is awkward to put the pads in by yourself if your short as on each end the sides have to come up together and it’s big, however, I've done it five times alone now and it’s doable. There was no smell, it arrived in perfect condition. My husband was home and we set it up together, I walked into the bathroom to get a soiled pad I had keep to put on it for her to know what to do came back and she had already used it and she’s only four months old. I love it love it love it, it’s not too big, but it’s her home too, and we have it in the living room where we spend a lot of time as we’re retired. When she gets a little older, we will probably move it to another room, but for now it’s staying there. After she urinates, it goes down to a very pale yellow color I have been able to use one pad for all day, however, she does have a pad in a under bed tote in our master bathroom. We’ve had a few guests over and if she hadn’t used it they didn’t even know what it was. I highly recommend it. I have been using pads in an under the bed tote for over 10 years and this is a welcome audition. You won’t be sorry if you have little ones that go in the house.

Very easy to use and clean
Size: 22'' X 22''
Saved my pad training with my puppy. It's firm and easy to clean. It holds the pads well for the most part, but sometimes my dog gets a little crazy and it comes out, but I don't think it could be better. Still give a 5-star!

Don’t buy
Size: 28'' X 34''
Mine arrived broken and scratched I think I received one that someone had returned. It also doesn’t hold pads that well my 4 lb teacup Yorkie is able to pull the pad off of the pad holder without even ripping the pad.

Excellent!
Size: 22'' X 22''
Highly recommend this pad holder. Does an excellent job keeping the pad secure and in place. No more shredded pads since. Bonus: no leaks on the floor. It’s so practical and so helpful.
