Double chainring equipped entry-level 27" aluminium hardtail featuring a more upright and, therefore, more comfortable riding position than our more race-focused hardtails. The riding position puts less strain on the lower back and also improves the visibility of what lies ahead. A 100 mm suspension fork from Suntour and hydraulic disc brakes improve comfort and control even further.

Mountain biking is one of the most varied cycling disciplines and probably the most demanding when it comes to equipment. While full suspension bikes offer amazing riding characteristics, the classic hardtail remains one of the purest tools for the job. Our 27" wheel equipped BIG.NINE range comes in carbon and aluminium and features multiple geometry options. The carbon and LITE framed BIG.NINE, with its racing geometry, is an ideal companion on XC and marathon race tracks whilst the more relaxed geometry of the BIG.NINE TFS and SPEED offers a more comfortable, upright riding position.

Feels Like Sleeping on a Cloud — One of My Favorite Bedsure Products Yet
Color: Black, Size: King
I’ve had really good experiences with Bedsure products over time, so whenever I get the chance to try another one I usually do, and this mattress topper definitely did not disappoint. This one went on my mom’s king size bed and the difference was noticeable immediately. The topper has a soft, cloud-like feel while still giving enough support underneath so you don’t just sink straight through it. It added a much more comfortable layer to the mattress and made the bed feel cozy and inviting without being overly heavy or hot. I also appreciated how easy it was to put on. The deep pocket design fit securely over the king mattress without struggling to stretch the corners, and once it was on, it stayed in place well through the night. The material feels breathable and smooth, which is especially nice for warmer nights. My mom commented that she slept really well with it and woke up feeling more comfortable than usual, which honestly says a lot. Overall this feels like a high-quality mattress topper that makes a bed instantly more comfortable. Bedsure continues to be one of those brands I trust for soft bedding and reliable quality.

Not Worth the Price
Color: Black, Size: Queen
I expected more. The images are a bit misleading with the amount of fluff and thickness the product actually has. Despite following the instructions, it’s pretty flat. It had a funky chemically smell to it, so I sprayed with some Febreeze. Honestly in my opinion I don’t think it’s worth $60. I think if you want something similar, go to Marshals or TJ Maxx.

Makes my camp mattress so much better.
Color: Black, Size: Full
I'm in a small motorhome and this has helped my sleep quality a ton. I got rid of my big mattress because the 2 camp mattresses I have are smaller in size, but a bit dense than the mattress I had. Uncomfortable for anyone that sleeps on them for long periods and when I come from biking or hiking the pain was making it hard to sleep. These have improved my sleep quality immensely. It also, to my surprise fit well, the cushions are only a few inches. These are up to 18, but the edge is nearly a perfect fit at the start. The straps keep it from moving. The length and width using 2 of the bed rolls is nearly perfect. On mattress the deeper part of the pocket, would fit perfectly. The quality feels great, lightweight and washable, this is one of those items I wouldn't have likely ordered, but trying it is near priceless for my usage. Couldn't imagine how good it must be on a bed.

Works very well!
It is made of good quality and has definitely helped with my hot flashes at night. Love the color. Soft and light weight. Only thing is it tends to slide off here n there but its no big deal.

The best comforter I've ever had. Like being wrapped in clouds.
Color: Light Grey, Size: King (104''x90''), Color: Light Grey, Size: King (104''x90'')
I've been suffering for a long time with night sweats due to menopause and have been experiencing insomnia. Even in winter, I sleep with a fan on. I would wake up several times during the night, alternating between feeling cold from being uncovered and hot from being under the duvet. Well, after much research on Amazon, I decided on this product, and it was the best decision I've ever made. I have no words to describe the comfort, the softness of the fabric, and how cool it keeps me. It's thin, but it's cozy and doesn't slip on the bed. Tonight I wasn't fighting a battle in my bed.It really is exactly as described in the product description. I slept without feeling hot and didn't even turn on the fan (my house's heating system wasn't on). I highly recommend it, especially for women going through menopause. It's worth every penny. I think I'll even buy another one in a different color...
