Sunrace Freewheel 8 Speed 13-34 Teeth

A couple minutes to install the new freewheel, work perfect, a couple day after I ordered this freewheel, product was delivered to my mailbox, very fast, shipping, works perfect, out riding again! Thank-You!

Awesome freewheel. Wanted to add some range and gears on my fat bike and the swap was perfect on my stock Mongoose Dolomite setup, perfect fit with no spacers or mods needed! Went from a 7 speed to a 8 speed and paired it with a whole new group set. I recommend this over the Shimano Megarange if the the shift from 1st to 2nd gear was way to drastic for your taste with the Shimano. Worked well for me.

I have recently done a mtb touring bike conversion with 8 speed shimano bar end shifters and made it work with the stock 7 speed, 14-34 freewheel. However there's a big leap from the second lowest to the 34 tooth sprocket. This sunrace eliminates that leap, gives you smooth shifting and eight speeds without having to upgrade to a new cassette hub wheel. Excellent quality with nice shiny zinc plated sprockets, I even decided to put a new kmc x.99 shiny silver chain to accompany this freewheel. Gives the bike that extra bling and functionality.

Good product for the money, but mine had horrible bearing noise in the freewheel. Ordered replacement and it is much better. Hopefully it doesn’t degrade over time, but the 1st was bad out of the box. Uploading a video of the bad one so you can hear it. Apparently not allowed to upload 2 videos so I can’t provide the 2nd good video...

Transformed my kid's 6 speed 20" mountain bike to an 8 speed. Needed to adjust spacing on the axle slightly for the chain to clear the chain stays in high gear. The chain stays are 'sprung' slightly (~3mm) but it fits and works well. Used the original SRAM 3.0 (readjust limit screws) derailleur with a new SRAM X.4 Right shifter (original was twist shift). 8 speed KMC chain X8.93. Quality of some of the machining was slightly below the original 6 speed Shimano, but acceptable. Having 8 speed is awesome and my boy can climb hills much more easily now.

This freewheel is junk. It's noisy, It wobbles and the bearings are loose. I took it apart and greased the ball bearings (they were dry) Helped for a few minutes. It does look good and it does shift ok but makes a horrible noise when free wheeling. I bought it because it was the only 8 speed freewheel I could find, Now I'm thinking of going to 7 speed so I can buy a Shimano or getting a new wheel and going with a cassette. Very disapointed in the quality of this product.

I was building up a loaner fat bike and was doing at least minor upgrades of the junk that came with the low end bike from the factory. When I upgraded the shifters to 8 speed I needed a new freewheel. There's not a lot of options anymore for 8sp freewheels so I'm glad Sunrace is keeping something out there on the market. It actually seems to be better quality than the name brand 7sp I replaced and has a much more useable gear range. It takes a shimano type freewheel tool and installed easily. It locks up right away when pedaling and doesn't wobble when freewheeling, what more can you ask for?

Put this on a Mongoose Dolomite, fat bike. This added an additional lower gear to the bottom end. Much appreciated for trail riding. It also makes the top gear a bit higher to. Screwed right on with a standard Shimano freehub tool. The stock derailer worked fine with the added gear, and there was enough room for the added sprocket, but the shifter needed changing to go from my old 7 speed to this 8. Quality seems fine.
