Thinvik Bottom Bracket, BSA 68-73mm English for 24mm Spindle Crank,Compatible with Shimano Crankset

For the price, I don't think this BB can be beat. Would I put it on a high end bike I ride hard on singletrack? No. But for the bike you're trying to upgrade from a square taper to 24mm spindle, it's perfect. Installs just like any other threaded BBs. The only knock is that it does not come with instructions, which may be an issue if someone has zero experience w/ BBs.

This was shipped and arrived very fast from the seller. I can’t comment on longevity, but the BB appears to be well made, threads are clean and precisely made, and it spins very smoothly and bearings feel very smooth by hand as well

Easy installation, fit and functionality are great for $15, no noise, looks great, mine came with the plastic spacers, luckily I had extra aluminum ones, I really dislike that they’re plastic spacers and center tube, but for the price, I guess you get what you get. Therefore I can’t complain, if you want aluminum, spend more. Fit my Ozark Trail M.2 perfectly. I used 2 spacers on NDS and none on the DS. Took about 15 minutes to install, make sure to purchase the 16 notch cup tool, it makes the install, adjusting and disassembly very easy!

I purchased this bottom bracket to replace the stock square tapered bottom bracket on my mountain bike. It fit perfectly and worked well with a hollow tech crankset I already have. I’ve ridden 20 miles or so on it and it is smooth and quiet.

Cheaply made

Good but not fit on my bike

Shipped fast- worked perfectly!!

Cheap but will work for awhile

Fit perfectly on my carbon fibre gravel bike. Standard BSA threads for this bike with Shimano 105 components. This BB is better than the original one. It included a crank sleeve (the original component did not). The bearings rolled smoother. And they fit the hollow tech crank perfectly. Would buy again but likely will not need to for many kms!

Buen empaquetado y sensación de calidad percibida pero no sé cuánto durarán los rodamientos porque está recién instalado

SHIMANOのBBが経年劣化の為 本製品に交換。バリやガタも無く回転も問題なし。性能は比較していないがBB自体、ベアリングとガワにスペーサが主な構成と理解したので性能を語れる類ではなさそう(好みの問題は捨て置き)。個人的には耐久性が第一で、SHIMANOが3年耐えたので本製品は如何に？。交換はソコソコ面倒で、該当部を外すと密閉部かつ泥水が出てくるので それなり耐候性は必要な箇所の様。蛇足だが部品も工具も安価なのでセルフ整備し易いほうかな。パーツクリーナーやグリスに養生道具エトセトラと付帯的なモノは当然必要だけど。たぶんチャリ屋に持ち込んだらトータル10,000円前後かな？ (自分がチャリ屋のオヤジなら、それくらい請求させろよ？と感じた)もちろんチャリ屋ならSHIMANOかそれ以上に高価なBBを付けるだろうし、利益も出さなきゃいけない。オヤジの苦労がよく理解できる部品の一つだった。

Es extensible y válido para varios anchos

Replace a ball bearing bottom bracket with this seal bottom bracket. Fits perfectly and is very smooth. Ease to install as long as all the threads are very clean in the bike. Installed on an older mountain bike.
