SKF BFR-600
Just arrived at TartyBikes is a range of great ISIS bottom brackets from Swedish bearing specialists SKF.
- Unlike other bottom brackets, the SKF models use taper roller bearings on the drive side, which have a load bearing capacity of TEN TIMES that of standard ball bearing units!
- The non drive side bearing is a standard SKF fully sealed unit, made from high quality steel.
- Full stainless steel construction with super-tough M12 axle means this bottom bracket will last and last... SKF have designed this model around a service life of 10 years!
- Each bottom bracket is sealed for life, and needs no further maintenance.
- Fits both 68 and 73mm shell bottom brackets, simply add the spacer for 68mm, or remove it if your frame has a 73mm shell (such as the Ashton Justice).
- Requires the XTR Bottom Bracket Tool to fit and remove.
- Available in 118mm and 128mm lengths.
- Weight: 382g
Please note that this bottom bracket does not come with crank bolts included, however these can be purchased here. (болты не идут в комплекте, бла бла бла)
Truvativ Gigapipe DH
- Following recommendations from various riders, we thought we'd get some of these super-tough BBs in stock!
- Double sealed cartridge bearings on both drive and non drive sides of the axle offer maximum durability and load bearing capabilities.
- Water/dirt seals to both sides of the bearing keep out the elements!
- Super strong M12 cromoly steel axle gives plenty of strength for trials usage.
- Aluminium cups save a little bit of weight where possible.
- Includes Truvativ's own cranks bolts with 8mm allen key head.
- Fits 68mm and 73mm BB shells and has a 128mm long axle (use the supplied spacer for 68mm shell use).
- Clears all models of freewheels, but may not fit with some setups using a bashring - please ask us if you are unsure.
- Weight: 358g plus crank bolts.
Так что я за гигапайп
)) Вес вполне возможно у SKF больше, платишь толька за мажорность.
У меня он уже больше 2-ух лет например.
