About this deal

Cervélo introduced the new BBright system on the R5ca, and while it offers some sound engineering advantages, other companies have been slow to adopt it Immediate Media

Italiani P, Boraschi D (2014) From monocytes to M1/M2 macrophages: phenotypical vs. functional differentiation. Front Immunol 5:514. https://doi.org/10.3389/fimmu.2014.00514 Crank compatibility is another BB386 EVO strongpoint. Despite the bulbous dimensions, the shell will accept most modern crankset fitments save for dedicated BB30/PF30 and BBRight designs.

Other names PF41 (Hope – refers to BB shell diameter), PF24 (Chris King – refers to spindle diameter) There are three current Hollowtech II road threaded BB designs (different model numbers of identical designs also exist).

Food Res Int 57:44–50. https://doi.org/10.1016/j.foodres.2014.01.010 BB30 and PF30 cranksets won’t fit frames with different BB shell standard, because their spindle will be too short. With the PressFit 30, they’re using the same technology with the larger bearings and the same technology with the bearings living inside the frame, but they’re utilizing the nylon to their advantage where you have a more realistic tolerance.”Cons: Heavier than press-fit systems; frame design limited by relatively small-diameter and narrow shell Crank designs that will fit: Standard 24mm external-type only. A GXP conversion kit is also available The granting of a best price is not combinable with other promotions (e.g. "free articles) from Bike-Discount. Cranksets with 30 mm wide spindles won’t fit into frames with BB86, or BB90 BBs, but with correct BB some can be made to fit into threaded frames. Compatibility Originally designed for BB86 cranksets and bearings. New integrated CeramicSpeed BB fits 30mm spindle cranks

Table of crankset standards and compatible BBs (all the cranksets are compatible with the BBs of the same standard, of course, the others needing a special adapter): Crankset standard Pros: Lighter weight; more resistant to axle twist; more heel clearance; larger-diameter shell and spindle; potential for narrower pedal stance width

Kaur IP, Chopra K, Saini A (2002) Probiotics: potential pharmaceutical applications. Eur J Pharm Sci 15(1):1–9. https://doi.org/10.1016/s0928-0987(01)00209-3 Our] Hollowgram SiSL2 crank with SpideRing weighs 484g. By comparison, Dura-Ace 9000 weighs around 678g [we recorded 637g in our review – ed]. In addition to weight, another BB30 advantage is stiffness. By increasing the spindle diameter, you increase its resistance to twisting, which is where the bulk of the deflection in a crankset comes from. Roughly 70% of total deflection measured at the pedal comes from axle twist.” If not, would the Chain Reaction Ultegra Groupset Builder with the "English 68mm" option fit the Dengfu FM098 frame with the "English BB" option (supposing this is actually a separate option from the "BB30" on the Dengfu FM098)?

Some very rough guide (what I often try with first) would be: Other notes Threaded shell can be made with better tolerances and can be replaced if it wears out. CeramicSpeed now offers a fully integrated bearing (akin to T47) that will fit 30mm spindles However Shimano advertise that SM-BBR60 & BB-R9100 use 'small ball bearings'. This is not necessarily a good thing, in that smaller bearings are weaker. However there are more of them. Still it would be reasonable to assume that the RS500 will be DIFFERENT in durability from the other two, but not necessarily worse.
