First up, let’s look into a question that always comes up in relation to BB30—PF30 ARE BB30 and PF30 the SAME? I’d fit a stem 10-15mm longer if it were mine; it would still be short enough to keep a tight rein on the steering. The TRAD UK Top Management Team have shown commitment to satisfying all applicable requirements and compliance with customer, regulatory and statutory requirements, with industry codes of practice and relevant product standards (BS and EN). We also commit to continually improve our Quality Management System for sustained customer satisfaction and to continually meet the requirements of all interested parties. To date there are so few confirmed dates of manufacture or sale to be able to date any other frames from this period. The known numbers listed below indicate how difficult it is to attempt to construct a number dating pattern.

Cons: Metal-on-metal interfaces can be prone to creaking; requires a separate bearing puller and press for service; requires high manufacturing tolerances; bearing seats can’t easily be faced post-manufacturing; not all BB30 cranks will fitCompatibility Originally designed for 24mm spindles, but some BBs that fit a 30mm spindle are available Crank designs that will fit: BB30, BB386 EVO, standard 24mm external-type, Specialized OSBB, BBRight. Can be adapted to almost any standard with suitable adapters.

Pros: Stiffer than BB/PF30, in theory, without impacting other attributes; good crank compatibility, cheaper to manufacture than threaded or BB30 Another former employee, Norman Penstone, who worked for the company between 1957 and 1961, said that the shop in Seven Sisters Road was only a retail outlet and that the frames were made in Camden Passage, Islington, behind the main shop at 362-3 Upper Street, Angel. He lists the staff as:- Shop Owners If for some reason the threads are really tough and need a thorough cut (could be that tapping was never done on the original install), you may need to apply oil several times. Scott US marketing and PR director Adrian Montgomery touts similar reasons for his company choosing BB86/92 over other standards:From the outset, Cervélo introduced BBRight as an open standard that anyone could jump onto. While it seems to make good engineering sense, however, other bike companies have been slow to come on board. Other notes Similar asymmetric concept as Cannondale Ai, but the shell is wider BBRight (Press Fit) When squeezing the budget to build a bike to a price, tyres are usually one of the first casualties. Not here. Both bikes use decent all-round tyres from Maxxis: Ardents front and rear for the Voodoo; Ardent front and a faster-rolling Crossmark II rear for the Whyte.

Pros: Vast crankset compatibility, open standard, threaded design easy to service and prevent from creaking, same dimensions as PF30 But compare this to PF30’s 46mm BB shell diameter and you’ve, theoretically, got a a less-then-optimal setup, a theory which has been born out in practice. Every case is unique, despite commonalities, and you need to follow the road where it leads in relation to your unique setup. Other notes OSBB for Specialized Road bikes appears to just be BB30. An older Pressfit 61x46mm BB appears to be obsolete OSBB (Mountain) Crank designs that will fit: Standard 24mm external type (Shimano Hollowtech II, SRAM GXP, Campagnolo Ultratorque and Powertorque, FSA MegaExo, Race Face X-Type, etc), square taper, ISIS, BB386EVO, BB392EVO many others. Crucially external cups that fit 30mm spindles do exist.

He remembers the two large double-fronted shop windows in Upper Street with the entrance through the left-hand doorway. As you entered the shop the access to the workshop was in front of you. Frames were displayed in the right-hand windows, with accessories and clothing on the left-hand side. The shop was dark inside with brown paint and a long wooden counter covered with fawn lino that extended the full length of the two shops. Inside the shop a range of complete bikes were available which included roadster and touring models from other well-known makers such as Rudge. A wide range of specialist fittings were available from makers such as GB and Airlite. The Road Ultra was Reynolds 531 Butted Tubing with Ekla cast lugs, Campagnolo ends and Campag head and BB fittings. It had an exclusive reinforced fork crown and head lugs and seat-stay bridge.
