Re: 26 inch wheels on a 700c frame?

Well...in cycling - as in many other things - the best answer is, it's possible, but is it worth it? For me, the answer is yes. I had a spare 51cm Pompino V4 frameset, a Sturmey Archer 3 speed hub with drum brakes, matching front hub and plenty of suitable 26" rims. We need to move substantial ...

Re: Non-standard spoke issues and purchase

Hi Geoff, If you have a problem getting Sapim Strong spokes I've got some in stock (also 2.3mm plain DT Swiss). Length doesn't matter as I have a Morizumi cutting and threading machine. Takes a few days from here in Spain to the UK. PS: The catsnapper name was dedicated to a favourite tiny, stray ca...

Re: Non-standard spoke issues and purchase

Hi Geoff, Justin at http://www.ebikes.ca have an online e-bike spoke calculator http://www.ebikes.ca/tools/spoke-calc.html that enables a wider range of calculations. It might look a bit too complex at first look, but it has been well thought out and works well. I've built many e-wheels using standa...

Re: Spreading a steel front fork - wisdom sought.

'Voilamart' is an Australian company (also in UK and Germany) supplying a range of goods including badged e-bike hubs and kits from 250W upwards. Judging by the weight you mentioned it's the 250W. I agree with the several commenters suggesting caution - you're doing a few firsts, along with many oth...

Re: Exzentriker bottom bracket....

The Dialled frame was designed for the traditional Phil eccentric and supplied with it. This is non-threaded and clamped externally with two bolts. The eccentric is then fitted with a standard threaded BB. The Philcentric TM is the unit similar to my Canadian one. I've considered buying the Philcent...

Re: Exzentriker bottom bracket....

We have a Dialled Bikes Love/Hate frame fitted with the Phil eccentric BB. It was built up as a knockabout single speed bike for family and visitors, so gets heavy use. I've seen some adverse comments, but once set up correctly ours is problem free and non-squeaky or creaky. Maybe not as discrete as...

Re: Exzentriker bottom bracket....

I've got a similar unit made by Forward Components in Canada. Works as Gattonero has described, with the same care when installing it. One additional comment is the limited adjustment - if you're unlucky you may need to use a half-link. I've used the unit on several bikes (alumInium and steel), with...

Re: Eccentric bb

Hi Belgiangoth, I have a low use Canadian made Forward Components EBB that works with many 68mm bottom bracket shells. It works with cranksets (Shimano) that are compatible with Hollowtech II bottom brackets. It's similar to the Exzentriker unit, well made, solid and quite easy to adjust although yo...

Re: Bottom bracket cup (right side) stuck - I need a few ideas...

Success at last! Thanks to all for your ideas. The suggestion from Brucey got me looking for some high tensile nuts and bolts in the store. Sure enough a 24mm A/F nut was an almost perfect fit. After locking on a bolt and using a large adjustable with a 1metre wrecking bar started it moving....... C...

Hi all, My wife had her trike stolen (locked, chained, in private garage!). The quickest solution to get her mobile again was to buy a Jorvik Chinese made trike, then replace the junk parts with decent ones. Everything went as planned until we came to the bottom bracket - despite the spec listing a ...

Re: What tool do I need to remove this freewheel?

The broken spoke is behind the cassette and there appear to be no way of getting a new one in there without removing the cassette. A useful but long forgotten product - the Z bend spoke. It lets you fit a new spoke without removing the cassette/freewheel. I hadn't seen one for years, but I was remi...

re tied and soldered; The absence of such noises may well be interpreted as, or ascribed to 'increased stiffness'.
