Re: Replace 27.5 rims with 700

There is variation in dimensions between batches of rims, and its possible that Sputniks suffer from being cheap rims. that is my impression too but I have (less often perhaps) also seen variations in more expensive rims... (My recollection is that the process is...extrusion...drilling and fitting ...

Re: Identify this frame - next Resto

it looks like about 25". I wouldn't worry much about that; raleighs of that period had very short to top tubes in the larger sizes; I worked out that the reach didn't increase more than 10mm between a 21.5 and 25.5" frame in one Raleigh model. So even if you have the saddle set very low it...

Re: 20" aluminium mudguards

If I have one complaint about the originals (other than the front crack of course) is that the rear one has never followed the curve of the rear wheel properly. In order to get it correct, it needs another stay half way between the other two to pull it in. It's as if the radius of the mudguard is w...

Re: Should I convert to a Rohloff hub - costs vs benefits ?

I like IGHs a lot but a) I wouldn't look to use a rohloff primarily for local journeys; there are probably cheaper alternatives for that (less nickable and will work as well in most cases) and b) I wouldn't factor the IGH into any calculations regarding whether you do or don't need a car. FWIW if yo...

Re: Dual purpose SPD shoes - fitting cleats

IIRC the Sidi adaptors are called 'N14' adaptors. I think they will fit any show with a similar curvature to the sole and a three-bolt mounting. Goodness knows where you get them from these days though.

Re: Identify this frame - next Resto

26.8mm does not suggest a record ace or 531DB tubing to me. PG tubing (maybe 501?) or perhaps something more heavy duty sounds quite likely.

Re: Dual purpose SPD shoes - fitting cleats

I dunno how those blanking plates come out exactly but at the least you will need - threaded metal plate inserts in the sole (between the insole and the sole) to take the SPD screws - 'pontoon' style SPD adaptors. (without these the cleat will not be flush with any part of the sole and there won't b...

Re: Handlebar Tape

the 'new' tape in the OPs upper photo is also wound bottom to top. You can tell this is the case because the logo on the bar tape is always the same distance from one edge of the bar tape only. It would be impossible to wind the top section top to bottom and have the tape looking like that.

Re: Replace 27.5 rims with 700

I've kept quiet about exactly what rims to buy because most of the ones that I know will be a loose fit are either too skinny for those tyres or are obsolete. I agree about sputniks BTW, except I would also add that they vary; some are worse than others. FWIW any rim with a shallow, sloping rim well...

Re: Handlebar Tape

I agree the top of the bars in the first photo is taped backwards. The open edge of the tape is pointing towards the rider.... In the first photo it is wound from the bottom to the top, and it has worn through because it is soft tape, not because it has moved or rucked up. Gloves may have helped it...

Re: Identify this frame - next Resto

this is another record ace from the mid 1980s; (1985?) https://i.ytimg.com/vi/P3zH4X70PF8/maxresdefault.jpg not quite the same colour scheme as the other one. Again the frame looks very similar to yours. [edit; neither of the record aces that look similar have a pump peg on the back of the head tube...

Re: Identify this frame - next Resto

one thing you can be fairly certain of is that it isn't a dyna tech frame; they were glued together, (whereas yours is brazed) in the main triangle. The frame number may contain a date. Apart from that you have clues such as -styles of lug, dropout, fork crown etc (but the fork may have been replace...
