Re: Friction Shifters

Dearer than a bit of heat-shrink, I went the Jtek route to run a MTB derailleur like yours off road downtube levers. A haul on that right-hand lever is as big a change of gear as dropping to the smaller front chain ring.

How are you mounting your levers - do you have bosses?

From a current project. He’d used p clips on the forks and stays, looked ok. Damn picture has come out upside down on the preview.

Re: 40T Cassette On A Road Bike

I went the Jtech route on my gravel bike build and have an MTB rear mech and cassette running off friction downtube levers.

Re: exal LX17 rims

My last build was a rear in this model and I remember pondering the same thing - the holes look like they alternate, but I decided in the end they didn’t and went ahead and built. Using the measurements on the EDD calculator, I wondered whether 2mm smaller might have been better.

Post script - tool idea for seized adjustable cup - cup and cone BB

£3.30 watch maker’s tool
£3.30 watch maker’s tool
It seems we’re left to get these off with pin spanners that only engage two pins.

I liked this tool because it it’s the right size, it would engage 3 rather than the normal 2 of the holes. But I doubt it’s robust enough for problem cups like this.
know thy enemy!
know thy enemy!
So I’d get a nut roughly the size of the cup and look to make 6 holes to correspond with those on the b/b cup with a view to firmly seating these pins - three might be adequate, six would be better. Clamp the whole thing down, nut in the vice and turn…

Riding the world bike shortage

It grinds my gears hearing that there are people wanting to buy a (new) bike and, I hope, get into cycling, but are being thwarted by patchy availability - see web link below. My own “N” is into double figures, and that’s to say nothing of the 531 framesets in varying states of repair. I’ve given away a couple of bikes and frames to local rescue places.

There’s still loads to be had on Ebay :

https://www.ebay.co.uk/itm/224510137108 - Raleigh Royal, spruce, £625 and ready to ride away today (NB pedals)

https://www.ebay.co.uk/itm/164943409915 - a decrepit £86 Raleigh Record Ace - looks basically rideable with some chain lube and the tyres mended.

I reckon I could do quite a lot on the Record Ace for a parts budget of £114 to make it a round £200 - and here’s the thing: with all the parts to hand, I could do this in an afternoon, and it would be my pleasure too. That’s the bit that grinds my gears!

new cables, authentic brown outers, new hoods and tape would probably benefit it, probably a new chain, subject to the below.

The biggest issue with this vintage is always what to do about the gears and the rear wheel. One thing I’ve not attempted myself is upgrading an existing rear wheel to a wider ratio 8 or 9 speed freewheel + ?new rear mech? (but should be able to go up to 30t), chain, and I assume a bit of widening of the rear dropouts. (I tend to just do new wheels with a 10s cassette and spring to 130mm.)

True up the wheels if they need it, regrease, service or even replace the b/b and headset.

That worldwide bike shortage in full:

:D :) :)
Although some way short of demonisation, none of the groups you mention could be described as “proper cyclists” in our little Velomati way, could they. :D

(When you say “like football” I assume you’re referring to those who, for the times it’s on, seem to put their lives on hold - rather than just liking football as in enjoying a kickabout, or standing on a sideline at some local playing field on a drizzley November afternoon.)

Is there really a car that doesn’t need its tyres topped-up, it’s washer water re-filled, a bulb/ LED changed in a year? That’s assuming the owner uses a car wash/ valet. I suppose you can get round windscreen wipers splitting by replacing them on the annual service whether needed or not.
Hi David, I must live in a world of neglectful owners, I've seen friends cars with tyre pressures as low as 7psi; and though I check my cars mechanicals assiduously, I never wash my car, I thought that was what rain was for :wink:
I think was going for something on a “What Have the Romans Ever Done For Us?” tempo: “my car needs nothing doing to it for 12 months at a time”

For a first service, it is mainly check nuts and bolts, that they aren't coming loose, and ensuring cables haven't stretched thus meaning braking or changing gear isn't as efficient as they should be.
Yes, don’t focus too much on the shop’s offer - bolts have a habit on undoing and cables stretch from new - that’s what they tend to check for.

In lieu of of any identified problems, you probably want to clean and relube your chain.

Some equipment on new bikes can be a bit rubbish - tyres, saddles, grips for example might want replacing. Do the type of tyres it came with suit the riding you’re actually doing?

Are you happy with the saddle height? Does it shift ok, do the brakes work ok?

Re: Stem Shifters

It looks like the Problem Solvers downtube band on lever mount or similar has been pressed into service as part of the “stack”. But, those Dura Ace d/t levers don’t have an integrated cable stop - you need outer to lead right up to the lever, of course. If you have the old-fashioned sort on your quill stem, you presumably need a pair of cable stops on the downtube.

Re: frame respray

I tried Spray.bike - don’t waste your time/money on a finish that is a lot worse and no easier to do than car shop rattle-can.
Now is the time to get your spray on - these warm, still days.
I find it’s best to have two frames on the go so you shuttle between them.

A couple of my still going strong efforts:
Canbrush Gentian blue (but their pink and red were poor)
Halfords Mercedes dark blue Pearl
Ice green colour-matched Raleigh Record Ace in Portsmouth

Re: SKS Chromoplastic mudguards: the long and the short of it

In you pr main photo, I can see you’ve bent the mudguard bracket forward quite a lot to clear the headset. It might be better to pack it a few mm forward with more washers?

You’ve correctly followed Velomati photo rules in having your valves in the same position, but the front tyre label is a bit off, if you were going for dead opposite the valves, so you lose a couple of marks there.
