Re: 26" nutted rear wheel - new QR possible?

@gaz
It's steel (Reynolds.) The idea of forcing the dropouts slightly apart to fit the longer hub is painful, so probably will look around until a 130mm
can be found. Actually, my old rear wheel is sound - it's just badly out of true and the nipples are now welded to the spokes/rim - totally immovable. Not sure if my LBS or any, could release the nipples and true the wheel.

@Cadence

It's a 7 speed freehub (cassette.)

This looks promising https://tinyurl.com/3hdcsnvm - the seller describes it as "Rear hub 135mm wide across the locknuts" whatever that means. I measured across the inside surfaces of the rear dropouts = 130mm.

Re: 26" nutted rear wheel - new QR possible?

Definitely worth trying your local bicycle recycling scheme
I looked a few months ago - local bike orgs, gumtree, Ebay - and it seemed they were asking not much less and sometimes equal to a new wheel. One guy was selling a wheel that looked like it was pulled out of a canal, for 30 quid.

Re: 26" nutted rear wheel - new QR possible?

...there's good info here:
I replaced the rear wheel axle a few years ago. The old one is still in the garage, so measuring it would do, methinks. I believe almost all the axles in 26" wheels on old MTB's are either 130mm or 135mm. The Tredz page doesn't have any tech data, my live chat doesn't work (for some reason) so no way to find the new Tru-Build wheel measurement. I'll assume they use the default 130-135.

26" nutted rear wheel - new QR possible?

The rear nutted 26" wheel on my Raleigh 90's MTB is decrepit. New nutted wheels seem to be extinct.
Can I buy a new QR wheel and fit it on the bike?

As I recall, on inflation there did seem to be a slight inner tube hernia adjacent to the valve, which is why I deflated, massaged the tyre and reinflated. Not sure if this exonerates a defective tyre - if that's the case. There are 2 new identical Marathon's in the mail, so I'll keep the jury out on Schwalbe until the new tyres have had a fair trial over the coming months.

So, was the bump bump bump because you were riding with the rear tyre partially unseated?
Previous to the trouble, I'd removed the tyre to fix a puncture. There was some difficulty getting the tyre properly reseated and after inflating it, I wasn't happy as it looked very slightly poorly seated around an inch or so at the rim. I took the tyre off again, reseated it, and inflated it to 6.5 bar as recommended by Schwalbe. It looked good, so off I went.

I have canti's - and they're properly alligned, no tyre rub.

Re:

Schwalbe tyres are made in Vietnam and Indonesia, and it's assumed Schwalbe have good quality control wherever their goods are made. The failure rate may be more noticeable because of very large numbers of Schwalbe tyres in use giving a large data set and higher probability for failure.

The, "I've ridden on Schwalbe tyres for 4 years and never had a puncture" claim isn't due to tyre toughness, it's due to good luck. A couple of years ago cycling out from central London to Newbury, I had three punctures in 4 hours - on Schwalbe Marathons.

Are you doing that in a way that might get those solvents on the tyres? I wouldn't.

Jonathan
I do this outside and wash the solvent off the tyre with water. From now on, I'll try warm water, washing up detergent, or one of those unjustifiably expensive bike cleaning fluids - presumably Fairy Liquid solution coloured pink.

Re: Sidewall failure - GT85?

Taking the tyre off at the beginning of a 5 hour ride would have been too much of a hassle. I did have a close look but saw nothing.

Sidewall failure - GT85?

Had a sidewall tear yesterday on a rear Schwalbe Marathon Greenguard 700x32.

There was a loud bang going downhill, luckily no drama, just stopped and saw an inch of steel wire sticking out of the sidewall and a large tear in the inner tube. The tyres are about 2 years old with approx 3k-4k miles, and still a reasonable amount of tread. For the previous two rides I'd noticed a regular thump-thump on the rear wheel, so I suspected a bulge but couldn't see one on inspection. 150 miles later and failure.

This coincides (coincidentally?) with my starting to use GT85 to lube the chain, jockey wheels, cassette. There are anecdotal claims GT85 is bad for tyres and a few cyclist say it's responsible for sidewall damage. WD40 is also said to be damaging to tyres.

For years, I've sprayed the cassette, chain, jockeys and drive train with either petrol, paraffin or diesel to clean the grime and oil off, then lubricate with Multi-Purpose 3 in One oil. Recently I switched to GT85 as it's easier to spray on than applying the drip 3 in One.

I got the Schwalbe's because of their reputation but TBH, my previous Contact Continentals seemed more durable as well as a bit sharper handling.

Re: First Ton +

Which train company did you use from Basingstoke?


South Western Railway (not aware there is another company serving Basingstoke?) The bike rack arrangement was twin floor hoops to hold the front wheel - causing the bike to fall over once, around sharp bends at Gillingham. Prefer the trains to Waterloo where the bikes are secured with straps to the fold down seats.
