So far on this thread you have had a pop at Spa, Boblo, CJ, Meic, "supposedly the best wheelbuilder etc." and me.
Are you sure its me thats argumentative?


They're called differences of opinion. You seem to think anyone who disagrees with you is wrong.

Just noticed how many posts you've made in the past few months since you joined on here. And 4.84 posts per day! Impressive. And I thought I was a sad old miserable git with nothing better to do than discuss spokes. :lol:

I dont have to ask any wheelbuilder why wheels fail, because I have been building wheels for 40 years. Thats what makes my opinion worth listening to.
You say you get your LBS to build your wheels, so I suppose that makes your opinion more valid than mine.

But on April 1 you said butted spokes became De Rigueur in racing in the seventies. Butted spokes were certainly available before the war, did it take those heroic race mechanics 40 years to get round to using them?


That is correct. Double butted spokes became de rigueur in the 1970s not just in professional racing circles but among wheelbuilders in general who, rightly or wrongly, followed the trends in racing circles. Double butted spokes were not widely available before then, nor generally believed to be better than straight gauge spokes. Even today there are still a few professional wheelbuilders of a certain generation who continue using straight gauge spokes because they believe the advantage of the extra strength is better than the greater elasticity of double butted spokes. They're also cheaper :lol:

The fact of the matter is that the type of spoke used for light touring is far less important than the quality of the wheelbuilding. A not very good wheelbuilder using an elaborate mix of spokes on the rear wheel will build a not very good wheel. :wink:

Re: Touring wheel advice please?

I'm afraid there are some people here who, if given the choice, would still rather have their touring wheels built by Spa than a team mechanic with 40+ years experience. :shock: Doubt, though, that he was still using straight gauge spokes after double butted became de rigueur in racing circles in the 1970s.

Re: Touring wheel advice please?

[my LBS obviously has a lot more skill and experience than me but he also seems to think he knows what I WANT better than I do.

If your LBS obviously has a lot more skill and experience than you, maybe sometimes they do know better than you.

Let's take the example given at the start of this meandering thread. Somebody wants a pair of wheels built for light touring. They've gleaned on the internet that the rear wheel should have single butted spokes on the right hand side otherwise it's poor design according to Engineering Science. So they pop into their LBS, where they've been building good wheels for 20 years but curiously never a pair with single butted spokes on the right hand side, and insist that that's how it has to be done. Right. :lol:

Maybe I'm just lucky. In the past, I've naively trusted my LBS, and I've had generally very good results. Except once, in the early 1980s, when supposedly the best wheelbuilder in the UK at the time built me a dud rear wheel. :shock: Must have been a one-off.

There are two factors in a good wheel: the craft skills of a good builder and the engineering science of good design. A good builder can largely compensate for poor design and a well designed wheel can last okay despite poor building, but when you're paying what it costs for a hand-built wheel you really want both to be right.

The last thing you want is a debate regarding the design of your wheel with the craftsman who'll build it. Better go to one who's happy to take instruction from those who do understand why it makes good engineering sense to have more metal where tensions are higher!


Chris, this is getting a bit off topic, but it's an interesting discussion.
There's theory and then there's reality.
First, few cyclists have the required background in engineering to be able to discuss such fine details with their local bike shop without sounding like a tosser.
Second, mechanics have been building good wheels for decades by getting the tensioning right without needing to resort to single butted spokes, offset rims, etc. That's not to say that traditional techniques cannot be improved.
Third, while there are general principles of design that everyone agrees on, there is hardly a consensus among wheelbuilders about the finer details you're going on about.
Finally, if a cyclist is so knowledgeable about how to build a wheel, s/he should leave their poor lbs alone and build the wheels themselves. :wink:

I agree. It's a pleasant job you can do without getting your hands dirty. It's even easier if you get the rims, hubs, and spokes from a wheel-building LBS so the spokes are the right length.


Edinburgh Bike Coop do a one-day wheelbuilding course that teaches you the basics. And at the end of the day, you can ride away with a pair of wheels that you've built yourself to your own specs, with rims, hubs and spokes of your choice (they sort out the spoke lengths for you before you start the course). May not be the best built wheels you'll ever own, but it's a great way to get started. :D

Any decent bike mechanic can do that, but will they?

Trouble is, most good mechanics and wheelbuilders are of a racing persuasion. That's the sort of cycling they know most about, that really interests them, and for which they really enjoy building wheels. Request a touring wheel and their disdain is sometimes almost palpable. They'll build one, but they won't like it. If you then have the cheek to suggest they build it a bit differently to the way that's good enough for any racer (therefore more than good enough for you, a mere tourist!), using a single-butted spokes on the right hand side, that are not used in racing and that the builder therefore does not keep in stock and that (unbelievably!) cost even more than some of the best double-butted spokes he does keep in stock, and you have a perfect recipe for disagreement and disappointment.

There may well be other wheelbuilders who are just as eager as Spa Cycles, to build rear wheels in the way that cycletourists have found to be most reliable in the long run (i.e. with heavier spokes on the tight side and lighter on the slack side). But unless they tell me about this, I cannot tell anyone else about them.


According to the OP, his local bike shop sounded happy enough to build him a pair of touring wheels. Using his local shop also means he can bring them back easily enough if there's any problem, which there shouldn't be, plus save on the postage. Whether he needs single-butted or heavier gauge spokes on the right-hand side of the rear wheel is debatable. It certainly doesn't guarantee a better built wheel.

Not sure about that. I bought from them because they have a good rep and were much cheaper than my local supplier. The last pair of wheels I bought locally (XT/Mavic 719) were well in excess of £200. Spa are significantly cheaper though I still believe my local builder is better.


If I were having a new pair of wheels built, I'd use the better builder. If the better builder also happened to be my local bike shop, even better! :D

Re: Touring wheel advice please?

... I am doing longer and longer rides on country roads, and have the possibility now to do some light weight touring, I have spoken to Mick Madgett at Madgetts in Diss (my local-ish bike shop), about getting some handmade touring standard wheels made up, prob on Deore hubs of some grade (135mm wide). He has shown me a couple of the kind of 700c touring rims he uses, and reckons on a starting price of about £150-170 a pair.

The issue I suspect with my present wheels is comfort (they are medium section and this very stiff), and weight (they aren't designed for carrying weight).

So....if I were to invest in a new set of wheels, would the increase in comfort be noticeable? Would the weight be significantly greater than a set of roadie wheels? What grade of shimano hubs would you recommend, Deore, 530, XT?


Have you tried a pair of 28 x 700c Marathons on your present rims? If the rims will take them -- check with Madgett if unsure -- you will find they're noticeably more comfortable than your 25 x 700c Paselas. 135mm MTB hubs aren't necessary for light weight touring. I've been using old 126mm Record hubs and equally old Mavic MA40s with 28 x 700c Marathons for years without any issues for light weight touring. New Mavic Open Sports are just as good. On another bike for fully loaded touring, I use 130mm Tiagras and Mavic A719. Heavy, but bombproof.

If your current rims won't take 28 x 700c Marathons, and you're happy with Madgett, have him build you a new pair of wheels. I wouldn't bother with Spa in Harrogate. They're overhyped on this forum. Any decent bike mechanic can build a decent pair of touring wheels.

Re: Ireland southwest coast

Just a short follow-up to my OP. Lovely part of the world, friendly people, and happy to have done the trip. But it ain't cheap Ireland (as we knew) and there's lots of fast traffic on the main roads. The hostels we stayed at were excellent (although we did hear about one that's a dive) as was the food. However, the pubs were sadly disappointing (giant tellies everywhere showing football til 9:30pm every night; awful American beers common). Use a good map (we had the new 1/100,000 Xploreit which were good, but the OS 1/50,000 are better I think) and stick to the backroads, which are very quiet. Surfaces were generally fine (I was using 700 x 28 Marathons no probs), although a few stretches of chippings. The biggest hills we encountered were smaller and easier than North Yorkshire, which is what I'm used to. Best part of the trip was the north coast of the Beara Peninsula: stunning and over Gougane Barra (2 cars the whole day). Oh, and the weather: hah, we had blazing hot sunshine everyday except for the last!

Re: NOT getting shot of my Bob Jackson ST

Check the clearance between the chainstays where they come out of the b/b! I've got a BJ ST from same period with 700 x 28mm Marathons that only leave about 3mm clearance on each side!!!
