content: Usually you have to buy the gearhub(1), a rim with the same number of holes as the hub, some spokes, then assemble the wheel yourself… which requires dexterity, experience, a tool to cut the spokes to the right size and thread them, and a tool to "re-camber" (slang) the spokes.Not easy, butthisservice is super-brilliant: they sell a rear wheel already assembled with a Shimano GearHub 3-speed and it has O.L.D.=127mm, so it's already compatible with every bycicle 8/9/10 speed frame! you just need a couple of shims, +1mm and +2mm, to put on the ends of the axle!Not too expensive, ~126 euro considering the exchange rate of the Swedish crowns in euros!Unfortunately ... the company is located in Sweden, doesn't accept Paypal, and it seems they don't ship abroad.But I love it! Want more services like this in Europe!!!(1) e.g. NEXUS-INTER-3 , SG-3C41, 36H , O.L.D.=127mm , 3-Speed

content: plenty of places in the uk will build something like that for you,yea it'll cost a few quid more but youll also be getting to chose exactly what rim and spokes you want

content: Quote from: DiTBho on August 23, 2023, 08:29:34 pmGood grief, does anyone still cut their own spokes? I've built a couple of wheels but I've always just bought the right length. A decent truing stand will save you a lot of pain though.There's no shortage of wheelbuilding services in Germany at least. Both discount suppliers where you can configure your wheels online for basically the cost of the parts, as well as more up-market shops that will do more exotic builds (and where you actually get to talk to the person who will build your wheel), at a price.

content: Quote from: switchabl on August 23, 2023, 09:24:11 pmFor both low profile and medium profile rims(1) you can find spokes for Campy Chorus hubs. I have always just bought the right length for them. No problem, often, indeed almost always, already threaded spokes.But I also built a dynamo hub of 3Watt. The hubs have longer flanges than any Campagnolo hubs, so you necessarily need custom-made spokes, which must then be cut and threaded.I don't have the equipment, they lent it to me, so I somehow did a couple of wheels for myself but I wouldn't want to do it to my colleagues, this is the reason for the topic: looking for a service for others!(1) I reworked- a pair of Campy Omega wheels, medium profile rims on Chorus hubs.- a pair of Campy Ypsilon wheels, low profile rims on Chours hubs.I am currently racing a pair of 90s Campy Zonda Wheels. I haven't reworked any high profile rims yet. No experience yet.Quote from: switchabl on August 23, 2023, 09:24:11 pmDo you have a URL of one of these shops? I would like to set up a speedhup wheel and see if they will ship it to my house and how much it will cost

content: The last custom wheel I had made was to fit an SRAM 2 speed auto hub into a track cycle rim. I got around the 'normal' hole mismatch by buying a BMX 20" 28 spoke hub and had a local bike shop do the spoke thing for about $200AUD at the time. I still need to grind some weight off the counter weights inside the hub to move the shift point to a higher speed from its current 21-22km to something closer to 30, going up a gentle hill and getting forced into top gear is a real slogHaving done some simple spoke replacements and debuckling over the years I still reckon getting this done by a shop was 'cheap'.Evidence of bike non useSomeone also needs to get their fat ass onto it after first cleaning the wildlife and winter/workshop accumulated dust off it.

content: Quote from: beanflying on August 24, 2023, 02:34:16 amI usually clean my wheels after every use, and when not in use, I put my precious wheels (1) into a wheel bag like this. The bag in a closet in a room dedicated to bikes.you need a detergent that is not too aggressive but capable of removing both dirt from the road and the oil that has fallen from the chain.you have to be careful not to hit the hubs so as not to accidentally degrease the bearings as well.just in case, I modified a hub to have sealed bearings(1) my precious wheels!Campy Atlanta 96 ---> 350 euro, second hand, re-camber(2)Campy Zonda 90s ---> 320 euro, second hand, re-camber(2)Campy Proton 90s ---> 310 euro, second hand, re-camber(2)Campy Omega wheels, medium profile rims on Chorus hubs ---> 140 euro, second hand, reworkedCampy Ypsilon wheels, low profile rims on Chours hubs ---> 110 euro, second hand, reworkedEach set of wheel bags, +40 euro(2) pull the spokes, check the smoothness, lubricate the bearings, check the symmetry on the testing skates, acceptable only with a 1/10 mm defect (difference beween what on skate-R and what on skate-L) using a special depth gauge with needle toolCode:. __depth | | depthgauge L-->| |<---R gaugewith | | withneedle | | needle| || |========| || || || || ||__|

content: Quote from: beanflying on August 24, 2023, 02:34:16 amThat's interesting, SRAM = Ex "Mavic" (American brand), I directly know Mavic only for their "Mavic Cosmic 90" wheels with golden anodized rims.You have to own a yellow bicycle frame to install them, I guess, but I have never used other products made by themI need to Google, as I only knowShimano Speedhubs (e.g. Nexus-INTER-3/SG-3C41)Sturmey Archer Speedhubs, (e.g. S-RF3/{ IHS3F.QBLS.AA3, IHS3C.QCSS.AA3)When you say track, you mean O.L.D.=120mm?next on my wishlist: I want a fixed gear bike, with Campy track hub for fixed gear, with no brakes but with a reticular wheel!!!sweet dreams ...

content: Now discontinued unfortunately but this was to make me the fixie that wasn't a fixiehttps://www.sheldonbrown.com/automatix.htmlhttps://bikesfornoreason.blogspot.com/2014/01/sram-automatix-2-speed-hack.htmlTwo speed and back pedal brake and more than capable of locking up the rear if you want to. Just a fun toy and I got the near new Felt track bike for a very good price with 5 or 6 track only sessions on it. Apart from the lever to the hub for the brake lock it looks and smells just like an unbraked track bike

content: Nice scoreFound a less grotty back end shot of mine showing the tugs and hand made stainless brake lever strap. Thin layer of rubber under the strap just to protect the frame.I also found the original invoice for mine from 2012I had to import from Germany at the time to get the spoke count I needed. Also the sprockets were tough to get locally so I added a few others in as well to go with what I could get locally.

content: Quote from: DiTBho on August 23, 2023, 08:29:34 pmComplete off-the-shelf rear wheels with various hub styles are quite commonly available over here. I would guesstimate a dozen different German online shops, plus some Amazon and ebay sellers.Google is trying to be smart and shows me German hits mostly, even when I ask for "bicycle read wheel" etc. -- so I can't easily see what is available in the UK. I assume you did some searching though. Is availability really so different in the UK?

content: @beanflyingchanged my mind, today I fully assembled a rear wheel using a RS-RF3 hub instead of the Nexus-INTER-3/SG-3C41.It weighs less (900g!!!), and from road tests it offers less friction.My definitive choiceI'm not a professional, from cutting the spokes, threading them, assembling a first draft of the wheel, and arriving at the finished and "camber-ed" wheel, it takes me almost 10 hours of work, considering 3 breaks, lunch, tea, dinner and short test on the road, so now for those of my colleagues who want to replicate the thing, I have to find an online service so I avoid spending my weekends assembling wheels for free!

I have only Googled for complete off-the-shelf wheels here, not custom assembly.Disclaimers: (a) No personal experience, no relationship etc. (b) The Sturmey Archer hub you eventually switched to seems rather uncommon over here, and I could not find any complete wheels including one of these. Shimano is much easier, both their 3-gear and 7/8-gear hubs.

content: worse still when the wheel is for a track bike frame, or 80s titanium like my Speedwell Titalite (6 speed derailleur), with an O.L.N.=120mm, and you have to fit a 3-speed internal gear hub(1).I somehow did it(no guys, I cursed so much both to assemble the wheel and to then mount it, thatI don't think I can make another one ... )(1) theoretically a 4 speed too, with first speed set on the direct drive sprocket, which would be super very nice and super useful, but you'd have to saw off the built-in brake arm because in this case those "donkeys" don't make a hub without it, and it adds nothing but extra weight (+260g!!!) and unnecessary space on the axis
