Wheels, Tyres and Brakes / Re: Alternative to Andra 30 rims

I have built probably over 100 wheels, but only one with a Speedhub. For the last 15 years or so I have always used the Sapim Polyax nipples for my builds. They may not always be necessary, but they don't do any harm and are cheap enough. I don't always use Sapim spokes, sometimes the right length wasn't available with Sapim so I used another brand, generally DT Swiss.

That is a lot more than I have built, but I built all the wheels on my bikes with the exception of my road bike that I bought as a complete bike.  That said, I did build a dynohub wheel for that road bike, so I am only using one wheel that I did not build.

I used Wheelsmith spokes and I am not sure which brand of nipples I used until I built my Rohloff wheel in 2013.  I bought the Polyax nipples for that wheel, and have used them since for all of my wheels.  And my most recent wheel, the Wheelsmith spokes were unavailable, I used Sapim spokes.

I suspect that SJS uses Sapim nipples and spokes, but do not know with certainty.

Probably.

Rohloff sell "special" spokes for building wheels with their SpeedHub. Quote from their website :

"Special spokes with a neck length of 2.9mm will be required when lacing SPEEDHUB wheels. If you are able to inform us of the ERD value of your rim, then we will be able to calculate the correct spoke length required for the build. The Rohloff AG are able to supply (via our extensive, worldwide network of distributors and dealers), specially finished Sapim Race spokes (DB 2,0/1,8/2,0 mm) in the most popular even lengths. These are available in black or silver with matching color, 14mm Sapim lock nipples."

I used Sapim Polyax nipples and Wheelsmith spokes on my Nomad Mk II, but Wheelsmith (no longer in business) made the spokes about 90 miles from my home, so I had some local bias.

General Technical / Re: Fitting a Bor Yeuh Front Low Rider Rack

Hi Adrian,
Interesting that you say on your link that you have converted the bike from 26” to 700c rims.
What are your thoughts about this change?
What 700c tyre size are you using?

It's not too clear from your photographs but it looks as though the hoop is secured with P clips, and it may be wrongly assembled.

Is it possible to completely removed the hoop and swap the two pannier supports left to right. You should then be able to refit the hoop on the outside of the pannier supports.

Thanks George.  I know very little about wheel building so useful info.  I don’t know what type of spokes / nipples SJS use but I have a couple of spare wheels from another brand of bike and the axial misalignment of spokes and nipples at the rim is terrible!

The good news, however, is that while my rims do not have any stickers left on them, I am pretty sure that they are Mavic XC717s which is what Thorn used around 2006 when my bike was built.  The Mavic web site gives a wear limit on the rims of 0.4mm.  I have measured the dishing and it is about 0.25mm (slip gauges under a straight edge across the rim).  The Mavic site also says there should be internal wear indicators (shallow holes drilled from inside the rim) that break through as wear increases.  No sign of those.  So I think I still have some life left in the rim(s).  I think I was lucky when I bought this bike as it does appear to have had very little use even though it is 20 years old.

When / if I do need to replace the rim(s) I think the Halo rims that PH mentioned would be best as they seem very similar to the Mavics.  I have Andra 30 rims on my other bike (with discs) and while I am sure they are strong, they are perhaps over strong for what I need.  And certainly heavier.

I want to use the Raven in India again next winter and I now think the existing rims will be fine.   I rode back to Somerset from Mid-Wales on it last week (230 miles) but I will now hang it up and use my other bike for the summer.

Bikes For Sale / Prototype Me'n'U2 for sale
« Last post by offthemenu on May 17, 2026, 11:01:07 AM »
Me'n'U2 for sale - Looking for £1500.

I am new to this forum. Please forgive me for joining mainly as a way to  advertise a bike for sale, but I thought the members here might find it of some interest.

I have been the owner of the prototype Me'n'U2 for over 20 years, though sadly had little reason to use it for the last 15 or so, as my children grew up.  I kept it with thoughts of grandchildren but as that seems unlikely I really cannot hang on to this rather unique bike any longer.

I understand the bike was hand built by Robin Thorn and his team in Bridgewater.  They used Reynolds 531 for the frame and a mixture of Shimano components , mostly around the Deore LX standard.  When I bought the bike second-hand from SJS, the new price of the production versions was around £2k but Robin estimated he would have priced this one-off prototype bike around £3k new. 

It has drop handle bars up front, with bar-end shifters, friction 3-speed chain ring and indexed 8-speed derailleur.

V-brakes front and back with a cable multiplier used on the rear.  There is  drum brake operated by the pilot which I found extremely useful and makes long descents safe and controlled.

It's a lovely bike to ride and once you're over about 5-6 mph it feels like my own solo. Trying to make sharp turns at low speeds is a little weird at first as the long wheel base gives you (the pilot) a slight sense of going sideways, so needs a bit of practice.   The drop handle-bars suited me, being similar to my other bikes. It's quite wide but that makes things feel very safe. The bar-end shifted work well and easily changed when riding in lower position, though aren't really an issue to get to when on the hoods.  Having a choice of hand position was certainly a benefit to me.

We had holidays in UK, Netherlands and Denmark using this bike, often carrying camping gear, and I can truly say the bike is a joy.  It does feel heavier going up hills, but I would then turn on "turbo-power" with a little encouragement to the kids, usually involving the promise of ice-cream.

Other notable features are the special adaptations made for a range of rider sizes. My youngest was a fairly short 4yo when we first got the bike, and could only just reach handle bars and peddles.   Robin was a true star and supplied us with additional cranks, so this bike will come with both double and triple drilled options to suit a wide range of requirements.

Robin also made a unique (well, I've not seen another) false seat post. This bracket bolts onto the top bar and allows you to place the standard handle-bar parts closer to the rear child (or the middle if that was necessary for you). This brings the handle bar back to a comfortable (safe) reach.

There two sets of peddles for the rear, which I selected for their foot sizes rather than anything else. A good fitting peddle, with secure toe-straps are essential as they really equate to the seatbelts in a car.  I used to swap my solo bike peddles over whenever we used the Me'n'U2, so these are not part of the offer.

There is a rear pannier rack (photographed on its own as I forgot to reattach when I took the main set of photos). There are braze-on's for a front rack , but the low- rider rack I used is not included.

Although the components are perhaps from a  earlier age, they work well and are all in pretty good condition. The paint work is still good, and to my eyes a lovely deep green colour.  There are a couple of small scratches here and there, none in and prominent locations and you should not equate the age of the bike to any notion of how worn it might be. It has been looked after.  I can detail all defects to anyone interested in taking this further.

The bike is located in Scotland, just outside Edinburgh. However, I occasionally have reason to drive to Bristol and would be willing to come to some arrangement find a suitable meeting spot with you.  This would require a fairly firm commitment to buy and is not aimed about offering trial demonstrations.

PS -struggling to attach photos - will add more when I learn how!

When I mentioned the Sapim Polyax nipples in my previous post, my point is that I do not know how important using Rohloff drilling is when you use Polyax nipples because the nipples are supposed to accommodate some angle mis-alignment. because of the design of the nipple.
https://sapim.eu/wp-content/uploads/2025/12/Polyax.png

When I ordered my Nomad Mk II frame and fork, the rims were shipped in the same box.  One rim had a tag with a hand written note that said Rohloff.  Otherwise I could not tell the difference between the two rims.

Thus, the people at SJS are likely much better to ask about rims with Rohloff angle drilling than I am.

I still have the original Andra 30 rims on my Raven Tour, which I use for load carrying and cycle-camping They have the CSS coating so they haven't worn much. If I ever need to replace them I will probably go for something wider, because I use 50 mm tyres. I have wider rims on my utility bike and most of the other 26" bikes I have built up, Ryde Andra 40 or similar.

I had lighter Mavic 717 rims on my previous tourer, again with 50 mm tyres. I did damage the rear rim on a heavily laden tour (all up weight 112-123 kg depending on the amount of food and water I carried), when I hit a pothole at about 50-60 km/h on a mountain descent. I replaced it with a wider Weinmann Alesa rim when I got home. The front rim lasted for 10,500 kms before it wore out and I replaced it with another Mavic 717.

When I got my Raven Sport Tour frameset in 2016 I fitted the Mavic 717 front wheel off my old tourer. Mavic 717 wasn't easy to find in 26", so for the rear wheel I got a DT Swiss 535 rim, which seems similar. I have 42 mm tyres on this bike, and use it for day rides with just a saddlebag, very occasionally for lightweight touring with rear panniers only. DT Swiss 535 rims are still available in 26" and 32/36H drillings, at least from German web shops, there is even a special reinforced version for E-bikes but I don't know if the latter is available in 32H.

Andra 30 and Andra 40 can/could be had with the drillings for Rohloff. This isn't the case for DT Swiss 535 rims, but it hasn't been a problem so far on my Raven Sport Tour.

Thanks for the replies - I will fit the Rohloff hub rings and look at the suggested rims.

I do not know how significant it is but the Andra 30 rims are drilled at the correct spoke angle for the Rohloff hub, perhaps more important on a 26 inch wheel than a larger one?


Edited to add:
SJS have both Halo and Andra 30 rims in stock at the same price.
Weights: 735g for the Andra and 475g for the Halo, the Halo having 2mm thick braking surfaces while those on the Andra are 3mm.  Internal widths are 19mm for the Andra / 20mm for the Halo, so OK for the tyre widths I want to use.
