Brompton - Changing from R (rack) to L (fenders only) - rear fender

So I spent too long last night switching out the rack and installing the rear fender after it arrived from BikeBrompton.

After which I realized the rear fender is extremely floppy and probably needed mudguard stays to firm it up. However BikeBrompton has not provided any additional parts beyond the fender, flap and screws. Before this all I heard is I need the fenders and that's it.

Can anyone confirm if I need to buy additional stays when converting from R to L-types?

My L has 3 pair of struts , you get all 3 of them? (X-version, I read, they used Ti wire for the struts (vs stainless) )

I was told that to add a rack to a Brompton, you have to change the fender; the attachment is different. This is why it's more expensive to add a rack to an L bike after the fact rather than have it pre-installed on an R.

true the rack it self is a mudguard support .. So mudguard has different holes in it,..
the L has 2 struts to support the 1 little wheel on the mudguard to let it roll in the under fold.

this , from Spain, is a further reinforcement of the L style Mudguard Milian PartsPlablo Milian Parts

I think the struts themselves are the weak point for the the L style. I have had to push mine inward to prevent the the mudguard from rubbing the wheel.

The struts are very stiff. The weak point IMHO is the guard. Swinging the wheel under and whacking the guard down on its little wheel, or inadvertently putting too much weight on the guard while folded, will break the guard. That reinforcement is a good idea to prevent this.

True it happened when I first got it, but the fact that it happened to be this part and not the fender itself indicates that they are the weak part. It is good that they did widen since that is better than the fender breaking.

At least Brompton acknowledged the weak point and tried to fix it?

Yeah, I was naive enough to think all I needed was the fenders+screws and nothing more. My LBS (the only Brompton shop here) tells me the stays will take FOUR MONTHS to arrive. Their last shipment was mere weeks ago.

So I'm guessing they either did not bring in any stays at all or the bare minimum, OR a large troupe/gang/skein of Brompton owners suddenly decided to change their Rs to Ls and purchased their entire stockpile?

There is basically no way to 'officially' buy official parts from overseas Brompton dealers. One of the first places I checked was SJScycles.com, but the usual "this item may have selling restrictions to your country" prevents me from ordering ANY Brompton parts from them.

I guess you do not see it because you're in the UK too.

It's Brompton's strategy to prevent people from shopping for the best deals internationally. It makes sense to protect the local dealers, but over in Singapore it's painfully flawed because there's only one dealer and if they do not have it, too bad! Just sit tight and wait SEVERAL MONTHS for the item to come in. Either that, or one has to find obtuse - and often more expensive ways - of getting a friend/family/stranger to buy it and bring it back (in exchange for money or a lunch or dinner, of course).

To be fair, their in-store customer service is good and efficient, but I doubt Bose or Vertu or BMW or Rolex treat their customers buying their relatively high-priced goods with such indignity.

So you wrote them yourself, or just figured the automatic zone recognition software was the final word?

If it helps , try buying thru a US retailer and having them ship it to you.

your local seller seems to habitually short you on parts, if the pump issue is any indication ..

Before you order the stays, do make sure you've understood Bob's post (number 4 above). It'd be a shame to wait for the stays only to discover you have the wrong fender. The R- fender would have an extra bracket that wouldn't currently be attached to anything on your bike.

No I did not write to them, but I figured - wrongly perhaps - that being in UK, they would be less likely to override Brompton's arbitrary rulings. I tried using a freight forwarder (delivered to a specified UK address and the company will forward it to my overseas address), but apparently they set up the system to make that impossible too.

Ultimately I did find a convenient solution, but only because the timing is very fortunate. My wife is returning from Australia in a week and they do carry the parts there.

Even so, it only takes a few weeks in Australia for the shop to get the parts from Brompton if they do not have stock. IMO that's a huge difference from a several months wait.

Here are pics of the newly installed rear fender:



The second pic shows 4 holes for what I assume are to accommodate the roller-wheel and 2 stays. And one more stay will be mounted near the brakepads/stop.

yes front strut has an oval plate reinforcing the mudguard, strut-arch passes between them its under the mudguard
Factory stock, its riveted together.. A poprivet will do the same, after market.

stack sequence... humped plate, strut, mudguard, and top plate

wider spaced holes are the rear roller, 2 struts there ... 3 in Ttl.. \

+ L bracket under the brake bolt ..
