Brompton ‘specialist works’ charges Scotland

Apologies in advance for the long post!

My 2017 M6R is in need of a new rear hinge & bushings as well as replacement frame hinge pin and (probably) stem pin - all jobs which, for the home DIY mechanic, are effectively discouraged by Brompton in various ways including the need for expensive specialist tools not readily available to public, leaving aside the obvious risk of wrecking the frame itself if it all goes pear shaped…

I live in the Scottish Borders, with a very limited number of Brompton dealers within reasonable distance, a number of whom I’ve contacted say they’d need to get the tools sent from another branch to do the requested works, which doesn’t fill me with confidence that they‘ll actually be competent to do the job.

I’d checked a number of Brompton agents’ websites for prices to get a rough idea of likely costs - e.g. London’s Phoenix Cycles rear hinge replacement currently being around £75 and a frame or stem pin £50 inc parts. The Brompton Man in Somerset is £25 and £30 respectively plus parts (approx £20-£30 for the rear hinge kit and around £10 for a pivot pin).

Imagine my surprise, etc when I received the following email from a Brompton recommended outlet in Scotland (no names, no pack drill!) having asked for a quote:

”Without seeing it would be a rough estimate, but based on the worst case it would look something like:

Rear hinge         £30
labour            £100
Main frame hinge   £10
labour            £100
Stem hinge        £10
labour            £100

TOTAL             £350

This is based on the worst case scenario of EACH hinge requiring two hours for removal and refitting. They will typically take one hour each, which would be £50 per hinge + parts”.

Now, I realise that the implied ‘best case’ scenario might mean that I’d be looking at around £200 for all three hinges at this dealer assuming one hour for each (I’m aware rear hinge bolts can be ‘fun’ to remove), but this still looks steep - double that of The Brompton Man and £25 more than Phoenix at ‘London prices’. Moreover, I fear if I went ahead with estimated repairs, said dealer would simply say each job was a b****r and charge the full £350 anyway…

I’ve also seen a YouTube video of rear hinge replacement ( the bolt eventually needing drilled out!), which - even allowing for the limited editing - did not appear to be a 2 hour job.



[BTW - I’m not knocking Phoenix, who did an excellent job of servicing & rebuilding my BWR rear hub for only £80 - a job that was considered uneconomic to repair by another Scottish Brompton dealer, who simply sold me a new rear wheel. (My daughter lives in London and took the old wheel to Phoenix) - I have thought of couriering my whole bike down to her to have the works performed there, but it’ll leave me without my bike, which is used for daily commuting, for longer than I’d like, not to mention risk of damage in transit.]

I‘d welcome any comments regarding the estimate costs as being reasonable/unreasonable and/or recommendations for a competent LBS within 60 mile radius of Gretna - Brompton affiliated or not - that’s both familiar and equipped to undertake above jobs.

It can take over two hours to get the bolts and old bushes out of the rear hinge, or it can take 10 mins. You never know. Rear hinge can be DIY as Brommieplus will sell you a suitable piloted reamer. The hinge pins need the Brompton tools (and oversize pins) or a fairly well-equipped workshop. It's one of the big downsides of Brompton ownership: some reasonably routine service jobs require special tooling.

If everything goes perfectly well a person who has the right tools and has done it before will be able to change the rear hinge as well as the hinge pins in roughly an hour total w/o hectic. The hinge pins on the main frame and the stem are typically a no-hassle job if you have the hinge pin press from Brompton but they only rarely need replacement. The rear hinge is another story but someone experienced will be well prepared for the worst and thus not waste time with polite efforts that may only work in an optimal case - they will go the direct route and waste no time.
"All works perfectly well" would not be a wise calculation but 3 hours in total should be plenty and leave a lot of buffer.

So I'd say the quote you got from the Scottish dealer sounds a bit obscene. Possibly you could ask Ben Cooper in Glasgow - probably he is to busy but in case he is willing to do the job his work should be top notch.

I did indeed contact Ben at Kinetics but as you suspected is too busy to undertake work on the standard Brompton at present.

The frame hinge on my B seems to be one with most play and the hinge clamp, which I renewed only 6 months ago due to a developing hairline crack has already gone the same way. I don’t use excessive tightening force and am seeing around 1mm gap between frame and clamp, so just within tolerance.

Despite logistical challenges, I’m erring towards sending the bike down to Phoenix via my daughter in London (unless of course they’ll let me send it directly!).

Thanks for replies :thumbsup:

Just FYI - I took my Brompton back to the supplying dealer to asses lateral play in the rear hinge. They basically said "They all do that sir"

I was still a little concerned - not so much because of the play, but because it was creaking really badly. As it turns out, the drive-side hex-bolt was a little loose.

Some thread lock and (from memory) a 4mm allen key sorted it. Less side-to-side movement and no more creaking. Though you do have to remove the chairing to access the drive-side hex.

This is what it used to sound like...

Word of caution though. In my typical "brute-force-is-the-answer-to-everything" approach, I'm pretty sure that bolt can now no longer be tightened nor loosened any more as I think I rounded it a bit. So if you did check it/them and found them a little loose, it's probably worth checking out the official torque figures.

They're only a quid or two from eBay. Given how tight the bolts are, I bought a 3/8" drive 5/32" hex bit.

Truman, I feel your pain, brother...I had a rear triangle pin replaced along with getting a new seat post fitted and had to mail the bike about 1200 miles to a repair shop. That in turn required I make a shipping box from a freebie bike box from my LBS. I have since found a great shop much closer. Having to replace the frame hinge pins seems a bit much, as I have tens of thousands of miles on my 2010 and they are still solid. I have no idea if this helped my rear hinge reliability but I have a tappped hole for the hinge bushing with which I inject heavy oil to lube the bushing. It has been thousands of miles since it was replaced and it is still tight and true.

Thanks for all replies - by way of update, I ordered the Brommieplus full reamer set for service/replacement of rear hinge myself. Delivered in around 10 days and did the job last night. I followed Ben at Kinetics advice on getting the bolts out, which took less than 10 minutes! Old bushings extracted with tap, new ones pressed in and reamed, a drop of ’loctite blue’ on the threads and torqued up to a mighty 10 Nm. Total time for job (as a first timer) was around 1 hour and I reckon less next time - but appreciate I may have been lucky with bolt removal on this occasion! (Rear hinge was last replaced just over 2 years/5500 miles ago).

I’d do the frame hinge pin myself as well, but couldn’t justify cost of the tool. I definitely have some play as I’m getting hairline cracking in aluminium hinge clamps after only a few months of riding.
