Hello Terry. I decided to take the plunge and purchase the Brooks honey B17. When I removed the pentaclip , it fell apart as I was struggling to keep hold of it and keep it all together. ( I have Tremor in my hands ). So I turned to the font of knowledge, and watched your video. You told me/showed me all I needed to know about putting parts back together in the right order. Thanks Terry. I frequently return to watch your excellent videos.
Thank you Terry. I am about to replace my stock Brompton saddle with the same Brooks B-17 Special with hammered copper rivets. Now I know what mistake to avoid. Greatly appreciated.
A problem I've had is rounding out of the hex recess in the Pentaclip bolt after multiple loosenings and tightenings. The relatively high torque (15 Nm) makes it particularly prone to rounding out. (OK, I know you don't use a torque wrench but that's the tightness they recommend - actually pretty tight.) Went to Brompton Junction but they didn't sell spare Pentaclip bolts so, like you, had to shell out for another complete Pentaclip. Since then, I started using Wera Hex-Plus hex bits and Allen keys for everything. Ditched all my old hex tools. Hex-Plus bits are shaped so as not to round out hex bolt recesses. Five years on, I'm impressed with these tools. No more internal damage to bolt heads, no more general insecurity about wrecking irreplaceable hex fasteners. Just thought I'd pass this on. Nice video, by the way. Very useful, straightforward Brompton youtube channel.
Interesting video. The Brompton Pentaclip looks to me like an overly complicated engineering solution to what is essentially a simple saddle mounting clip. I have not seen so many washers and shims in a saddle mounting clip before, but I suppose it is one way to keep as many parts as possible exclusive to Brompton. As a heavier rider, if I owned a Brompton I would swap out the original domed cap head bolt for a standard hex head stainless steel bolt with nut and springwasher on the other side as security. It looks to be about M8 or M10 thread size. I can see that cap head rounding out again like your old one, especially now that they use a smaller size hex head key.
I used a new titanium bolt on my Lightweight. But now I have changed to a - lighter and better functioning, Chinese made, "Aceoffix" clamp, which uses wedges to hold the saddle fixed.
Thorough. Yes a torque wrench is a good idea if only to get an idea of the feel for the correct torque setting, but like you I have managed for decades with out problems servicing my bicycles. A car is a different matter. As you say at £38 you don't want to be replacing the Pentaclip too often. ATB.
I intended to change the bolt to titanium, and found the clamp absurdly complicated to put together again, with all those loose parts. So I found a much less complicated and - lighter, wedge adjusted, in a ring, AceOffix clamp from China! Since then I have changed to a printed saddle, now with an oval carbon frame and found a new and lighter Seat Clamp with room for those, also China and in Red! Finn. Denmark
@@terrysallbikes I am a former Racing Bike builder (6,8 kilo!), though now 76, and my Mtb is also extremely light from a full set of Shimano XTR parts, brakes (double caliber 9120) and wheels, and a Vision Kilo frame (Still with 33 possible gears, as I don't find -less gears better!). I can't even start on a flat road in the low gears, and get riding speed, but up an absurd hill, with a felt risk to fall backwards, they are fine! 😁Finn
Hi, Thanks for sharing. Are you keeping the damaged Pentaclip for spares. If not I am interested if they are for sale. I have an incomplete Pentaclip for 2 Brompton builds I am attempting. Whilst I have kept an eye out on ebay for bits I have not managed to come across any yet. Your parts would be of useful. Anyway thanks again for sharing your interesting and enjoy vids. Take care
@@terrysallbikesIt's not designed to be flipped over. The meaty part of the clamping jaws and the bolt need to be underneath the rail to support the rider's weight safely. Flipping it means there's far less material supporting the saddle and rider. If it works loose the saddle could detachmore easily that way round. Plus you also have less clearance under the saddle with it flipped. I'd never do it.
@@graemeelliott4147 That's incorrect, in fact. The official Brompton PDF data sheet says: "The Pentaclip allows two saddle heights. In the upper position you gain about 20mm but this will make the folded bike larger."

Thanks for your kind comments, really pleased to have been some help, believe me I’m often looking for help/information on here👍

Thanks that’s appreciated, good to know I’m helping someone now and then👍🚴♂️

Thanks, that’s useful to know I’ll check them out it’s so frustrating when you wreck a bolt this way👍
I'll be sure to check that when I switch over to my lightweight saddle. Thanks Terry!

I hear what you’re saying, however I haven’t seen another way of mounting a saddle that has such versatility
Thank you very much for sharing your experience.

You certainly seem to have some good lightweight solutions

Very helpful. Cheers 👍
Thanks 👍🚴♂️
I transformed the riding position on my Dawes touring bike with a pentaclip.
And the handle on the original toolset functions fine as giving mere pover.
👍
And You may turn the clip inside the saddle, to make it fill less.
👍
In this age of recycling and cutting down on waste, it would be nice to see bromptom selling spares, instead of buying the whole item.
so, for sure, Brompton does not sell the washers and plates?
Cuz capitalism incentivizes profit at your expense

Hi I’d love to help you with that but will be keeping it for spares myself, what’s broken/missing on yours?
@@terrysallbikes A good idea.
Many thanks again. Take care.
The problem with the "flipping over" is that you are loosing some (for me) valuable millimiters (about 1cm) of saddle height as well.
Like many things in life there’s often a compromise to make
