Extra tools

I needed an extra tool for maintaining my Bromptons recently & thought it was time to think about serious servicing (ie just preparing; nothing necessary yet). Aside from a sole Brompton dealer in the city area, I’m probably now more knowledgeable about Bromptons than most local bike shops. Converting Robinson, my first Brompton, from 3-speed to 6-speed BWR was an interesting first-up project & it was “highly educational” in researching specs, gear ratios, parts requirements & sourcing. Obtaining parts & accessories has been an issue, with choices of traveling for them, ordering locally (too slow/traumatic?) or ordering online. Here I’ve found a good appreciation of Bromptons is really handy in ensuring I end up with the correct parts. I expect that taking a Brompton in for major servicing is going to very inconvenient for travel or turnaround time (not to mention the worries of local shop service quality or understanding?) & so who better to trust with the work than me? “How hard can it be…?”

So, I’ve now got myself prepared with the various specialised tools that I’ll probably need. (Of course, whether I take the plunge & use them is another matter but we’ll see.) I’ve also found that Internet research on maintenance issues beforehand is a wonderful thing – as long as you think to do it. My recent boo-boo with Ralph’s Alfine 11-speed rear hub dust cap was a bit sobering but it just looked so much like a snap-on rubber seal & it came off & went on (mostly) & all was well – until I put the rear wheel back on. Hmmm… lots of drag in the chain & unrideable? Numerous strip-downs & reassemblies later, I turned to the Internet & found an exploded diagram of the hub parts – & noticed a funny-looking tool. More research & then it hit me: it was to screw on the dust cap! And who would have expected the cap to be secured with a left-hand thread? Hmmm… (Something in my defence was that the dust cap was rather chewed-up & the “tighten/loosen” directions were unreadable. I had thought the marks on the dust cap were from the chain coming off (Ralph does some funny things at times) but on closer inspection I think someone’s “butchered” the cap through not using the correct tool for removal/installation? A new dust cap – & the correct tool – later & Ralph is purring like new.)

Here’s my Brompton “extra maintenance” tools collection (some new although others have seen service on other bikes) –

Alfine hub right hand dust cap tool
36mm headset spanner set (thin & thick)
Crankset removal tool
Bottom bracket spanner
Bottom row –
Cable cutter
Circlip pliers
Relevant cone spanners

I’m still undecided about the Alfine 11-speed hub lubrication plans… create a DIY oiling kit? purchase the genuine Shimano item? & of course, sorting out the oil to be used?

Finally, a pic of my “office” – ideal for little wheels TLC?

Front luggage options

The Brompton front luggage system is quite brilliant in design & operation. Robinson, my first Brompton, came with a C bag & it gets lots of use. When Ralph, my second Brompton, came along & I also setup the Bromptons with on-board tools & bidon cages, it was time for a second luggage bag – but one of a smaller size.

In my research the Ortlieb Mini-O bag seemed ideal but I found it was a teensy bit small for an iPad. Rather than use this as justification for purchasing an iPad Mini along with a Mini-O bag, I looked at what I could adapt.

I found a handle-bar mount bag that would fit my iPad, camera, etc & then fabricated an alloy adapter plate to attach to the bag’s support system.

On the road it’s been working well. My alloy adapter plate is admittedly now at version 2.3 but I’m pretty happy with it. (Certainly gives me a better appreciation of what goes into the Brompton & Ortlieb bags & frames?)

Keen testing

I’ve made good use of my Keen Commuter II cycling sandals since they arrived last Christmas. I fitted them with MKS cleats & I’m very happy with them for cycling. What I wasn’t sure about is how they’d go for their “other uses”? That is, bush walking & beach wear (after all, when I’m traveling – especially in our VW T5 Campervan – I want to minimise the variety of footwear I carry).

Early on they got a workout for bush walking & they passed the test very well. The toecap & stiff sole both give good protection & support for rough surfaces. I can now report on their use as beach sandals & they didn’t pass so well. Sandals & soft sand are ok for me but the toecaps retain the sand too much. As for the water test, the upper material took far longer to dry than my usual Teva sandals (& what does that “waterproof” label on the Keen sandals really mean?)

MKS Pedals

I’m a fan of clipless pedals but on my folding bikes I sometimes want flat pedals & for travel/transport I want the bike compact. To me, the MKS removable pedals have filled the bill. I have flat & clipless pedals that are the “pre-Superior” models (the Superior model uses an adapter that has an improved locking device but there isn’t a clipless model & the adapters aren’t compatible with the earlier adapters). For the clipless pedals, you need to use the MKS cleats for your shoes & these are compatible with both MKS & Shimano clipless pedals (ie the Shimano cleat is not compatible with the MKS clipless pedal).

MKS provide a yellow nylon circlip for the non-Superior removable pedals, as a safety locking device for ensuring the pedals don’t unexpectedly disconnect from the adapters. To me they are a nuisance & slow down the removal of the pedals when necessary. For the clipless pedals they hardly seem worthwhile because your shoe is locked to the pedal, but on the flat pedals a soft-soled trainer-type shoe is broader & may come in contact with the adapter (& possibly release the pedal). My solution was to fabricate an alloy plate to bolt to the adapter end of the flat pedal, ensuring that any shoe cannot come in contact with the adapter (see pic).

When Ralph came along, I noticed that the front tyre can release the right side clipless pedal when Ralph is folded (it seems to be a factor of the widened frame & the Kojak tyres (see pic). As I don’t often have to remove the right side pedal, I’ve fitted the MKS circlip on that side.
