Re: Sturmey CS RK-3 stripdown - a query - now solved

25miles this morning on the Moulton. Out very early because it's going to be a scorcher today. Not ridden Moulton for over a week, so any of the soft grease that would have settled, must have done. After and during the ride, there was no leakage seen. Also, I was riding in near silence. SA hub was ...

Re: Roller Pinion + Shaft Drive

The bicycle as a basic design of which we have now, was invented a century ago. They still haven't improved that design despite many many ideas. This is just yet another dead end IMHO. I saw this report at the beginning of the week, and felt it was a solution looking for a problem. But, nonetheless...

Re: Sturmey CS RK-3 stripdown - a query - now solved

Good morning guys.......................... One issue that I found last time I had it in bits and this time too, is that the pawls on the LH end - forgive me but I'm not sure which ones they are technically - but they're the ones that engage on the inside of the hub shell - don't seem to have a ver...

Re: Sturmey CS RK-3 stripdown - a query - now solved

............. I note also that (IIRC) the individual spare parts appear not to be available for this hub, so barring the (few) parts that are used in other SA hubs, if you encounter a problem a whole new centre is the only solution. cheers I'm finding this thread (and the one alluded to in which Mi...

Re: Sturmey CS RK-3 stripdown - a query - now solved

The ring has shifted, using a punch. The secret was to apply a larger hammer ( thanks for the tip, Mick). A couple of strikes, even without much input from me, did the trick. Thanks for the help everybody. Onwards I go into the depths of an internal hub, as a complete virgin (no funny moments, pleas...

Re: Sturmey CS RK-3 stripdown - a query

Thanks for the advice so far. Most informative. I've had a preliminary attempt with a mild steel punch. It seems not to damage the hardened steel casing. But, it hasn't shifted. Maybe I don't have the confidence to give a sharp enough blow. Like Mick, I'm a little "offended" to apply this ...

Sturmey CS RK-3 stripdown - a query - now solved

Hi, I'm stripping a Sturmey Archer CS RK-3 hub. I've never stripped an internal hub before, let alone this particular model. I have a query and I can't find answer on the internet. I'm at the point of screwing out the planetary gear assembly from the hub body. On the internet (but applied only to ot...

Re: Pictures of your recumbent

Pic of my Giro 26 - not the most inspiring photograph but it was on my first ride out 6 months ago so I was pleased to get anywhere without incident. :D Andy Andy Giro 26.jpg I'm glad you had no "incident", Andy. I do remember mine whilst I was still upskilling on a 2 wheel 'bent. However...

Re: Favourite tea shops

I chanced upon "Laggan Stores Coffee Bothy and Gallery" earlier this week whilst out on a ride. It's well worth a visit, with home made soup amongst the fare. It's about 30 miles south west of Aviemore, on the A86. The welcome was warm hearted, inclusive of cyclists and I had a little conv...

Brighton to London - trike on the train?

I've been looking in the archives, and think I have an answer. But the threads aren't quite up to date, and I'd like to check out more recent experience. I intend camping in Brighton before the London to Brighton ride in June, and going up to the start on an early train. I'd fashion a bag for my fol...

Re: 8.5 mile commute for a beginner cyclist?

I agree with all the comments about it being feasible and building up to a full week's commute in stages. You'll be surprised just how soon your legs and stamina get up to the needed level. Don't rush it, and don't be dominated by clock watching. There's pleasure to be had simply by riding, even in ...

Re: Brompton Gears, How Comparable with a Full Size Bike?

A gearing comparison is independent of wheel size. A "gear inch" is a way of indicating how far a bike will travel forward for a single rotation of the pedals. If it travels further, more effort will naturally be needed. This is said to have a higher gear. However, this historical British ...
