Re: About bike shops for big people?

Somebody mentioned the fifties earlier. Born in 1947, I remember a bit about the fifties. We had sugar, we had fat. Fish and chips were cooked in lard, so were your roast potatoes and Yorkshire pudding. We ate bread and dripping, or "mucky fat" if you're from West Yorkshire. Milk was just ...

Re: finally upgrading from clunky hybrid

What will your weekend rides be? On clean tarmac a road bike is faster, but they are less suitable for the occasional track/towpath etc. If you are young, fit and strong the gearing and riding position of a road bike might well suit.....for the rest of us, the more relaxed position and lower gearing...

Re: Spa ti touring frame.

Too soon to say, haven't had a chance to give it a long test. Unloaded, so far, I'm much preferring 700c wheels over my trucker which is 26inch. I'm giving it a longer ride this weekend and will pop over to the hook of Holland start of July and report back, though I'm not 100% convinced the compari...

Re: First time commuting on a bike, I have the option to exchange but would like advice on specs please

Lithium 2 is 7 speed here, doesn't that mean screw-on? https://www.evanscycles.com/pinnacle-lithium-2-2019-hybrid-bike-EV339937 But really, 2 miles? That's 10 minutes at 12 miles an hour. A "better" bike won't save you a measurable amount of time on that trip. How much maintenance you do, ...

Re: saddle fore aft position KOPS

I would expect pushing the saddle back 3/4" to take weight off the hands. This should mean riding without tension is the shoulder muscles, so I would expect less discomfort in the neck. I think raising the bars even by as little as 1cm should help as well; in the last few years my bars have cre...

Re: Re-spacing Reynolds 725 frame

725 is OK to cold set. Personally, I prefer to pull the stays out one at a time, this avoids (for example) the right stays doing all the bending because the right chainstay is flattened to clear the chainwheel and the left stay isn't. (eg. stand on frame on floor on wood blocks, pull rear dropout up...

Re: saddle fore aft position KOPS

For KOPS I believe its traditional to hold the plumbline on the little knob on the top of the shinbone. ...this is where the patellar tendon attaches, its called the Tibial Tuberosity if you want to give it its full title. Big name for a little bony lump. ( reminds me of somebody.....) The usual (al...

Re: tube compatibility

just to clarify, I'm advocating that you can make a presta tube work in a badly drilled rim by using the locknut on the inside of the rim, i.e. to support the valve, rather than on the outside as per normal. I quite often don't bother with the locknut if it is to be fitted to the visible surface of...

Re: tube compatibility

Usually my experience is similar to (for example) Brucey and R2; but not in this case. I don't think I have had a valve pull out of a tube for a very long time ….maybe one or two tubes have failed at the tube/valve join in the last half-century. I don't bin them when they puncture, I patch them; I s...

Re: Cracked headtube - Any point in claiming against warranty?

There is somebody here https://forums.overclockers.co.uk/threads/ridgeback-bikes.17899321/ who seems to have replaced his ridgeback frame under warranty.
Got the receipt?

Re: Help to Identify Freewheel / Freehub

I've never heard of them either, but E bay has lots...https://www.ebay.co.uk/sch/i.html?_nkw=nervar+freewheel
It looks like just another screw-on (multiple) freewheel to me....some of the E bay ones look like a Shimano spline freewheel remover would do the trick

Re: Loose seatpost - Spa Aubisque frameset

As you say, take the frame back to the shop when you are in the area. If Spa's usual seatpost fits, then that's the answer....don't use a post that's undersized. If Spa's usual post is too slack, it seems to me theres something wrong with this particular frame. Its a new frame, it wants to be right....

Re: Loose seatpost - Spa Aubisque frameset

As Brucey says, 725 seat tubes (AG 455, AG457) are externally butted at the top. If you run your fingers down the top bit of the seat tube you will feel where the outside diameter steps up …..according to the Reynolds Tubing list here.. http://www.torchandfile.com/assets/images/Reynolds/Reynolds%20T...

Re: Deep Rim/Short Spokes vs. Shallow Rim/Long Spokes

When people want to "buy" performance, weight is often the first thing they look at. What might you save on a wheelset? 100 grams? Not much as a percentage of the all-up weight of bike and rider, you would do better by emptying your bottle at the bottom of a climb. A long time ago, when I ...

Re: Deep Rim/Short Spokes vs. Shallow Rim/Long Spokes

Some random thoughts... As Brucey says, you shouldn't expect to break spokes anyway. If the wheelset is adequately specified for the job and properly built and stress-relieved, then the spokes should outlast more than one rim, with rim brakes wearing the rim. A stiff rim will "share out" l...
