Re: Bar End Gear Levers - advantages?

Well, no-one else has mentioned this so I will. To me the big difference between DT and BE is that you can use BE's whilst keeping a 2 handed grip on the handlebars. Change down tube shifters with both hands on the bars? Which bit of your anatomy do you push the lever with? Eh? Oh, I misread Martin...

Re: What To Do With A 1960s Frame - PT Stallard

I'm back to the 5 speed screw on freewheel and either single or double chainset idea - it'll be much easier and cheaper :D Fickle? Moi? I've been thinking about modern components which are compatible with 5 speed freewheels myself recently. The new Shimano Claris groupset (used with an 8 speed chai...

Re: What To Do With A 1960s Frame - PT Stallard

What about modern Sturmey Archer IHG at 120mm OLD? I gave that serious thought when I was building my bike. What put me off was the cable run, the 1960s approach of running the gear cable along the top tube struck me as really ugly... http://www.perthvintagecycles.com/2011/02/my-1950s-speedwell.htm...

Re: What To Do With A 1960s Frame - PT Stallard

My 1960s Mercian has a 120mm drop out spaing. SPA Cycles cut down a 130 OLN freewheel hub to 120mm and built me a set of wheels for it. I later respaced the hub myself to 124mm, because I discovered that, even with the adjustment screws as tight as they would go, the travel on a Shimano 105 9 speed ...

Shimano 105 Front Mech With 8 Speed Chain?

I’m presently using a 9 speed Shimano 105 rear mech with an 8 speed chain and a 5 speed freewheel (as recommended by CJ in the Shimergo article on this website). If I buy a Shimano 105 front mech, will it also work with an 8 speed chain? Or will the cage be too narrow to accept an 8 speed chain? I’l...

Re: 'Alpine' Crankset?

But then there is also the added faff off the front mech, putting it on and off. . My (moot) point was that you can tour on a 1 x 9 providing the single chain ring is small enough. But like I said, it's a moot point. To make the alpine crankset idea really take off there would need to be a reasonab...

Re: 'Alpine' Crankset?

Originally I thought about a 1x9 spd set up but this would then compromise the 'touring' side of the bike - hence the idea of building an 'alpine crankset', gears for every occassion whilst cutting out (in theory) unused gears. Even on a fast day ride, 42x11 would provide a decent speed. How often ...

Re: 'Alpine' Crankset?

So if 42/22 is the next big thing (for some at least), the question is, what's the most suitable front mech?

(Assuming use of a double front chainset to keep the q factor down).

Re: Back wheel advice for vintage Peugeot

I'm surprised that the frame spacing is 130mm. 126mm would be normal for a 6 speed freewheel. If the spacing is 126mm, your options are to... 1. Buy a 126mm 6 speed freewheel hub (I think Spa and SJSC sell them) and get a wheelbuilder to build it into a new wheel. 2. Take your existing wheel to a wh...

Re: 'Alpine' Crankset?

There are a lot of compact doubles now with a 34 or 36 inner ring that have found huge favour in as much as they offer a comfy, high efficiency cadence that suits the regular-type cyclist. To me, a 42 misses this 'cadence sweet spot' - too low and inefficient, especially in the context of touring a...

Re: 'Alpine' Crankset?

But there's a big difference between a one hour race and riding all day everyday with a bad chainline :? I just worked out the gear ratios. I suspect that the OPs set up makes most sense for someone living in a flat area. With a 40/24 chainset and an 11-28 cassette you would have a very acceptable ...

I take your point about the chainline, on the other hand plenty of cyclo cross riders race on a 1 x 9 set up with a similarly dubious chainline.

Re: 'Alpine' Crankset?

Had originally thought about changing the triple crankset to a single ring and running a 1x9 spd set up but I am hesitant to lose a very low gear If you're going to line up the 40t ring with the middle of the cassette, and use that chainring with all the rear sprockets, it might be a good idea to u...
