Re: Deore vs Deore LX

*** Thread drift alert *** Anyone else still running Deore DX on their main touring bike? 304241A4-D3B7-45B5-A0B3-A3046DBFE565.jpeg Yep, I'm still using a pair of wheels I built about 20 years ago using those hubs, purchased as NOS off fleabay. They're still going strong, and the bearings still fee...

Re: Shimano 9speed wheels with Campy 11?

I can verify that a Shimano 9-speed RD changes almost perfectly across a Shimano 9-speed cassette when used with older Campagnolo 11-speed Ergos, as I have that setup working on one bike: 2011 Chorus 11s Ultra-shift Ergos with a Deore XT 9s RD and cassette. However, Campagnolo changed the cable pull...

Re: Steel touring frame suggestions with smaller BB drop

I'm confused if you find a frame with a 65mm drop and convert this to 650b wouldn't.the drop be even lower? 650b is smaller than 700c. You're confusing BB height with BB drop. Some manufacturers give BB height (ie distance from ground to BB centre), which is a pretty useless measurement because it ...

Re: Spoke key?

The best spoke tools grip three sides of the nipple. I use the VAR spoke key when building wheels with conventional nipples - mine is decades old and will easily outlast me. A good thing as I don't think VAR any longer make this particular tool: https://images-na.ssl-images-amazon.com/images/I/41oaZ...

Re: Headset bearing kit that will fit my current race?

From your photos it looks like a standard 1-1/8" headset with cups that press into the headtube. You can buy complete replacement headsets for just over a tenner - eg https://www.wiggle.co.uk/ritchey-logic-v2-headset/ . If you want to do the replacement yourself, you'll need some means of bang...

Re: Gates Belt Drive question.

The rear triangle on the drive side has to be able to be split so that the belt can be fitted, and you also need the frame to have some way of increasing/decreasing the distance between the crank and rear wheel to set the tension on the drive belt, either sliding rear dropouts and/or eccentric botto...

Re: Trek Domane frame failure

One of my riding friends whose son is a Trek dealer turned up a few weeks ago on a brand new Trek Domane SLR 7 disc machine. On our last ride but one the whole saddle/seatmast section started waggling around in a fairly alarming manner - something seemed to have broken in the IsoSpeed suspension stu...

Re: Bottom Bracket coming Loose

It is a genuine Campag Veloce sealed unit cartridge BB. What I cannot understand is that with the Italian thread it is done up clockwise and that is the direction the chaninrings / cranks are turning so logically, it seems to me, this should keep it from coming undone. Not the case. Look up "p...

Re: Things we need not invented yet

To contrast with cycling dead ends... A simple on-board way to immobilise / make unrideable a bike, eg that locks-up the bottom bracket. Go to Amsterdam, and you will see most of the bikes have a "nurse" lock permanently attached to the frame at the seatstays for locking the rear wheel. D...

Re: App that measures elevation

On the PC, I use the RideWithGPS website. It will plot the route for you, show an elevation profile of the route, and as you move your mouse along the profile, it indicates the gradient at that particular point. When I'm touring and don't have access to a desktop machine, I use Locus on my Android p...

Re: Narrow q factor triple chainset with steel rings

I use brifters so ramp and pinless won't work for me. From my experience they work fine. In the late 90s I raced on a bike equipped with Dura-Ace 9-speed, but I felt that the 53t chainring was bigger than I needed in the Masters 5 category, so I replaced it with an unramped/unpinned 49t ring, and d...

Re: 11speed Rear Derailleur

If you want lower than 11-34, Sunrace make an 11-36 11s cassette ( http://www.sunrace.com/en/products/detail/csrx1 ) that fits an 8/9/10 speed cassette body and works fine with the Shimano 105 7000-GS or Ultegra 8000-GS derailleurs. I have that setup running on our tandem. I have also seen reports t...
