Re: Saddle moving

If the parts that clamp the saddle rails are alloy, it might be smoothed off serrations. If the clamp parts are pressed steel then probably the lower plate has bent down a bit (as alluded to up thread), so the bolt is no longer able to secure the rails securely. Straightening the affending part migh...

Re: How do you look behind with falling off your bike

Coming late to this discussion. To look behind and still go in a straight line,the aim is to twist/rotate your neck and keep the shoulders unturned/straight. Its the turning of the shoulders that makes you vere/drift across the road. A tip I was given years ago (but perhaps not so useful in busy tra...

Re: Biscuits brake road bike under 2k

What do you want to use the bike for ie. what sort of riding/speed/distance, sunny days only, or all weathers. What is uncomfortable about your current bike ;- Position? in which case you might like to fiddle your current bike positioning to get it better, then you can buy a new bike that you know c...

Re: Peugeot 80ies racing bike - lose handlebar

Re allen key size for the stem bolt. Some French stems use 7 mm allen key size (most Peugeots I see use the normal 6 mm), though I rarely see the 7 mm bolts (once every few years at work, and that is in a city full of old bikes used daily). On the other hand, you may just have a rounded off standard...

Re: Front low rider rack for bike with suspension fork and disc brakes

Looking at the Zefal photos, it will probably fit (but worth checking fork leg/clamp diameter). If the fork legs are tapering, then the rack will probably keep working loose as it tries (successfully) to slide down the taper. Disc brakes may well cause difficulties with the fit, especially if the ca...

Re: New and Big

A bike with a cassette design rear hub (stonger design for rear axle, RHS bearings are near the frame drop out). At your stated weight, if you get a bike with a screw on rear hub you'll be breaking rear axles (weaker design, RHS rear bearings soewhere nearish the middle of the rear axle). A cassette...

Re: Triggering traffic signals with magnet?

Our county head traffic light man gave us a talk some years ago (very entertaining it was to). As regards loops in the road detecting cycles, he said they "should detect the toe cap in his work shoes". If they didn't detect a bike, they needed adjustment - most adjustments could be done fr...

Re: Help identify this bike

Seat post diameter. Take the seat post out, the diameter should be stamped somewhere near the bottom of the seat post. Butted 531 frame tube (as per 531 sticker photo) should be 27.2mm diameter, or possibly/much less likely 26.8mm diameter. The frame lug would not clamp a 25mm diameter post without ...

Re: How to prepare for an organised EVENT (soon) from zero start?

Bernard Hinault (multiple Tour de France winner) was (I think) asked how to achieve success in racing : 1. Ride a bike. 2. Ride a bike. 3. You've guessed it, ride a bike. You'll need to ride a few times a week, not just at the weekend. A modest amount during the week might not get you super fit, bit...

Re: Handlebar Tape

Yes, start the bar tape at the bottom and work to the stem clamp. However, on the top section wrap so on the way up, you are coming up behind the bars, and then down the front. The pressure/friction of your hands on the tape tends to tighten in. If you wrap coming up at the front, down at the back, ...

Siezed dual pivot calipers

On the "Is there a perfect bike for commuting?" thread on here, I posted to not use dual pivot brakes without mud guards, as they always sieze up (water + winter road salt). I had the best case yet this week at work, Campag Veloce, front and rear calipers siezed (pads sort of just about ru...

Re: Is there a perfect bike for commuting?

Not read all the posts... but don't commute with dual pivots and no mudguards. At work every winter I (and a few other on this forum I expect) get quite a few seized up front and rear dual pivot calipers (and a few other designs as well). Sometimes they unseize, often they don't. Then it is complete...

Re: Newcastle to Heathrow?

It can be as scenic/safe or not as you make it! Go down the A1 and you'll have a grim time and need good health insurance. Lots of quiet/scenic country all the way (more or less) between Newcastle and London if you avoid the large cities/industrial splurge in between. Down the center of the country ...

Re: Cassette lockring issue

Sometimes I come across stuck lock rings. Put splined tool spanner/chain whip handles on opposite sides, hold (upright) wheel on the ground/tool handles horizontal so you need to push down to loosen. Use a spare finger or 2 to grip the wheel rim/spoke, lift and thump down hard on the ground, the sho...
