mp1156 wrote: 4 Aug 2023, 7:41pm Yes, those are the ones I already bought. Got them for £18.99 of Amazon (I was surprised Amazon was much cheaper than Decathlon). Local bike shop said they can do £10 per shifter including brakes.
If that includes cables - brakes and gears - that fitting job is a bargain. Sometimes the shifters come with gear cables. Again sometimes the existing brake cables can be reused if not frayed. These can be extra costs to consider.

Re: Need shock advise. Carrera vengeance 24 spd

Bike shops tend to have old forks kicking about. The better condition the more you will pay for them. Just make sure they're suitable for 27.5 wheels and the rotors and calipers match up. Also check that the steerer part of the fork is long enough. (It may have been cut) The bike shop manager will advise you.

Re: How to protect skin while riding?

Check online for a buff that is described as lightweight. The heavier ones are ideal in the winter but the extra thin versions are more comfortable in the heat and you can breathe easier if it's over your mouth and nose area.

Re: Help Needed for Components

I would take your bike to a bike shop and ask for advice, explaining what you think you're after and having a good discussion on options with the staff. There will be no requirement to go ahead with any work until you approve and agree a price. Come back and tell us about the shop's proposals, together with costs, and your own ideas following the discussion. Then, knowing the full facts, we'll advise you about the next steps.

Re: Squealing Rear Hydraulic Disc Brake

Organic pads tend to be quieter but wear quicker. You can experiment with the fine positioning of the caliper by loosening the fixing bolts and judging the alignment with feeler gauges. Try the caliper in various positions in relation to the pads. When the brake runs silently you've solved it but I found it took much trial and error.

Could do your own swap over of bits. Does sound like £80 covers the set up of the wheel plus retruing of gears.

Re: Mystery creak

Check your rear wheel. Clean and lube quick release. Grease hub bearings. Oil spokes at nipples and crossovers. Make sure there's no slack in spokes. Bit of work involved but worthwhile.

Re: Promax disc brake caliper issues

Having re-read the post and comments it may be that you are referring to the threaded pin that holds the pads and spring in place. Use a torx as suggested above and replace it with a split pin. Halfords will sell you a packet of them - or a bike shop will give you one from the Jagwire retailers bulk pack.

Re: Promax disc brake caliper issues

I can't work out why you would need an Allen key to adjust an inline control on a disc brake cable. However it might not be inline adjustable but instead adjustable through an access port in the caliper body to the back of the piston. If this is the case, it would be hard to reach with a torx key. If you could pull out the pads with pliers you might be able to insert the small bent end of an Allen key into the reverse of the Allen headed screw in the centre of the piston. Works with other brake types. To be honest, I think it would be more practical to change the calipers to ones made by other companies. Shimano and Clarks do pistons that will fit. The cheaper ones are single piston operations. Post mount are readily available. You would need to do some homework by Googling comparisons to make sure you get suitable replacements. Or you could try a chat with one of the Decathlon mechanics who will know what fits and what doesn't.

Re: Wee Sprocket

Sure it's not a tensioning issue or the H limit screw needing adjusted? If there's a rogue tooth on the smallest cog you can straight it with a chisel or long nose pliers or file it down.

Re: whats this worth ?

£100 to £150. Top price if everything's working. It's approx 30 years old but wouldn't cost much to change parts, again assuming that fork and wheels are in reasonable condition.

Re: Recommend me a multi tool

The tricky gear lever screws are the ones in the cover of the Tourney trigger. The heads wear with continual opening and closing of the cover when changing cables. There are small lips in the screw recess to stop the screw itself from dropping out onto the floor but these are plastic and easily broken. We have used a whole range of screwdrivers on Tourney triggers but the go-to one (in bike shop workshop) is always the Magnusson 1.4 flat head driver which we bought for £2.50 from B&Q. As well as having a tough precision blade it has a long reach and a chunky soft grip head. Cheap but worth its weight in gold.

Re: Help with Indoor bike trainer.

TrevA wrote: 11 Apr 2023, 2:15pm If you buy a wheel-on trainer, you may struggle. They are designed for quick release axles and your bike doesn’t have one, it has a solid nutted axle instead. So the axle ends won’t fit into the trainer. You also appear to have knobbly tyres, which would not run smoothly on the roller of the turbo trainer.

You could possibly convert your rear wheel to quick release by replacing the axle (I did this on my wife’s Raleigh Pioneer). Or you could just buy a quick release rear wheel and smooth tyre - you can buy trainer specific tyres that are harder wearing than a normal tyres would be, but you can only use such tyres on the trainer and not on the road. Your bike looks quite narrow at the rear end, which again could cause problems - most rear wheels are 130mm or 135mm wide, to fit between the rear drop outs. Yours might only be 126mm, which is the old standard from quite a few years ago. Try measuring the distance between the rear drop outs (where the wheel fits into the frame). Best done with the rear wheel removed.

It’s possible to “spring” a frame to fit the extra 4mm of axle, but it can put extra strain on the frame and may cause it to crack eventually. You can also have the frame cold set to accommodate the wider wheel i.e. permanently widening the frame, but then you wouldn’t be able to use your existing wheel.

You will also be surprised how boring riding along on a turbo trainer can be. I’ve owned a couple and they hardly got used due to the boredom factor. I’ve now got a Wahoo Kickr which can be used on interactive Apps such as Zwift, which has been a game changer for me, but it’s a fair investment to get an interactive trainer to use with such Apps.
First class advice. Summed up perfectly.
