I have been having trouble fitting Swissstop pads to my new hand-built alloy rim brake wheels. I couldn't get the pads to contact the rims squarely - they will only touch the rim at the part of the braking surface nearest the tyre.
It turns out that the braking surfaces on each side are not parallel: they are 24 mm wide at the edge nearest the hub and 25 mm wide at the edge nearest the tyre. I checked a cheap alloy rim and a DT Swiss alloy rim (both brand new) and in both cases the braking surfaces are parallel.
Have I got a bad set of wheels? The DT Swiss pad holders have less angular adjustment (around the vertical axis) than Shimano pad holders so I might not have noticed this if I'd been using Shimano pads.
I found this thread from 2008: Braking Surface Tapered? | Road Bike, Cycling Forums (roadbikereview.com) and these carbon rims with a tapered braking surface: PR50 Carbon Rim Brake wheel front only 700c inc tyre – Pacenti Cycle Design.
Does anyone know of a disc mount fixed cog that is 1/8 rather than 3/32? I realise I could probably get away with the 3/32 with my 1/8 chain but I would rather not, example here: https://www.sjscycles.co.uk/sprockets/16-problem-solvers-332-inch-disc-mount-fixed-sprocket-silver/?geoc=IE
2 Questions from me:
I have another one of them, not sure if it is from a previous helmet or was a spare that came with this one. I can easily enough fit the new one to teh helmet - but the straps go through the existing one. I can't see anyway to do that with the new one without disconnecting the straps from the helmet and I can't see any way to do that. Am I missing something or should i just use it without threading eh straps through the loops? I think I will have to cut the damaged one to remove it from the straps.
Question 2 is probably easier but I don't know the answer to it. I am waiting on delivery of a new bike, commuter 5 from Canyon. I have just noticed it has 650b wheels rather than 700c. I don't know much about the difference tbh. Are tyres easy to get for this size? I had hoped to use the gatorskins I have on the commuting bike I am replacing for it, but i guess that isn't possible now. Presumably the pile of spare tubes I have will be ok though since they look like they are not wildly different. What are the characteristics of a 650b vs normal 700c wheels? I don't think i have ever had anything other than 700c since I was a kid.
Edit: Can't seem to move the images. The first photo is the replacement (new) frame, the second is the one that hs snapped which has the helmet straps snapped through it. In any case I have figured it out - the helmet straps split into two on the right hand side (i was looking at left. So can split it on right hand side, feed it back out through the bit in the centre and remove the frame, then feed the strap back into the new frame. Finished now and delighted to have helmet back feeling normal again, was less comfortable with that split bit.
all fixed.
Great thanks! they'll do the job! I measured my existing mudguards and they are 35mm wide. Most mudguards that i found up to now were 38mm or wider so i was reluctant to buy them.
Bontrager make easily adjustable ones:

Thanks..i'd forgotten about Bikeinn. I've had a look and the nearest match i can see is these:
Not quite what i want as they are specifically designed for racebike frames that don't have mudguard clearance.
Maybe I need to be more specific. I’m looking for this type of mudguard set for 25mm tyres. I don’t want clip on/ass savers or race blades as my bike can take full /bolt on mudguards: https://www.cyclesuperstore.ie/shop/pc/viewPrd.asp?idproduct=147523
Bikeinn | Online store for bicycles and cycling equipment (tradeinn.com)
lots of choice here..
Cycle Super Store mudguards range...
These raceblades (€56) cover up to 25mm...
Regarding Mudguards. Anyone know where I'll get full Mudguards for a 10 year old bike with 23/25mm tyres? Alltricks, Mantel and bike24 only have Mudguards for 28mm of Bigger?
No problem. This bike maintenance thing isn't so bad once you realise that nothing is standard anywhere on the bike. Ever.
I did that before…ended up buying a new bike to fit the mudguards to! :)
This is too funny! My kid has a Cube I bought second hand and didn't seem to appreciate the need to start in a low gear on take-off - pulled the derailleur into the spokes on more than one occasion while I figured out whether he needed a long / short cage replacement / matching hangar etc. on Amazon, then realised the chain was bent etc. causing slippage. Too many Saturday mornings on this then off to the bike shop for the walk of shame...
Great thanks. I suppose that makes sense. I didn't want to order a set that ended up being too wide.
i'd say its straight across. I recently measured my new bike for mudguards and the width for the rear was just over 35mm (where a rear caliper brake would be fitted). I got 35mm mudguards and they fit perfectly
Mudguard width question:
If a mudguard is described for example as 35mm wide, does this mean 35mm straight across from edge to edge (as in diameter) or does it mean a 35mm 'arc'?
Thanks.
In my experience, always the latter
Derailleur Hanger for my Giant Defy, with Shimano 105 equipment, about 2009
From the myriad of choices, which is the right one?
Or do I just take the two bits into my LBS and start crying?
Couple of things to check. First and foremost is the derailleur hanger bent at all? Secondly, and more of a long shot, I had similar issues a while back - shifted fine one way skipped the other or vice versa. Since it was when I put on the bigger cassette I mentioned a few posts back, I thought it must have been down to that so took it to the LBS. Turns out a sliver of a strand of cable had got trapped in the shifter at some point and caused issues
fully agree with this!
Nothing in life is as sure to reduce me to tears as trying to index a rear derailleur. Christ on a bike.
I've tried and failed. Limit screws are set correctly. Cable tension has been checked. Shifting up the cassette is spot on. Shifting down started off skipping one cog, now skipping about 4.
Barring a miracle it's down to the LBS (again!) I go.
yes thanks i know...lots of juice left ! Went ahead with same tyre replacement in non-tubeless setup.
By the way.. Not sure if your aware, that "hole" in the wheel rim is a wear indicator. Once its worn away your supposed to change your wheels ans the rim has worn down to its minimum thickness.
I threw a 11-40 on my 105 Cube Nuroad a page back or two. Shifting has taken a small hit and I can't cross chain, so limit myself to 8-9 or so gears on either ring. I didn't bother using the new chain, original chain is around 114 links. The b screw did need adjusting and I needed a longer b screw to achieve this. Otherwise it works great. Big granny gear for w200...
Couldn't use a wolftooth as the cube uses direct mount.
I've put a 36T on a non-series Tiagra level rear with I think 34T capacity with no problems - there was plenty of clearance and the B screw hadn't bottomed out so I'd say a couple more teeth would have been ok.. A Wolftooth Roadlink or similar should probably give you headroom and would be my next port of call if I discover I need really low gears. Didn't the pull ratio change between Tiagra 4600 and 4700? It's probably only something to beware of if swapping out either derailleur or shifter.
You might get away with the rear derailleur, they are meant to take close to 40t anyway and Shimano are quite conservative. I'd initially just buy the cassette and chain, see if it works. If it doesn't, then order the rear derailleur but so long as you don't cross chain, I think it will be fine.
Just looking for some general advice, thinking about fitting an easier granny gear on my cube cx bike, just to make it easier when touring and hauling fully loaded bike up the gradients. Say I wanted an 11-42 cassette on the back, what else needs to be changed out? Rear derailleur I guess for starters. Shifters? new chain?

Apologies, missed the tubeless bit.
will hard wired ones work on this ? I have a spare one but not sure its fit for purpose..its botranger and i know its not tubeless
yes i plan to stick to tubeless..however if anyone else has good non-tubeless reccos i am up for it !
