Questions
Everything asked across the guides, in one place.
How often do I need to re-wax?
Roughly every 250 to 350 km in dry conditions, and every 100 to 150 km through a wet winter. On a 10km each-way commute that is about once a month in summer and every two weeks in bad weather. The chain tells you when: it starts to sound dry and looks grey rather than waxy.
Can I just wax over the factory grease to save time?
No, and this is the mistake that produces most of the negative opinions about waxing. Factory anti-corrosion grease is designed to survive storage and shipping, and wax will not bond through it. It will look fine coming out of the pot and flake off during the first wet ride.
Is waxing worth it if I ride 5km each way?
Probably not, on cost alone. At 2,500 km a year you will replace a chain roughly every eighteen months on oil. Waxing saves you perhaps one chain over three years, which does not repay the evenings. Do it because you dislike a black drivetrain and black calves, which is a legitimate reason, not because the arithmetic says so.
What temperature should the wax be?
85 to 95 C. Below 80 C it will not penetrate the rollers properly, and above 120 C the additives begin to separate. Use a thermometer rather than a slow cooker's own setting, which is usually optimistic by twenty degrees in either direction.
Does wax work in the rain?
Yes, but the service interval roughly halves. Wax does not wash off in the sense that oil does, but water displaces it from the rollers over time and the chain will start sounding dry. Riders in persistently wet climates often run wax in summer and a wet lubricant through winter, which is a perfectly sensible answer.
Can I use a candle or plain paraffin?
It will work, badly. Plain paraffin has no friction modifiers and wears out of the rollers within about 100 km. The additives in a dedicated hot-melt wax are most of what you are paying for. If you want to experiment cheaply, do it knowing the interval will be much shorter.
What if I cannot remove my chain?
Then waxing is not available to you without a workshop visit. Immersion waxing requires taking the chain off every time, which requires a reusable quick link. Many factory chains are riveted only. Fitting a quick link is a five-minute job with the right pliers and is worth doing regardless.
Do I really need a caliper, or can I use the numbers printed on the parts?
Use printed numbers when they exist, but most stock commuter bikes have nothing printed on the bar or the post. A caliper costs about the same as one returned part, and it takes the guessing out of four separate decisions. If you only measure one thing with it, measure the seatpost.
My bar measures 25.4mm at the grips. Is that wrong?
No. 25.4mm is the old imperial mountain bike standard and still appears on some cruisers and older bikes. It is less common than 22.2mm but perfectly normal. Grips are made in both sizes, so the only mistake would be ordering 22.2mm parts for it.
How do I measure tire clearance without taking the wheel out?
Spin the wheel and look at the tightest point, which is usually the chainstay bridge or the fork crown. Slide something of known thickness into the gap on each side. A standard coin is a useful reference: if a coin fits on both sides with room to spare, you have roughly 3mm. If nothing fits, you have no room for a wider tire.
I have eyelets on the dropouts but nothing on the seat stays. Can I still fit a rack?
Usually yes. Most racks include P-clamps or an adjustable strut that clamps to the seat stay tube. It is less rigid than a bolted mount and it slips if you overload it, so treat the rack's rated limit as a firm number rather than a target.
Does any of this apply if I only want to change the saddle?
Partly. A saddle itself fits any post with a standard clamp, so you do not need the seatpost diameter for the saddle alone. You do need it the moment you consider changing the post, adding a suspension post, or fitting a seatpost rack or rear light — and most people get there within a year.
The shop measured my bike when I bought it. Is that enough?
It is enough for the frame size and nothing else. Shops record frame size and standover, not bar and post diameters. Take the four measurements yourself once, write them in your phone, and you will never need to do it again for that bike.
How long does it take for numbness to go away after a fix?
Nerve irritation from a single ride usually clears within an hour. If you have been riding the same setup for months, expect a few weeks of improvement rather than an instant fix, and be aware that persistent numbness lasting days is a reason to see a doctor rather than to buy another part.
Are gel grips better than firm grips?
Not usually, and often worse. Gel compresses under sustained load, which means it bottoms out on a long ride and leaves you with less effective support than a firm compound that spreads the load across a wider surface. Firm and wide beats soft and narrow for anything over an hour.
My hands only go numb on longer rides. Is that still a fit problem?
Almost certainly yes. Short rides mask fit problems because you shift position constantly without noticing. Time on the bike is what exposes a position that puts too much weight forward. The fix is the same: saddle tilt first, then reach, then grips.
Should I get bar ends or a second hand position instead?
If your route includes stretches over an hour, a second hand position helps more than any grip does, because changing position is what actually lets a compressed nerve recover. Bar ends are the cheap version; a bar with more sweep or a different bar shape is the thorough version.
What torque should I use on lock-on grip bolts?
Usually 2 Nm, and check the printed figure on the clamp. This is low enough that it feels undertightened by hand, which is exactly why people crack the collars. Over-tightened lock-on grips fail without warning, and they usually fail while you are pulling on the bar.
Do padded gloves solve this?
They help at the margins and they hide the underlying problem. If padded gloves are the only reason your hands are comfortable, the weight distribution is still wrong and it will show up somewhere else, usually as neck or shoulder fatigue.
