Speaking of which, I see bikes marketed as enduro, cross country etc. What are the major differences?

 

 

XC (Cross Country) - generally short-travel (sub-110mm) and often a hardtail (no rear suspension) but there are some XC full-sus bikes around now - steeper headtube angle and lower front-end (generally built like a racing bike with flat bars). Often ridden by people in lycra trying to get their Strava time up (more expensive XC bikes), or entry-level XC bikes being sold to new riders and the general public. 

 

Downcountry - generally 120-130mm travel forks and sometimes rear suspension as well. Set up in-between a XC and Trail bike. Super-light, short-travel and slightly more aggressive geometry than XC (slightly slacker HT angle - maybe 67-68deg)

 

Trail - slacker and more aggressive again - modern Trail bikes generally have 130-150mm travel front (and most often) rear. Slightly beefier than XC and DC bikes. HT angle of around 65-66deg these days. Made predominantly as "do-it-all" bikes for the average to aggressive rider. Also found in Hardtail as well as Full-Suspension. Lots of gear range for climbing to the top of whatever you might throw yourself down. 1x at the front and 11 or 12 speed 11-52 at the rear isn't uncommon. 

 

Enduro - long travel trail bikes that go up hill OK as well as being insanely capable downhill. Long, low, slack. Tough, long-travel suspension (usually 150-180mm travel front and rear) and in some cases long travel front-suspension with a hardtail and super-slack geometry. Also have capability of many DH bikes, but with less weight and wider range gears. Seen often at Bike Parks heading downhill at speed and defying gravity over anything that resembles a jump. 

 

Downhill (DH) - specifically made to point down a hill and go as fast as possible. 200mm + travel front and rear usually. Often heavy with beefy forks (38/40mm diameter stanchions) and usually dual-crown. These are the weapon of choice for adrenaline junkies and 16year-olds who like to break limbs. Often seen being pushed up the slightest gradient, or attached to a ski lift or trailer to be taken to the top of a mountain for a rapid descent. Tackle rock gardens, jumps, cliffs, drop-offs and other scary stuff with ease. 

 

 

 

Then of course there are Dirt-Jumpers, Gravel Bikes, weird hybrids of all of the above and whatever niche a specific manufacturer might want to cook up (google "Grim Donut"). 

 

All of this assumes the "right now" of mountain biking. A couple of years ago, Downcountry didn't exist. Only a few years ago, head angles and seat tube angles were different and everything I said above wouldn't have been true. In a couple of years, this will probably all look like nonsense as well. An Enduro bike from this year, with the most modern gear and geo, could easily be considered a DH rig from 5 or 10 years ago.

What are roadies using these days for a cycling computer?

 

I still use a Polar CS 200 CAD, which I've had for over 10 years. I does what I want, speed, distance, cadence and heart rate. I use SportsTracker on my phone to track my ride. So long as the wireless speed and cadence sensors keep working I'll keep using it but at some stage the sensor batteries will fail. At that time I will need to cut the sensors apart to replace the battery or replace the computer.

 

Any recommendations on a equivalent replacement?

I've always used basic cateye devices. Currently have a strada slim, does the basics, speed, distance, time. batteries on both units are replaceable. For hr related metrics I have a Polar M400 watch & chest strap

 

Never bothered much with cadence info. Think I'd only find that useful at the velodrome, and I'm not there often enough to justify it

Thanks. I have a wired Cateye Astrale on my hybrid. It does the job but the cadence sensor wiring has damage to the insulation. The sensor still works but for how long.

I'll have a look at the Strada. I find the cadence function quite useful on the road. The heart rate function was also very useful but of recent times I have AF which makes the heart rate function somewhat useless.

I don't know if this is the case for all wireless devices, but two issues/quirks I found..

 

The distance between the computer & sensor for my strada was pretty short, so the sensor is higher up the front fork than usual.

 

When I put my front light on the same side as the computer, it failed to pickup anything forom the sensor. my light has a metallic outer shell, which I guess contributed to that as well.

I've had no such problems with the Polar. Mind you my lights have plastic bodies. The cadence is on the lower rear fork abeam where the bottom of the crank goes past.

Here's a question for all you Mountain Bikers...

 

Anyone know where I can lay my hands on a relatively cheap pair of half-decent forks with a straight steerer and 130-140 travel for a 26" QR bike (Disc Brake compatible)? 

 

Son's trail bike has just come back from the mechanic, with the Marzocchi Bombers from 2007 unable to be repaired - no seal kits anywhere in the world - even Blue Shark couldn't source any. 

 

So in order to sell the bike, he needs/wants a decent fork to put on it (so he can get the best $ for it as it's a decent bike), or he's going to have to part the bike out, which is a real hassle.

Yeah Facebook, Trademe and AliExpress have all been explored. 

 

Have thought about a 27.5" but with a straight steerer they're harder to find. And a tad more expensive.

Very often a lot of OEM parts are off the shelf items from a third party manufacturer, in this case say a seal manufacturer. While the kit as such may not be available the individual parts may well be available. 

 

When you talk seals I'm guessing O rings and wiper seals. In other words seals that are used on hydraulic rams etc. I'd be trying around the outfits that sell these types of seals. I'd be very surprised that you couldn't buy something that works. It might take some digging on your or someone else's part to find what you need.

 

If you've got the old parts it will be possible to measure their size and go looking through catalogues to find the equivalent parts. That's what I'd be doing if it were me.

While it's probably true the fork manufacturer doesn't make their own seals, I know from chasing parts for electronics and power tools , it can be very time consuming and also doubtful, with unpublished specifications and parts that look similar. I can understand the option to simply replace the whole fork.

 

Maybe some other fork repairer will find a solution and publish it on the web.

 

Good luck with the repair Handsomedan.

Thanks. I'd think the wiper seals and O-Rings are likely able to be found somewhere, but I just don't know if I can be bothered with the trouble of finding them - it's just a matter of having the time and energy to do that, simply so that we can sell the bike, when we could replace the fork with something cheap, sell the bike, then give the old fork away to anyone that needs one for parts (the stanchions are in perfect order and the lowers still look pretty good, too).

Looks like we've found a replacement on Aliexpress - Bolany air forks. A Fox rip-off that gets OK reviews. They're cheap and will do the job without being dangerous, so we won't feel guilty selling the bike with these on.

Understandable. For those so inclined it would be a pretty easy fix but if you're not used to finding bits to repair such items it could be more of a hassle than you want.

 

I'd be a bit disappointed that the bike shop didn't pursue an alternative like this as I'd guess this wouldn't be the only situation like this they've come across. They could make some customers very happy.

I have some 26" forks but only with 20mm axles. They are getting hard to find and sought after.

 

Which model Marzocchi fork exactly? Shockcraft is bound to have everything. Sell all over the world and based in Alexandra.

 

I had a few Marzocchi forks and they are still selling seals for the 66s (35mm seals)

 

 

 

 

 

 

 

Click on Marzocchi to filter by make. 

 

Edit. One pair left for 35mm 66s
