Mountain Biking

grrrr just spent £500 I think upgrading my Cannondale trail 4 with XT shifters and brakes, Renthal fatbar, dmr vault pedals, selle italia Maxflite saddle, some dmr death grips.
I've been day drinking on my day off so it'll be a nice surprise for me tomorrow. I'll get a better fork and wheelset at some point.

I already have an XT crank and rear mech on it.
 
Driving myself crazy with tyre choices!

I originally had the tyre combo that came with my bike — Continental Mountain King II Racesport 2.4 (F) / Continental X-king Racesport 2.4 (R)

It was fine, but I often found the level of grip lacking and ultimately I got a split in the X-king.

I replaced this with a Magic Mary (F) / Hans Dampf (R) combo and I've never had an issue with grip since.

However, I find that the rolling resistance is quite high, and as I'm doing longer rides now instead of short blasts around the local trail centre, I would like something a bit lighter with less rolling resistance, but still enough grip for when I do decide to hit the trails…

So, I'm looking for a combination that's lighter, with less rolling resistance but still has a decent level of grip. If I can do that by adding one tyre to my current lineup then great. if I have to buy two new tyres then I will but I'd rather avoid it if possible.

I have seen suggestions of moving the HD to the front and sticking a Nobby Nic on the rear, but I've never been that fond of NNs.

I could always go Maxxis, but the range is mind-boggling…

Any suggestions?
 
DHR2/Aggressor seems quite common.

I've ran the DHR2 upfront before and it was ace on loose hard packed stuff. Minion SS on the rear is awesome, but maybe not so much for the UK. I'll be trying it, as I love it and if it's crap I'll change it to an aggressor with the 2.5 DHF upfront.

Yet to try the DHF 2.5, but if its as good as the DHR2 then I'll be very happy.
 
Currently running a DHR (R) and HR2 (F) on the Crush but the Five - I've just purchased (waiting for it to arrive) comes with HR2 F & R.
 
Thanks guys, looks like a lot of love for Maxxis. :)

I guess the thing I want to avoid is spending the best part of £100 for a setup that's similar to my old Conti combo or my current Schwalbe combo.

Otherwise, I may as well just replace my old X-king…

I need a Demo Day for tyres!
 
Sooo, I'm thinking of building a full suss, reusing parts from my old bike: https://www.evanscycles.com/pinnacle-iroko-2-2016-mountain-bike-EV244133

So frame, rear shock and drivetrain needed I think.

I've never built a bike before so not sure what to look out for in terms of fittings etc. Does the frame need to be a specific type to work with the parts I have, or are frames fairly generic? Any other foreseeable pitfalls?
 
Headtube length, make sure it's not longer than the current bike unless you've got a load of spacers under the stem.

Front mech, are you still running this? If so you may be forced to go 1x as a lot of frames don't have front mech mounts/routing.

Also, you'll be wanting a non-boost frame so that rules out pretty much every single 2018 frame, everything is boost now.

Then there's the obvious things like seat post diameter, bottom bracket and headset differences.

Ok so, I put my old Continentals back on (I stuck a tube in the rear) and did my usual loop at my local trail, as per this thread.

I took two minutes off my previous PR (a 10.7% improvement), and while some of that is no doubt due to my improving fitness, I could feel the reduction in rolling resistance and I believe that the majority of that time was down to the tyres.

Considering I had to overtake a bunch of people (some on the climb and some on the descent), I reckon there's more improvement to be had as well. However, there was one section where I had to back out due to a lack of grip, which was always my concern with the Continentals.

I've done a bit more research, and in terms of weight, a DHF/DHR paired with an Aggressor isn't going to make much difference compared to my MM/HD setup (although I appreciate there may be a rolling resistance improvement).

The Maxxis website suggests an Ardent Race (F) / Ikon (R) combination as one of the lightest/lowest rolling resistance combinations — only slightly lighter than a Nobby Nic (F) / Rock Razor (R), but with both of these options I worry about the lack of grip — if it's any less than my current Conti's I don't think it would be right for me, even if it was slightly faster overall.

As I said, I don't want to replace both tyres and end up with a similar setup to what I've got, nor do I want to end up with something less grippy than the Continentals. However, I know I need to replace the X-King so if there's a better alternative to the Mountain King I'd happily go for it.

Maybe a pair of Nobby Nics would be the best compromise — 1.53Kg for the pair, decent enough grip and reasonable rolling resistance… It's all so complicated!
 
New Calibre Triple B and Boardman Mtr 8.9 look good value!.

I'm kinda drawn to the new boardman. First review out is very positive.
 
The new boardman looks nice too, as well as having a decent spec! My 2014 model has served me very well too. I'll certainly consider one as a replacement if I back off the idea of buying something higher end.

Irish_Tom, if you are finding the MM/HD combo a bit too draggy why not put the HD on the front and try a Nobbly Nic on the back perhaps? Saves buying 2 new tyres. That's about as much advice as I can muster mind, I run the same tyre combo as you currently and find it great. Perhaps we ride on different surfaces/terrain. I went from a oem pair of NNs to the MM/HD and whilst I never timed the differences, I had far more confidence on corners and braking that I've never looked back and questioned the choice.

Where do you have grip issues- front, rear or both? Could always put a Mountain King on the rear too. What are your pressures, can you run them lower (especially on the front)? Shouldn't have too many issues with those tyres in 2.4" format.

Help - I have this bike which has been converted to a single crank https://www.bikeradar.com/mtb/gear/...kes/product/review-boardman-ht-team-12-46330/

Chain has snapped and I've been told this is due to me going over jumps on a none jump bike but which makes sense but I don't want to fork out for a proper full suss until I feel like I can get abit more confident over the jumps and I believe the hard tail will be fine for now,

So a few question, how hard is it to replace a chain on a 9 speed?

Been told a chain guide will help this to stop happening again - any ideas what chain guide I will need to buy this has been converted to a single crank and the extra gear's have been cut off (As a friend told me to do this as I wouldn't need them)

Do I need to know what exactly the crank is before knowing what chain guide i need I'm guessing?

Yeah, there's no doubt that MM/HD is a cracking combination for maximum grip. It really has given me a lot more confidence going downhill, both on flow tracks and at more technical trails. I just noticed a few times when riding with friends that they were able to pull away from me with little effort and (as per my other thread) I'd hit a bit of a plateau when it came to my PR times at my local trail. NN on the back with the HD up front may well be a decent compromise — I've seen that combination recommended elsewhere, but the HD is pretty heavy and might be a bit overkill for the summer months on the trails I'm riding.

On Sunday there were two moments when I had to back out — one was cornering on quite a narrow off-camber trail, and I just couldn't steer in the way I normally would with the MM/HD. Although I may have got my weighting wrong, I feel like this was a bit of both front and rear not digging in. On the other section, I lost the rear, which was always my issue with the X-King before.

In terms of pressure, I normally run about 22psi front, 25psi rear, although as I had to stick a tube in on Sunday for the X-King, I was running that a bit higher around 33psi.

Although the difference in weight is minimal, a pair of Nobby Nics should provide better grip with lower rolling resistance (according to bicyclerollingresistance.com) compared to the Mountain King / X-King combo.
 
NobbyNic front and rear, go for the new Addix speedgrip compound, lighter and grippier, and harder wearing. EVO for their best tyre in their lineup, and also snakeskin walls for rock protection. I run 2.35 front, 2.25 back, can be had for 40 euros a tyre from Germany, with 6 euro delivery. Between 600-700g a tyre depending on wheel size.

I've not come across a lighter XC/trail/big ride out tyre, that goes tubeless beautifully, yet offers incredible grip.
 
PS typed all that before I seen you were considering the double NN lol

Also find them great on all surfaces, whether i'm doing loads of roads joining up trails in the hills, wet/dry, 35psi fast paced nightrides, or 25psi techy stuff.

Run the same combo on my 150mm 26" trail bike, and 120mm 27.5" XC bike.

Thanks toprock, definitely adds weight to some of the other research I've been doing… food for thought. :)
